Ortholinear Keyboards: The Complete Grid Layout Guide (2026)

Ortholinear keyboards replace the diagonal row stagger inherited from 1870s typewriters with a perfectly rectangular grid, and in 2026 they remain the most philosophically pure — and most demanding — layout in the enthusiast keyboard world. For anyone arriving here after reading the 40% keyboard guide, the natural next question is whether a grid layout like the Planck or Preonic actually delivers ergonomic benefits or simply replaces one arbitrary convention with another. The short answer is that ortholinear is a coherent design philosophy, not a magic ergonomic cure, and understanding that distinction is the difference between a tool that transforms a workflow and a $300 paperweight.

The category was effectively created in late 2014 when Jack Humbert, working with Pierre Carrier and the r/MechanicalKeyboards community, published the original Planck — a 4×12 grid of 47 or 48 keys powered by the then-brand-new QMK firmware. Twelve years later, the OLKB ecosystem has splintered: the Planck EZ was discontinued by ZSA in August 2023, Drop's storefront shut down on March 31, 2026 after the Corsair acquisition, and the direct olkb.com store sits dormant. Yet the category itself is thriving — Keychron, Epomaker, KBDcraft, and a dozen small vendors now ship true-grid boards, and the split-ortho cousins (Corne, Kyria, Ferris Sweep) have arguably become the ergonomic mainstream.

This guide separates myth from mechanics. It walks through the 1878 mechanical accident that gave the world row-stagger, the critical-but-constantly-confused difference between true ortholinear and column-staggered layouts, the realistic adaptation curve (expect a meaningful typing-speed drop and two to six weeks to recover), and the firmware layers that make a 47-key Planck functionally complete. It then inventories every significant ortho board still purchasable in 2026, with honest notes on availability, scarcity, and which "ortho" marketing labels are actually column-staggered.

The goal is not to crown ortholinear the future of typing — it is not. The goal is to give a clear, didactic map so a reader can decide whether a grid, a column-stagger, or a well-made staggered board best fits their hands, their software, and their tolerance for a retraining period.

The historical mistake: why QWERTY is staggered (1878)

The diagonal stagger on every laptop and office keyboard shipped in 2026 is a fossil of a mechanical problem solved in 1878. Christopher Latham Sholes filed US Patent 207,559 on August 27, 1878, covering the Sholes & Glidden typewriter that became the Remington No. 2. That patent, together with an earlier 1868 application (US 79,265), documents the keyboard that would calcify into QWERTY.

The machine used an upstrike typebar mechanism: each key connected through a linkage to a metal typebar that swung up from beneath the platen to strike the paper. Adjacent typebars, sharing a pivot ring, would physically collide and jam if two neighboring keys were pressed in quick succession. Two design choices addressed the jamming. First, the letters themselves were rearranged so that common English digraphs (TH, ER, ED) were spaced around the typebar basket rather than adjacent. Second — and this is the ortholinear-relevant part — the key rows were offset diagonally so the mechanical linkages connecting each key to its typebar could run in parallel without fouling each other. The row stagger is a consequence of linkage geometry, not ergonomics.

Historians are not fully unanimous. Koichi and Motoko Yasuoka published an influential 2011 paper in Kyoto University's ZINBUN journal arguing that QWERTY evolved primarily from feedback by Morse-code telegraph operators transcribing incoming signals, not from pure anti-jamming logic — and they note that the adjacent E-R pair (one of the most common English digraphs) contradicts a pure jam-avoidance theory. The mainstream Smithsonian-endorsed account combines both: typebar mechanics constrained the rows, telegraphy and commercial testing shaped the letter placement. Either way, the constraint was mechanical, not human.

The constraint disappeared in 1961 when IBM's Selectric replaced typebars with a rotating typeball, and again in the 1980s as computer keyboards moved to pure electrical switches. There has been no mechanical reason for row stagger in sixty-five years. It persists through what economist Paul David, in his 1985 American Economic Review paper "Clio and the Economics of QWERTY," called path dependence — millions of trained typists, installed hardware, and manufacturing tooling make coordinated change practically impossible. Ortholinear is the answer to a simple question: what would a keyboard look like if it had been designed after 1961 instead of before 1878?

Ortholinear vs column-staggered: the critical distinction

The single most common error in online keyboard discussion is conflating ortholinear with column-staggered. They are not the same, they are not interchangeable, and the ergonomic arguments for each are different. This distinction matters because most boards sold as "ortho" on Amazon in 2026 are actually column-staggered, and the two layouts feel different in the hand.

True ortholinear means a perfectly straight rectangular grid — every row is a horizontal line, every column is a vertical line. Planck, Preonic, XD75, Idobao ID75, Helix, Boardwalk, Contra, Epomaker Luma40, Keychron Q15 Max, and KBDcraft Israfel are the major examples. The grid is geometrically regular.

Column-staggered boards abandon horizontal row alignment. Each column is shifted vertically to match the natural length of the finger that types it — the middle-finger column pushes up, the pinky columns drop down, producing a subtle wave or zig-zag. The rows are no longer straight; the columns are. The Kinesis Advantage, ErgoDox and ErgoDox EZ, Corne (CRKBD), Kyria, Atreus, Lily58, Iris, Sofle, ZSA Moonlander, and Dygma Defy all use column-stagger.

Both philosophies reject the 1878 diagonal row-stagger, which is why they are frequently lumped together as "ortho." But their ergonomic logic is opposite. True ortholinear is a geometric argument: the grid is regular, so finger training becomes regular. Column-stagger is an anatomical argument: fingers have different lengths, so the columns should match that fact. The Dygma engineering blog puts it bluntly: column-stagger promotes more intuitive finger placement and further reduces wrist and finger strain.

Community confusion runs deep. Vendor listings routinely call Corne boards "split ortholinear." Amazon product pages label the Keyboardio Atreus as an ortholinear keyboard despite its explicit column offsets. Even experienced reviewers occasionally swap the terms. A useful test: if the top row of keys forms a straight horizontal line, it is ortholinear. If the top row curves or zig-zags to follow finger length, it is column-staggered. Jack Humbert's OLKB designs are strictly grid; most of the ergonomic-split community has moved toward column-stagger. Treat them as siblings, not twins.

The OLKB community story: Jack Humbert, r/olkb, and Drop

The modern ortholinear scene has a single origin story and a single central figure: Jack Humbert. Based in Fort Wayne, Indiana, Humbert briefly studied physics and computer science at Purdue before leaving to work on guitars and software, and built his first mechanical keyboard in late 2014. That keyboard became the Planck, incepted in the r/MechanicalKeyboards community, named after Max Planck in its second forum post, and co-designed with Pierre Carrier. Humbert went on to found OLKB, LLC and to start the QMK firmware project, which in April 2026 sits at roughly 20,290 GitHub stars and supports more than 3,000 keyboards.

The dedicated r/olkb subreddit was created alongside OLKB in 2014 and has operated as the community's primary gathering place ever since, supported by a tens-of-thousands-strong community of ortho and QMK enthusiasts. The culture is heavily DIY: build logs, firmware patches, keymap screenshots, and revision-by-revision discussions of Planck group buys have filled the sub continuously for over a decade.

Distribution was dominated for a decade by Drop (formerly Massdrop). Every Planck revision — rev1 in 2015, iterative revs 2 through 5 on the ATmega32U4, the STM32-based rev6 in 2018 with Kailh hot-swap and USB-C, the rev7 pre-order in March 2023 at $99–$129 — shipped primarily through Drop's group-buy storefront. Preonic followed the same pattern through its rev3 refresh. Corsair acquired Drop in July 2023, and in March 2026 Corsair wound the standalone storefront down: the last day to order was March 25, 2026, with closure on March 31. A subset of Drop-designed products migrated to retail.corsair.com, where Planck V7 kits are listed at $129 but almost entirely sold out as of this writing.

The practical upshot for 2026 buyers is that the OLKB ecosystem is now secondary-market dominated. The olkb.com store is effectively empty. ZSA retired the Planck EZ on August 15, 2023. 1upkeyboards no longer stocks Planck kits (it sells the Pi40, a Raspberry Pi Pico–based Planck-compatible clone, instead). The Planck legacy lives on in community forks, firmware maintenance, and a thriving used market on r/mechmarket and eBay. Newer ortho entrants — Keychron, Epomaker, KBDcraft — have stepped into the production vacuum with modern hot-swap and wireless features, but none has the same community gravity Humbert's designs held in the 2010s.

Pros and cons of ortholinear keyboards

The honest case for ortholinear has four parts. First, columnar finger travel is geometrically simpler — each finger moves only up and down within its column, eliminating the diagonal reach trained into every touch typist by row-staggered convention. Second, every key is 1u, which makes keycap compatibility straightforward once the right set is sourced. Third, compact footprint — a Planck is narrower than a 60% board by about 20mm and occupies dramatically less desk space than a tenkeyless. Fourth, forced layer discipline. A 47-key Planck cannot avoid using QMK layers for numbers and symbols, which pushes users toward more efficient home-row-biased workflows that tend to carry over to any keyboard.

The honest case against is equally clear. A straight grid ignores the fact that human fingers are not the same length. The index and middle fingers reach further than the ring and pinky; a flat grid forces the short fingers to travel as much as the long ones, and many typists find this fatiguing rather than liberating. The adaptation curve is real and steep — a 30–50% initial typing-speed drop is common, with recovery measured in weeks rather than days. Non-split ortholinear keyboards do not solve ulnar deviation, the angle mismatch between straight hands and a single rigid board that causes much real-world wrist pain; column-staggered split boards address that, but a solid Planck sitting centered on a desk does not. Anyone whose motivation is primarily wrist relief should read the ergonomic mechanical keyboards guide and consider a column-staggered split board before committing to a Planck.

There is also an ecosystem cost. Standard GMK, Cherry, and OEM keycap sets are sized for row-stagger, and while most modern sets include an "Ortho Kit" add-on, buyers must double-check. A misplaced 1.5u shift on a 1u grid position is a common and expensive mistake.

The adaptation curve

Every honest review of an ortho board describes a slump. The specific numbers vary — some reviewers claim return to normal speed within a day, while others at three weeks are still adjusting — but the pattern is consistent. Expect a meaningful initial drop (typists commonly report 30–50% of their previous WPM on day one) and a full recovery window of roughly three to six weeks with regular use. Isolated datapoints fall outside that range in both directions.

Two variables predict where on the curve a given user lands. The first is prior touch-typing discipline. Using the ring finger to press Q and P, pressing X with the middle finger, or using the index finger to press C are common hunt-and-peck compromises that row-stagger tolerates and ortho does not. A proper touch typist already uses correct finger-to-column assignment and mostly needs to unlearn the diagonal offset. A hunt-and-peck typist is effectively learning to touch type for the first time, and their adaptation can stretch to months. Rough estimates suggest roughly 6–8 hours of deliberate practice for experienced typists versus 12–16 hours for average users to approach prior speed.

The second variable is board size. A 75-key XD75 or Idobao ID75 keeps the number row and many symbols in fixed positions, so adaptation is dominated by the row-stagger-to-grid transition alone. A 47-key Planck simultaneously forces the user to learn the grid, the lower/raise/adjust layer chording, and a shrunken modifier set — three things at once, which compounds difficulty. First-time ortho buyers who are not already comfortable with 40% layouts will usually find a 60- or 75-key board a gentler on-ramp.

Practical advice from the r/olkb consensus: use a dedicated ortho-friendly typing test (monkeytype, keybr) for twenty minutes a day for the first two weeks, resist the temptation to switch back to a staggered board during that window, and accept error rates above normal rather than chasing speed. Reviewers who pushed through the first fortnight almost universally report permanent adaptation; reviewers who fell back to a staggered board within the first week almost universally report the ortho experiment "didn't stick."

Ortholinear and alternative layouts: Colemak/Dvorak synergy

A recurring r/olkb debate asks whether to learn an ortholinear board and an alternative keyboard layout — Dvorak, Colemak, or Colemak-DH — simultaneously or sequentially. Both camps have evidence. The pro-simultaneous argument is that full retraining happens exactly once: muscle memory is being rebuilt from scratch anyway, so there is little additional cost to remapping the letters at the same time. Detailed treatments of the major alternative layouts live in the QWERTY vs Dvorak vs Colemak guide.

The pro-sequential argument, made most clearly by Peter Jang in his Planck learning series, is that each variable added to the retraining extends the timeline non-linearly. Learning grid geometry on QWERTY, then layering Colemak onto a now-familiar grid, is often faster in total wall-clock time than learning both at once.

The pragmatic community consensus is that users who already touch-type fluently, have six weeks of tolerable typing degradation available, and are strongly committed to Colemak anyway should combine the two. Users switching to ortho to see if they like it, or who rely on consistent daily output, should stage the changes — learn the grid first on QWERTY, then consider Colemak after stabilizing. The synergy is genuine but not magical. Ortho + Colemak-DH + home-row mods is the endgame for many ergonomic-keyboard converts, but it is rarely the fastest path there.

Planck deep dive

The Planck is the defining 40% ortholinear keyboard. A 12-column, 4-row grid, in its most common configuration a 47-key MIT layout with a 2u spacebar, or optionally 48 keys with two 1u thumb keys replacing the spacebar. In 2026 three distinct Planck lineages exist, in varying states of availability.

Drop + OLKB Planck V7 — the current-generation kit, moved from drop.com to retail.corsair.com following the March 2026 storefront closure.

• Layout: True ortholinear grid.
• Grid: 4 rows × 12 columns.
• Key count: 47 keys (with 2u spacebar) or 48 (grid).
• Form factor: DIY kit; case, PCB, plate, screws, USB cable included — switches and keycaps sold separately.
• Switch compatibility: MX hot-swap via Kailh sockets.
• Firmware: QMK with official VIA/Remap support; speaker onboard.
• Connectivity: Wired USB-C only.
• Case material: CNC anodized aluminum; available in black, red, and green for V7.
• Price: $129 MSRP at retail.corsair.com; almost entirely sold out April 2026.
• Keycap compatibility: Needs 1u all-alphas plus 1.25u or 1u modifiers and a 2u spacebar; ortho keycap sourcing pitfalls are covered below.
• Best for: DIY builders who want the canonical OLKB experience and are willing to hunt secondary-market stock.

Verdict: Still the reference 40% ortho, but scarce in 2026 — buyers should expect a used-market search or a wait for a restock that may never come.

Planck EZ (ZSA Technology Labs) — officially discontinued August 15, 2023.

• Layout: True ortholinear 4×12 grid.
• Key count: 47 (2u) or 48 (grid), MX hot-swap.
• Firmware: ZSA Oryx graphical configurator + Wally flasher, built on a ZSA fork of QMK.
• Connectivity: Wired USB-C; no wireless.
• Case material: Hard plastic (white or black); Glow SKU included RGB.
• Price: Final list $220–$255; used market $200–$350 on eBay.
• Best for: Buyers who found a used unit and prefer Oryx's web-based configuration over a local QMK toolchain.

Verdict: Great board, no longer produced — the EZ is a museum piece in 2026 and warranty service is limited to existing owners.

Drop Planck V6 / V6.1 — first STM32 revision, still occasionally listed via third-party Amazon sellers. Historical MSRP $159; the Drop Planck V6 kit on Amazon appears intermittently. Same grid geometry and QMK/VIA behavior as V7.

Across all Planck variants, the firmware layer system is mandatory. The default keymap reserves two thumb keys for LOWER and RAISE, with ADJUST triggered by chording both. Forty-seven keys cannot cover a full keyboard without layers; this is the defining Planck skill.

Preonic deep dive

The Preonic is what the Planck becomes with one more row. A 12-column, 5-row grid of 60 keys — the same width, 25% taller — that restores a dedicated number row and removes the single hardest part of Planck adaptation.

• Layout: True ortholinear grid.
• Grid: 5 rows × 12 columns.
• Key count: 60 keys.
• Form factor: DIY kit (Drop + OLKB Preonic rev3 / V3).
• Switch compatibility: MX hot-swap via Kailh sockets; supports 2×1u, 1×2u, or 2×2u spacebar configurations.
• Firmware: QMK with community VIA support; STM32 MCU with onboard speaker.
• Connectivity: Wired USB-C.
• Case material: CNC aluminum, historically available in five colors including purple.
• Price: $179–$199 MSRP historically; the Drop Preonic V3 kit on Amazon has shown inflated third-party pricing in 2025–2026.
• Keycap compatibility: Same logic as Planck plus the number row — most "Planck/Preonic" ortho kits cover both.
• Best for: Users who want the ortho philosophy with a gentler adaptation curve, and who find the Planck's number-row-on-layer discipline too demanding for heavy numeric work.

Verdict: The pragmatic ortho choice, but availability in 2026 is the weak link — Drop's shutdown has left the Preonic effectively without an official channel, so buyers are looking at the used market or waiting for possible Corsair restocks.

The Preonic's extra row changes adaptation meaningfully. Without a number row, Planck users must hold LOWER or RAISE for every digit; Preonic users type digits directly, just in a straight column rather than a diagonal shift. For programmers, accountants, or anyone typing numerals regularly, the extra row is worth the height.

XD75: the wide ortho workhorse

The XD75 is the budget warhorse of the ortholinear world — a 5×15 grid of 75 keys, sold as a PCB-only or a la carte kit by KPrepublic (kprepublic.com) and the same vendor's AliExpress storefront. It has been in near-continuous production for most of a decade and remains actively sold in 2026, unlike most of OLKB's catalog.

• Layout: True ortholinear grid.
• Grid: 5 rows × 15 columns.
• Key count: 75 keys (full number row plus three utility columns).
• Form factor: DIY — PCB and case purchased separately; not a single-SKU bundle.
• Switch compatibility: XD75Re has MX hot-swap via Kailh sockets; XD75Am is a soldered MX+ALPS variant.
• Firmware: QMK (official); VIA via community JSON files (not officially supported).
• Connectivity: Wired USB-C or Micro-USB depending on PCB revision.
• Case material: Sold separately — anodized aluminum with acrylic diffuser, stainless steel bent plate, or third-party acrylic.
• Price: PCB from $29.90 on sale (was $57.90); full build typically $150–$210 with switches, keycaps, and case; check KPrepublic's XD75 page for current stock.
• Keycap compatibility: Needs 75 × 1u keys — DSA and XDA blank sets from YMDK are the canonical pairing; YMDK DSA ortho keycap sets on Amazon explicitly target XD75, ID75, Planck, and Preonic.
• Best for: Programmers, power users, and anyone who wants an ortho grid without sacrificing a function row, number row, or navigation cluster.

Verdict: The workhorse choice in 2026 — cheap, widely available, infinitely customizable, and considerably easier to adapt to than a Planck because so few keys move to layers.

A worthy modern alternative is the Idobao ID75, which uses the same 5×15 footprint with official VIA support and better documentation — YMDK sells barebones kits on Amazon in the $150–$170 range (see YMDK Idobao ID75 barebones on Amazon). Buyers who want an XD75 layout with contemporary firmware tooling should prefer the ID75.

Atreus: the column-staggered gateway

The Keyboardio Atreus is included here because it is the board most frequently called "ortho" by people who mean "not row-staggered." It is not ortholinear. It is column-staggered, and that matters — but it also happens to be one of the best gateway boards for people considering the ortho/non-stagger world.

The original Atreus was designed and released as an open-source wooden DIY kit by Phil Hagelberg (technomancy) in 2014, the same year the Planck was born. Forty-two keys, column-stagger, hand-wired. Hagelberg partnered with Keyboardio in 2020 to Kickstart a manufactured 44-key version, and that version is what keyboard.io sells today. The classic wooden kit is effectively retired; Hagelberg's site notes only limited build slots on a wait-list.

• Layout: Column-staggered (NOT ortholinear grid).
• Grid: Approximately 4 rows × 11 columns with vertical column offsets; unified split.
• Key count: 44 keys.
• Form factor: Prebuilt, available as barebones.
• Switch compatibility: MX hot-swap; ships with Kailh BOX switches in multiple options.
• Firmware: Keyboardio Kaleidoscope (Arduino-based) with the Chrysalis GUI configurator; QMK is also fully supported.
• Connectivity: Wired USB-C; no wireless.
• Case material: Anodized aluminum plate; optional walnut palmrest and travel case.
• Price: $149 USD base at keyboard.io in April 2026.
• Keycap compatibility: Ships with XDA-profile PBT; any 1u DSA, XDA, or MT3 set works.
• Best for: Users wanting a portable 40% column-stagger with a prebuilt form factor and no soldering; an excellent "is this style for me?" test.

Verdict: The friendliest entry point into the non-staggered world — not a true grid, but a well-made, honestly priced, and widely loved small keyboard that has converted many users into full column-stagger enthusiasts. A US-side Amazon listing does not currently exist; buyers should order direct from Keyboardio.

Boardwalk, Contra, and other niche ortho

Two frequently cited niche ortho boards deserve a candid update. Neither is in the clean, in-stock state that older guides suggest.

Boardwalk is a 5×14 true-grid ortho designed by shensmobile in 2018 to fit standard 60% cases. In 2026 it is effectively discontinued. The original MKUltra Corporation PCB has been depleted; a planned RP2040 rework never shipped. 1upkeyboards does not carry it. The modern equivalent is the Promenade by Krado Industries, an RP2040-based Boardwalk-compatible design that ran a group buy in January 2024 — that is the path buyers should take today if they want the 5×14 layout.

Contra is a 4×12 through-hole ortho by ai03, originally released in January 2018 under the "Danck" name (renamed after Jack Humbert objected to the Planck-derivative branding). It was deliberately minimalist: bare PCB, FR4 plate, acrylic bottom, no RGB, no underglow. Popular descriptions of "in-switch LEDs and underglow" on the Contra are inaccurate — those features describe the 1upkeyboards Pi40, a distinct RP2040 Planck-alike. The Contra itself is not currently stocked at 1upkeyboards; it is available from KEEBD and Custom KBD at $25–$30 for the kit, and the design is open-source for DIY fabrication.

For readers who specifically want a current-production niche ortho, the 1upkeyboards Pi40 is the honest 2026 recommendation: a Raspberry Pi Pico–based 4×12 grid with per-key RGB, OLED, and QMK/VIA support, sold new and in stock at 1upkeyboards.com. The Boardsource Equals 48 is another true 4×12 option sold directly at boardsource.xyz.

These boards collectively tell a story: the true-grid ortho niche has always been a small and volatile category, and the 2026 production landscape is noticeably thinner than it was three years ago.

Ortho-adjacent split keyboards: Corne, Kyria, Ferris, Helix

The split keyboards that dominate the ergonomic-mechanical conversation in 2026 are almost all column-staggered rather than true ortho, but they descend directly from the same philosophical lineage and are covered here because the transition from a Planck to a Corne is the most common trajectory in the community.

Corne (CRKBD / Helidox) by foostan is the de facto split-ortho standard. A 42-key column-staggered split, 3 rows × 6 columns per half plus three thumb keys. Typeractive sells partially assembled wireless Corne PCBs at $35 per pair; Boardsource sells solderable kits and a fully-assembled wireless SMT variant around $80. Complete builds run $150–$250; the premium aluminum Corne LP can reach $268. Supports MX or Choc v1/v2, QMK/VIA/Vial wired or ZMK wireless.

Kyria by Thomas Baart at splitkb.com is a 50-key column-staggered split with optional encoders and a 128×64 OLED. The current rev3 kit starts around €100 (~$110 USD); the premium Halcyon Kyria rev4 line introduces USB-C interconnect between halves, per-key RGB, pre-soldered hot-swap, and optional LCD/encoder/Cirque trackpad modules at a higher premium tier. QMK, Vial, and ZMK are all supported.

Ferris Sweep by Pierre Chevalier (forked by David Barr) is a minimalist 34-key Choc-only split — five columns, three rows, two thumbs per side. PCBs sell for $18–$30 from Boardsource, Mechboards, Keycapsss, or Kriscables; fully built boards run $150–$250 from Keebmaker, BeeKeeb, or Holykeebs. Typeractive does not carry the Sweep directly in 2026.

Helix by Makoto Kurauchi is one of the few true split ortholinear boards — 5 rows × 6 columns per half plus 2 thumbs, 64 keys total, straight grid on each side. Little Keyboards sells the base PCB kit at $18.99; splitkb offers the premium Aurora Helix revision with per-key RGB and Vial.

These four boards represent the 2026 state of the ergonomic-ortho split market. Buyers drawn to the grid philosophy for ergonomic reasons — wrist relief, reduced ulnar deviation, centered typing posture — will almost always be better served here than by a non-split Planck or XD75. The ZSA Moonlander vs Kinesis Advantage 360 comparison covers the prebuilt high-end column-stagger options for readers unwilling to assemble a DIY kit.

Budget ortho options 2026

A handful of newer 2024–2026 releases have partially filled the gap left by the OLKB / Drop decline. Honest classification matters because most "budget ortho" Amazon listings are actually row- or column-staggered.

Keychron Q15 Max is the strongest name-brand true-grid entry. A 64-key wireless ortholinear released late 2024, CNC aluminum, MX hot-swap, QMK/VIA, tri-mode connectivity. Sold on Keychron Q15 Max via Amazon around $220–$270 in 2026. This is the first mainstream wireless ortho with a polished build and a major brand's warranty.

Epomaker Luma40 is a true 40% ortholinear grid, low-profile Kailh switches, tri-mode wireless, QMK/VIA, hot-swap. The Epomaker Luma40 on Amazon lists around $99–$129. This is the only Epomaker model that qualifies — the Split70 and Split65 are row-staggered despite the "split" branding.

KBDcraft Israfel is a 50% low-profile ortho split with a Lego-style case and Vial support, sold on Amazon around $130.

Several brands frequently mentioned in budget-ortho conversations do not currently make ortholinear boards. Zuoya (GMK67 and variants) is row-staggered 65%, not ortho. NuPhy's entire 2026 lineup — Air V3, Node75, Kick75, WH80 — is row-staggered low-profile despite heavy CES marketing. Royal Kludge and Redragon have no ortho models. A "FormerPhoenix" brand referenced in some aggregator lists does not appear to exist as a real keyboard vendor in 2026.

Mint60 and Mint40 by the Japanese designer eucalyn are column-staggered split DIY kits sold primarily through Yushakobo and TALP Keyboard; they are not on US Amazon and are realistically Japan-market niche products. Buyers shopping Amazon for a true-grid ortho in 2026 have a short honest list: Keychron Q15 Max, Epomaker Luma40, KBDcraft Israfel, and YMDK's Idobao ID75 barebones kits. Everything else labeled "ortho" on the marketplace merits a manual check against the row/column test above.

Firmware essentials: QMK, VIA, Vial, and Oryx

Ortho keyboards without layered firmware are unusable. Forty-seven keys cannot type English without a LOWER/RAISE layer system, so the firmware stack is not a nice-to-have — it is the product. Four tools dominate the 2026 landscape; the keyboard firmware QMK and VIA guide covers the full toolchain in depth.

QMK (Quantum Mechanical Keyboard) is the open-source C codebase Humbert started around the Planck launch and that now supports 3,000+ keyboards. The GitHub repository sits at roughly 20,290 stars and 43,768 forks in April 2026. QMK supports up to 32 layers, tap-dance, mod-tap, combos, macros, auto-shift, and essentially every feature an ortholinear layer design requires. Flashing requires a local toolchain and a command-line build, which is the primary friction point for non-developers.

VIA is a cross-platform GUI that remaps keys live without re-flashing, provided the firmware has VIA support compiled in and a matching JSON layout exists. The Planck V7 ships with VIA/Remap support; the V6, rev6.1, and Preonic rev3 rely on community pull requests that have intermittent maintenance status. XD75 VIA support is community-provided and unofficial. For most users, VIA turns a QMK board from a C-code project into a drag-and-drop configurator.

Vial is a fork of VIA with live editing of tap-dance, combos, macros, and per-key tap/hold behavior. The vial-kb/vial-qmk fork supports Planck, Preonic, Kyria, Corne, Sweep, and many budget ortho clones natively. For ortho users who want to iterate on layer design without flashing, Vial is the 2026 default.

ZSA Oryx is the proprietary cloud configurator for the Planck EZ, ErgoDox EZ, Moonlander, and Voyager. It lives at configure.zsa.io, compiles firmware server-side from a visual layer editor, and produces a .bin flashed via ZSA's Wally tool. Oryx is remarkably polished and a core reason the Planck EZ had such a gentle learning curve for non-programmers — but it is locked to ZSA hardware, which means discontinued Planck EZ units still work but get no new features.

Every Planck or Preonic user should plan to invest a weekend in layer design. The canonical default — QWERTY base, LOWER layer for symbols and media, RAISE layer for numbers and navigation, ADJUST via chord for RGB and firmware utilities — is a useful starting point, not a permanent home.

Keycap compatibility: the biggest challenge

The keycap market is built around row-staggered ANSI layouts, and sourcing a complete set for an ortho board is genuinely harder than ordering keycaps for a TKL. Readers who want the full keycap landscape should work through the keyboard keycaps guide; the ortho-specific rules follow.

The problem is mathematical. A standard ANSI 60% uses a 6.25u spacebar, 2.25u left shift, 1.75u right shift, 1.5u tab, 1.5u backslash, and stepped Caps Lock. A Planck or Preonic uses only 1u keys plus a single 2u spacebar (or two 1u keys replacing it); an XD75 uses 75 × 1u keys, period. Most of the non-1u keys in a standard set are unusable.

The practical ortho buyer needs a kit that includes enough 1u alphas for a 12-column grid (more than the 10-column standard ANSI row supplies), 1u modifiers for Shift, Enter, Backspace, Tab — sizes that do not exist in standard sets — a 2u spacebar (not the 6.25u that comes with every stock set), and, for Preonic, a dedicated number row in 1u.

Three strategies work in practice. First, DSA and XDA profile blank sets from YMDK: flat, symmetrical, all 1u, explicitly marketed for XD75, ID75, Planck, and Preonic. YMDK DSA blank keycaps and YMDK dye-sub ortho sets are the canonical $30–$40 starting points. Transparent and colored ABS variants like YMDK's 81-piece ortho ABS kit are widely available.

Second, sculpted profiles with explicit ortho kits. The Drop + Matt3o MT3 /dev/tty set was the first MT3 release and shipped with a dedicated Ortho Kit for Planck and Preonic, using R4 for the bottom row. Drop's own Acute PBT dye-sub set was designed by Humbert specifically for Planck and Preonic and is the de facto matching companion. Pimpmykeyboard (Signature Plastics) sells DSA and SA profile ortho kits directly.

Third, for GMK or Cherry profile fans, check for an "Ortho Kit" or "40s Kit" on the group buy listing. These add-ons typically bundle 1u modifiers and 2u spacebars sized for Planck, Preonic, and ErgoDox. Without the add-on, a standard GMK base kit will leave the buyer with unusable 1.25u, 1.5u, and 2.25u keys and missing 1u modifiers.

The single most common costly mistake is ordering a "compatible" GMK set without verifying ortho kit inclusion. Check the keycap count, the specific unit sizes listed, and whether the bottom-row profile works on a grid before committing.

Who should (not) get an ortholinear keyboard

The population that benefits most from ortho is narrow and honest identification matters. A disciplined touch typist who consistently uses correct finger-to-column assignment, is willing to tolerate 2–6 weeks of reduced output, and either values the geometric cleanness aesthetically or programs heavily in a home-row-biased environment is the ideal ortho buyer. Programmers who use Vim, Emacs, or any heavily keyboard-driven IDE often find that layered symbols and home-row mods on a Planck genuinely improve throughput after adaptation. The best keyboards for programming and developers guide covers the software-side workflow fit.

The populations that should not start with a non-split ortholinear are larger and more commonly misadvised. Typists primarily seeking wrist pain relief should look at split column-staggered boards (Corne, Kyria, Moonlander, Advantage 360) rather than a Planck — a flat, centered grid does not fix ulnar deviation. Heavy gamers who rely on WASD, QWE muscle memory, and quick panic-keybind presses will find ortho re-training disrupts the non-typing finger reflexes that matter for competitive play. Users who share their keyboard with coworkers, family, or guest-access hardware will find a 47-key Planck with layered symbols effectively unusable to anyone else. Hunt-and-peck typists are learning two things at once — touch typing AND grid geometry — and would be better served learning touch typing first on a normal keyboard, then considering ortho after.

The most defensible middle path for curious users is a 75-key XD75 or Idobao ID75. The full number row, dedicated nav keys, and retained modifier column make it possible to evaluate the grid feel without simultaneously learning a 40% layer system. If the XD75 experiment feels good after a month, graduating to a Planck or Preonic becomes a much smaller step.

How to choose your first ortho

Four questions narrow the field quickly.

First, DIY or prebuilt? Prebuilt buyers have essentially two current choices: the Keyboardio Atreus at $149 (column-staggered, gentle intro) or the Keychron Q15 Max at $220–$270 (true grid, wireless, warranty). DIY buyers have the entire ecosystem open — Planck V7 kits when restocked, XD75 from KPrepublic, Idobao ID75 on Amazon, or Pi40 from 1upkeyboards.

Second, how many keys? 75 keys (XD75, ID75) for the easiest adaptation. 60 keys (Preonic) for number-heavy work. 48 keys (Planck, Contra, Pi40) for the full minimalist experience. 40 or fewer for experienced users only.

Third, split or unified? If wrist pain is a motivator at all, pick a column-staggered split (Corne, Kyria, Ferris) over a non-split grid. A non-split ortho is an aesthetic and workflow choice, not an ergonomic intervention. The split keyboard ergonomic guide and the Alice layout guide cover the intermediate options for readers who want some wrist splay without the full split commitment.

Fourth, how much firmware are you willing to configure? Oryx (Planck EZ) is point-and-click but requires hardware you can no longer buy new. VIA (Planck V7, Q15 Max, Luma40, Atreus) is a GUI with live remapping. Vial (Corne, Kyria, Pi40, Idobao) adds tap-dance and combo editing. Raw QMK (XD75, older builds) requires a local toolchain. The firmware ladder runs roughly in that order of increasing difficulty.

For most first-time ortho buyers in 2026, the practical recommendation is a Keychron Q15 Max if prebuilt and premium, an Epomaker Luma40 if budget low-profile, an Idobao ID75 if DIY and grid-committed, or a Keyboardio Atreus if a column-staggered prebuilt is acceptable. The canonical Planck experience remains available only to those willing to chase secondary-market stock.

Price and where to buy

The 2026 buying landscape reflects the Drop closure and the OLKB production decline. Direct vendors in the US ecosystem break down as follows.

ZSA at ergodox-ez.com continues to sell the Moonlander, Voyager, and ErgoDox EZ; the Planck EZ is discontinued. Corsair's retail.corsair.com subsite inherited select Drop products including Planck V7 kits at $129, though stock is thin. 1upkeyboards.com sells the Pi40 and the Zlant ortho lines. KPrepublic remains the primary XD75 source with PCBs from $29.90. Keyboardio sells the Atreus at $149 and has introduced a newer Preonic-branded ortho model. Boardsource ships Corne, Ferris Sweep, and Equals 48 kits from Las Vegas. Typeractive focuses on Corne and Lily58 builds. splitkb.com in the Netherlands is the Kyria and Aurora-series source.

Amazon US affiliate listings cover a narrower but useful slice: the Keychron Q15 Max, Epomaker Luma40, KBDcraft Israfel, and YMDK Idobao ID75 barebones kits are the main prebuilt and kit options. DIY-support purchases — YMDK DSA blank ortho keycaps, a Kemove 2-in-1 switch and keycap puller, a Pinecil portable soldering iron for through-hole builds like the Contra or Helix, and a Cherry MX switch sampler for pre-purchase switch testing — complete the toolkit. A broader Amazon sweep is also available via the ortholinear keyboard search on Amazon. Builders planning longer DIY journeys should consult the custom keyboard building guide and the first custom keyboard build guide for the full assembly workflow.

Pricing bands for 2026 plan on the following approximate ranges: Planck kits $129–$159 (when in stock), Preonic kits $179–$199 (rare), XD75 full builds $150–$210, Atreus $149 prebuilt, Corne kits $100–$250, Ferris Sweep $50 PCB to $250 built, Helix $80–$150 complete, Contra $25–$30 kit, and Keychron Q15 Max $220–$270 prebuilt. Shipping from Asia (KPrepublic, AliExpress) often adds 7–14 days and variable customs. European vendors (splitkb, Keycapsss) typically adjust VAT at checkout for US buyers.

FAQ

Conclusion

Ortholinear is a coherent design philosophy with a real historical grievance — the 1878 row-stagger is genuinely a mechanical artifact — but it is not a universally better keyboard layout. The grid's appeal is geometric regularity and layered workflow discipline, not ergonomic supremacy; anyone whose primary motivation is wrist relief should be looking at column-staggered splits like the Corne or Kyria rather than a non-split Planck. The honest 2026 verdict is that ortholinear rewards users who value column-aligned finger travel, enjoy firmware tinkering, and are willing to absorb a meaningful multi-week adaptation cost, and that it disappoints users who expect it to automatically fix typing problems created by posture, tilt, and board position.

The OLKB ecosystem that defined the category has thinned considerably. Drop closed in March 2026, the Planck EZ was retired in 2023, and olkb.com itself is dormant. In practical terms, a buyer walking into the ortholinear category in 2026 is choosing between a small number of active-production options: Keychron's Q15 Max for mainstream wireless grid typing, Epomaker's Luma40 for low-profile budget entry, KPrepublic's XD75 for the classic DIY workhorse, Idobao's ID75 for a modern VIA-compatible clone, and the Keyboardio Atreus for the column-staggered gateway. The Planck and Preonic remain available primarily through secondary markets and sporadic Corsair restocks. The community has largely moved into the split column-staggered universe, where genuine ergonomic gains are available at the cost of DIY assembly.

The practical recommendation for a curious first-time buyer is almost always to start with a 75-key grid (XD75, ID75, or Q15 Max) rather than a 40%, and to treat the adaptation period as a serious investment rather than a weekend experiment. Users who complete the transition and find they prefer the grid can graduate to a Planck later with relatively small additional friction. Users who discover after a month that the grid is not for them have lost much less time and money than if they had started with a $220 Planck EZ used unit and a matching MT3 set.

Ortholinear in 2026 is a mature, niche, honest design philosophy — not the future of typing, not the answer to every wrist problem, but a legitimate and rewarding tool for the typists it suits. Approached with realistic expectations and the right first board, it is one of the most satisfying changes a keyboard enthusiast can make. Approached as a silver bullet, it is an expensive disappointment. The difference between those two outcomes is almost entirely the reader's — and this guide's job has been to make the choice an informed one.
