Keyboard Sizes Compared: Full-Size, TKL, 75%, 65%, 60%

Keyboard size comparison works best when you compare actual boards. A percentage tells you roughly which keys remain, but it does not give you a case width or guarantee that two keyboards arrange their navigation keys alike.

This guide uses models in our 41-board database to connect layout names with published dimensions and practical compatibility checks. Start with the table below, then compare keyboards side by side to check the other specifications of your shortlist. The dimensions are manufacturer figures, not measurements made by this editorial desk.

Keyboard sizes, key counts and physical width bands

The key counts below describe common conventional layouts, with variation for regional layouts, knobs and extra controls. The width bands are rounded planning bands around the named examples, not minimum and maximum widths for every keyboard in that class. Here, width means the left-to-right desk footprint; some manufacturers call that dimension length.

Size	Usual key-count guide	Planning width band	Named database example and published width	Keycap-kit check
Full-size / 100%	About 104-108	440-450 mm	Keychron V6: 447.85 mm	Full numpad, wide modifiers and any extra top-row keys
TKL / 80%	About 87-88	360-370 mm	Keychron Q3: 365.1 mm	Correct Enter shape, Shift keys and bottom row
75%	Often about 81-84	310-320 mm for the K2 example	Keychron K2 V2: 313 mm plastic frame; 317 mm aluminum bezels	Short right Shift and the correct navigation-row caps
65%	Often about 66-68	310-320 mm for the K6 example	Keychron K6: 313 mm plastic frame; 317 mm aluminum bezels	Right Shift, small right-side modifiers and navigation keys
60%	Commonly 61-62; special layouts vary	300-310 mm	Wooting 60HE product page: 302 mm	Exact bottom row and regional layout; do not assume HHKB coverage

Keychron’s V6, Q3, K2 and K6 product pages supply those dimensions. Wooting’s linked page now describes the 60HE+ within the 60HE family; its 30.2 cm dimension converts to 302 mm. The comparator retains an older 60HE model label, so confirm the exact revision before treating the page as a specification for a used board.

The table also exposes a useful limit of percentages: the plastic-frame K2 and K6 are both 313 mm across despite their 75% and 65% labels. Removing the function row changes the front-to-back arrangement, not necessarily the left-to-right footprint. Do not calculate case dimensions by multiplying a full-size width by 0.75 or 0.65.

What the comparator’s layout fields actually tell you

The comparator has separate Layout and Size % rows. Layout is the more useful starting filter: it groups familiar arrangements such as 75%, TKL and full-size. Size % is a stored label rather than a measured desk-space ratio. Neither row contains case dimensions, and neither should substitute for a manufacturer’s dimensional drawing.

The database includes several models within a size, so you can hold layout roughly constant while comparing switch options, hot-swap support, connectivity, mounting and software. A comparison between different sizes answers another question: which physical keys would you exchange for space? Use both approaches before deciding that a smaller board is automatically the better fit.

For a concrete start, compare 75% keyboards by layout. The Size filter opens on 75%, while the list remains available for selecting two or three models. Change it to another size to explore neighboring layouts. Selection is separate from filtering, so check the selected count before generating your table.

Full-size: keep the dedicated number pad

Full-size gives numeric entry its own cluster alongside the alphanumeric keys, function row, arrows and navigation keys. The V6 is the full-size reference in the table; other full-size records in the dataset include the Ducky Shine 7 and Corsair K70 RGB Pro.

Choose this arrangement if the number pad is part of your normal workflow. If it is only occasional, compare the physical width with a TKL before paying for space you seldom use. This is a workflow trade-off, not a claim that one layout improves typing speed or comfort for everyone.

A full-size keycap purchase needs numpad coverage as well as the main typing area. Check the numpad zero, Enter and plus keys on the kit diagram, then check any extra keys above that cluster. A large total cap count does not by itself establish compatibility with the specific keyboard.

96% and 1800: a separate compact-numpad option

The database also contains a 96% / 1800 filter, including the Keychron K4 V2 and Glorious GMMK 2 96%. These arrangements retain a number pad while compressing the separation between clusters. Keychron describes the K4 V2 as a 100-key keyboard; that is a model specification, not the definition of every 96% layout.

This is worth comparing with full-size if you want numeric entry but need a narrower arrangement. Look closely at where the arrows meet the number pad and which navigation keys remain dedicated. The physical grouping is part of the choice: keeping a key somewhere on the board is different from keeping it in the position you already use.

For keycaps, inspect the actual bottom row and numpad layout instead of ordering a kit solely because its listing says full-size compatible. Compact numpad designs can rearrange modifiers and navigation keys, and the layout image is the appropriate reference for those details.

TKL: remove the numpad, preserve the main clusters

Tenkeyless removes the dedicated number pad while keeping a separate function row, arrows and navigation block on a conventional arrangement. The Q3 supplies the table’s dimensional reference; the dataset also lists the Keychron K8, Ducky One 3 TKL and several other TKL designs.

TKL is a useful comparison baseline when you rarely enter long strings of numbers. It lets you evaluate the space saved by removing one distinct cluster without also moving the function row onto a layer. Check the individual layout if a media control or knob replaces a key.

The Q3 and V6 examples differ by 82.75 mm in published horizontal size. That subtraction describes these two cases, not a guaranteed saving for every full-size-to-TKL switch. Bezels, controls and case design still contribute to the total. Mark out the actual widths on your desk if the available space is close.

75%: keep the function row in a tighter arrangement

A 75% generally combines a function row and dedicated arrows with a compressed navigation area. It need not retain every key from a conventional TKL. Check Delete, Home, End, Page Up and Page Down individually if your work depends on them.

The K2 V2 is the table’s reference, while the comparator also includes the Keychron Q1 family, Keychron V1, NuPhy Air75 V2 and other 75% boards. Their shared layout label does not promise identical case dimensions, switch height or keycap compatibility.

Keychron’s size charts are useful here because they show the key widths and positions that a kit must cover. A shortened right Shift and row-specific navigation caps deserve particular attention. With a sculpted keycap profile, the right printed legend on the wrong row can still be the wrong physical cap. Use the chart for the exact model and layout.

65%: keep arrows, put the function row on a layer

A conventional 65% keeps dedicated arrows and some navigation keys while removing the separate F1-F12 row. The K6, Ducky One 3 SF and several custom kits are examples in the database. The practical question is how often you need a function key while holding other modifiers.

Write down the combinations you use for editing, shortcuts or games before choosing this size. Then read the manufacturer’s key-combination table. A missing dedicated F5 key can be acceptable if its layer position suits your hands, but the percentage label does not tell you where that position is.

The K6 also illustrates why model variants matter. Its manufacturer distinguishes mechanical, hot-swappable and optical options. A layout match does not prove switch compatibility. Read the comparator’s Switch options alongside Hot-swap, and use the hot-swap vs soldered comparison before buying replacement switches.

60%: verify how navigation works

A conventional 60% removes the separate function row, navigation block and dedicated arrow cluster. The functions can remain available through layers or remapping, but the exact bindings belong to the keyboard’s firmware and keymap.

The database includes the Wooting 60HE family, Corsair K65 RGB Mini, Anne Pro 2 and a separate HHKB layout label. Treat HHKB as a distinct arrangement when checking modifiers and keycaps. The same broad size class does not imply the same switch stem, bottom row or replacement-cap kit.

QMK’s layer documentation explains how a supported keyboard can expose another set of key actions while a layer is active. That is a capability to verify on the chosen board, not a promise that every compact keyboard runs QMK. The comparator’s Software row helps identify which configuration system you need to investigate.

Check the keycap kit against the board, not the percentage

Use Keychron’s model-specific keycap charts as an example of the evidence to look for. Compare the keyboard diagram with the kit diagram, paying attention to Enter shape, both Shift keys, the spacebar, right-side modifiers and navigation rows. Include numpad keys if the board has them.

Keep three checks separate: the cap must attach to the switch stem, have the right width, and belong to the right row when the profile is sculpted. A kit advertised as covering 75% keyboards may cover one model’s arrangement and omit a cap needed by another. A 60% label is equally insufficient for special layouts.

This article uses those checks to compare whole keyboards. It does not attempt to catalogue every keycap profile or dimensional tolerance. The source diagrams and the exact kit’s coverage image are the final references for a purchase.

Build a shortlist in three passes

First, choose the key clusters you need without a layer: number pad, function row and arrows. Second, verify the actual case width and depth for the precise model revision, allowing room for the cable and any wrist rest you plan to use. Third, compare the remaining specifications.

Use the keyboard comparator for that final pass. Pair this size check with the linear, tactile and clicky comparison, the Hall effect comparison if adjustable actuation matters, and membrane vs mechanical keyboards if you are still choosing the underlying keyboard type.

A useful result is a small set of boards whose layout, dimensions and configuration requirements you understand. The smallest percentage is not an objective winner; the appropriate size is the one whose retained keys and physical footprint match your constraints.
