Keyboard sizes are written as percentages of a full-size keyboard. Smaller percentages drop keys to free up desk space (and let your mouse hand sit closer to your body). The trade-off is functionality you have to access through key combinations, called layers. Picking a size is the single biggest decision in choosing a keyboard.
Full-size (100%)
Everything: alphas, modifiers, function row, arrow cluster, navigation cluster (Home/End/PgUp/PgDn/Insert/Delete), and a numpad. Around 104 keys (ANSI) or 105 keys (ISO).
- Pros: Every key has a dedicated home. Best for heavy data entry, accounting, spreadsheets.
- Cons: The numpad pushes the mouse far to the right, forcing a wider shoulder angle. Most ergonomists recommend a smaller board for daily comfort.
- Examples: Corsair K70, Logitech G915, most stock office boards.
TKL — tenkeyless (87 / 88 keys)
Full-size minus the numpad. Keeps the function row, arrow keys, and navigation cluster. The classic gaming keyboard size for two decades — most pro FPS players use a TKL.
- Pros: Familiar — nothing is moved to a layer. Brings the mouse closer to the body.
- Cons: Still 14 inches wide. If you ever need a numpad, you'll miss it (separate USB numpads are cheap solutions).
- Examples: Logitech G PRO X TKL, Razer Huntsman V2 TKL, Keychron Q3, almost any premium custom 80% board.
75% (84 keys)
TKL with the navigation cluster and function row compressed into the body of the board. Looks like a TKL with everything squished left. The most popular enthusiast size in the last two years.
- Pros: All TKL keys present, but the board is 1–2 inches narrower. Best balance of functionality and desk space.
- Cons: Arrows are tucked under the right shift, which takes a day to adjust to. Some 75% boards drop one key per row to fit.
- Examples: Keychron Q1 / K2, GMMK Pro, NuPhy Air75, Womier S-K71.
65% (68 keys)
Drops the function row and most of the navigation cluster, but keeps arrow keys and 4–5 navigation keys (usually Delete, Home, End, PgUp, PgDn).
- Pros: Compact and arrow-positive. Most everyday users can adapt within a week.
- Cons: Function row lives on a Fn layer — typing Alt+F4 becomes Fn+4 (or whatever the layout assigns).
- Examples: Keychron K6 / K7, Akko 3068, Razer Huntsman Mini... wait, that's 60%. Akko ACR68 then.
60% (61 keys)
Alphas, modifiers, and that's it. No arrow keys, no function row, no nav cluster. Everything except letters lives on layers.
- Pros: Tiny — fits in a backpack pocket. Forces clean ergonomic positioning.
- Cons: Steep adjustment curve. Need to learn (or remap) Fn combinations for arrows, function row, Esc — many 60% boards use Caps Lock as a layer key.
- Examples: Razer Huntsman Mini, Anne Pro 2, Ducky One 2 Mini (the board that launched a thousand colored cables).
40% (~46 keys)
Alphas and the bare minimum of modifiers, with two or three layer keys to access everything else. Numbers live on a layer. So do symbols. This is a deep hobby commitment.
- Pros: Almost no hand movement; the most ergonomic 'reach to anything' of any board.
- Cons: Months of muscle-memory rebuilding. Numbers especially feel awkward early on.
- Examples: Vortex Core, JJ40, Planck (ortholinear), the entire community around r/40percentclub.
Beyond percentages
Alice / ergo boards
The keyboard is split into two angled halves and joined in the middle, putting the wrists at a more natural angle. Famous examples: TGR Alice, Keychron Q8, Lily58 (split), Glove80, ZSA Moonlander.
Split keyboards
Two physically separate halves connected by a cable or wireless link. Best ergonomics — you can place each half exactly where your shoulders want. Steeper learning curve and usually programmable column layouts.
Ortholinear and column-staggered
Most keyboards are row-staggered — each row offsets by half a key, a holdover from typewriter mechanics. Ortholinear keyboards have keys in a perfect grid; column-staggered keyboards (like the Glove80) offset each column to match finger lengths. Both feel deeply unfamiliar at first and very natural after a few weeks.
Layers — how small boards stay usable
On a small board, the unmapped functions live on a layer accessed by holding a layer key (Fn, Caps Lock if remapped, etc.). Hold the layer key + a letter and you get a function row key, a nav key, an arrow, whatever the firmware assigns.
- Most modern boards are programmable with QMK, VIA, or vendor software. You can move anything anywhere.
- A common 60% layout: Fn+1–= for F1–F12, Fn+IJKL for arrows, Fn+UO for Home/End.
- Some boards have multiple layers — Fn for one, a different layer key for another. Stenographers use 4+ layer boards routinely.
Which to buy
| You are | Recommended size |
|---|---|
| A first-time mechanical buyer, office worker | TKL or full-size |
| A casual gamer / typist who wants something smaller | 75% or 65% |
| An FPS player aware of mouse-arm ergonomics | TKL, 65%, or 60% |
| An MMO / RPG player who uses lots of keys | Full-size or 75% |
| A heavy data-entry / accountant | Full-size, or TKL + separate numpad |
| Someone curious about the hobby | 75% — most modern enthusiast boards live here |
| Someone with wrist pain | Alice, split, or low-profile keyboard at shoulder width |
