Full-Size vs. TKL Keyboards: Which Should You Buy?
The most common keyboard size decision is full-size versus tenkeyless (TKL). Both layouts include arrow keys, function keys, and a full navigation cluster — the only difference is the numpad. That single difference, however, changes how much desk space the keyboard occupies and how you position your mouse. Here is what to consider before you choose.
Full-Size vs. TKL: Side by Side
| Feature | Full-Size (100%) | TKL (87%) |
|---|---|---|
| Numpad | Included — 17 dedicated number and operator keys on the right side | Not included — the right side ends after the arrow key cluster |
| Total keys | ~104 keys | ~87 keys — the numpad rows account for the difference |
| Desk footprint | Full width — typically 440–450 mm wide | Shorter — typically 360–370 mm wide, freeing around 80 mm on the right |
| Mouse placement | Mouse sits further right, increasing shoulder reach during gaming or mousing | Mouse sits closer to the keyboard, reducing shoulder strain during extended use |
| Navigation keys | Full navigation cluster: Insert, Delete, Home, End, Page Up, Page Down — all dedicated | Same dedicated navigation cluster — nothing is removed beyond the numpad |
| Function row | Full F1–F12 row with no compromises | Full F1–F12 row — identical to full-size |
| Data entry and number input | Excellent — numpad makes rapid number entry fast and accurate | Requires the top number row for all digit input, which is slower for repetitive entry |
| Gaming | Functional, but the wider layout pushes the mouse further right | Preferred by many gamers — more central mouse position and better ergonomics |
Who Should Choose Each
Full-Size is a good fit if:
- ✓Finance, accounting, or any role requiring frequent numpad use
- ✓Spreadsheet-heavy workflows where the numpad speeds up data input
- ✓Desktop setups with ample desk space where size is not a constraint
- ✓Users who also need dedicated Home, End, and navigation keys with no trade-off
- ✓Gamers who actively use the numpad for macros or in-game commands
TKL is a good fit if:
- ✓Gamers who want the mouse closer to center without sacrificing function keys
- ✓Mixed-use setups where typing and mousing alternate throughout the day
- ✓Compact or shared desk spaces where desk real estate matters
- ✓Users who rarely or never use the numpad in daily tasks
- ✓Anyone who wants a cleaner desk appearance without going to a smaller layout
Frequently Asked Questions
- Is TKL better for gaming than full-size?
- For most gaming setups, TKL offers a practical advantage: removing the numpad lets you position the mouse closer to your keyboard, reducing the angle your shoulder and arm hold during play. Whether that matters depends on how much desk space you have and how far you move the mouse during gaming. If you actively use the numpad for macros or in-game controls, a full-size board is the better choice.
- Can I add a numpad to a TKL keyboard later?
- Yes. Standalone USB numpads are widely available and connect via USB to any computer. This gives you the numpad when you need it and lets you move it aside when you do not. Some enthusiasts use a separate numpad positioned on the left side of the keyboard for a more ergonomic layout.
- Does TKL sacrifice any function keys or navigation keys?
- No. A standard TKL keyboard keeps the full function row (F1–F12), the navigation cluster (Insert, Delete, Home, End, Page Up, Page Down), and all arrow keys. The only keys removed are the 17 numpad keys on the right side.
- Which is better for office and typing work?
- For general office work without heavy number entry, TKL works just as well as full-size and often feels more comfortable because it allows a more natural arm position. For roles involving frequent numpad use — accounting, data entry, stock trading — full-size is the more efficient choice.
- Are TKL keyboards more portable?
- They are shorter, which helps when fitting a keyboard into a laptop bag or switching between workstations. However, most TKL keyboards are still desktop peripherals with standard key profiles, not designed for regular travel. If portability is a primary concern, 65% or 60% layouts offer a smaller footprint.
- Do full-size and TKL keyboards use the same switches and keycaps?
- Yes. Both layouts use standard mechanical or membrane switch types and standard keycap sizes for all shared keys. The keycap legends and switch actuation are identical — only the layout and total number of keys differ. This means most keycap sets and custom switches are compatible with both.
