40% Keyboards

40% keyboards drop the number row and arrow keys for an ultra-compact footprint, with every function still reachable through layers. Here you'll find both finished boards and kits to build – ideal if you want to save desk space and run a minimalist setup.

40% keyboards: ultra-compact with layers

A 40% keyboard drops the number row along with the numpad. Numbers, symbols, function keys and arrows live on layers. You activate them with a held or tapped key.

Which layouts are there?

Staggered: offset rows like a normal keyboard, just without the number row.
Ortholinear: keys in a grid, for example 12×4.
With extra keys: some layouts keep individual keys, such as the numbers 1–6 at the top left.

A split spacebar is common because the second half often serves as a layer key.

Who is it for?

For anyone short on space, who wants to keep their hands still or likes a minimalist setup. Two to three layers are usual: one with numbers and symbols, one with arrows, navigation and media keys. You define the mapping in the firmware. Plan for some time to get used to it.

Keycaps and accessories

Regular keycap sets often do not fully cover a 40% board. Look for a 40s kit in the set. How layouts and kits fit together is explained in the guide Keyboard sizes and layouts. If you want a few more keys, take a look at the 60% keyboards. A 40-percent keyboard is not the default choice for beginners: the community maintains guides of its own, and you learn the layers best step by step. In return you get short finger travel.
