Understanding Keyboard Measurements

Before diving into the different keyboard sizes, let’s briefly discuss how they are measured. Keycap width is measured in ‘u’, with a typical keycap being approximately 19mm in width. This unit of measurement will help you understand the dimensions of various keyboards.

Full-Size Keyboards (104-108 keys)

Full-size keyboards typically host between 104 to 108 keys and span roughly 22.5u or 427.5mm in width. These keyboards afford a comfortable typing experience, with dedicated keys for number input, navigation, and the function row. However, full-size keyboards can be somewhat cumbersome and pricier. For further information on full size keyboards, refer to our article about tkl vs. full size keyboards.

Compact Keyboards: A Closer Look

Compact keyboards save desk space while still offering a majority of the functionality found in full-size keyboards. Let’s explore two popular compact options: the 1800 Compact and the 96% keyboard.

1800 Compact (96%)

The 1800 Compact shaves off 3.75u from a full-size keyboard’s width by relocating the navigation cluster above the numpad and squeezing the numpad closer to the left. Measuring at 18.75u wide, these keyboards are rarer and require unique keycap sizes. They offer a space-saving option without sacrificing much functionality.

96% Keyboard

Nearly the same as the 1800 layout, the 96% keyboard eliminates gaps and measures 19u wide. This design saves about 0.25u of width compared to an 1800 keyboard, providing a similar space-saving benefit.

Tenkeyless (TKL) Keyboards (80% or 87 keys)

Tenkeyless keyboards, also known as 80% keyboards, measure 18.25u wide and are popular among gamers and streamers. These keyboards lack a numpad but retain the function row, arrow cluster, and navigation keys. TKL keyboards are a great option for those who don’t require a numpad for heavy number processing.
