These keyboards are available in various sizes. We bought and tested the NuPhy Halo96, which has a compact (96%) form factor, but a smaller compact (75%) Halo75 and a compact 65% Halo65 are also available. You can see the listed dimensions of these other size variants on NuPhy’s website.
The NuPhy96 has nearly all the keys on a typical full-size keyboard but in a more compact package. This keyboard has conventional spacing between keys, so typing doesn’t feel cramped. However, it doesn’t have space between key zones, like the navigation cluster, arrow keys, or the Numpad. While this keyboard is smaller than most full-size options, it’s also quite heavy and not very portable.
