Compare Keychron K4 Max vs V6 Max Differences Side by Side

This comparison is for buyers who want a full numpad but are torn between saving desk space and having a traditional full-size layout. The decision is tricky because both keyboards share the same core connectivity, excellent wireless performance, and QMK/VIA programmability. However, they differ significantly in their physical layout and internal build philosophy. The K4 Max is a dense 96% board with a steel plate and PCB-mount design, while the V6 Max is a larger 100% board with a gasket mount and polycarbonate plate for a softer feel.

Pros and Trade-offs

For buyers who value desk space and a dense layout, the Keychron K4 Max is the better choice, as it packs a full numpad into a smaller footprint with a solid, responsive feel from its steel plate. For those who want the best typing comfort and office features, the Keychron V6 Max wins with its gasket mount, quiet operation, and a very practical knob. If you want to build your own keyboard from the ground up, the V6 Max's barebones option is a major advantage.
