Compare Keychron V2 vs V4 Differences Side by Side

This comparison is for buyers deciding between Keychron's two most compact wired custom keyboards. The choice is difficult because both the V2 and V4 share nearly identical core features like QMK/VIA programmability, hot-swap sockets, and screw-in stabilizers. The decision ultimately hinges on whether you prioritize the extra functionality of a 65% layout or the extreme minimalism of a 60% form factor, as the price and core customization experience are very similar.

Pros and Trade-offs

Your choice between the Keychron V2 and V4 is a direct trade-off between functionality and footprint. If you use arrow keys frequently for work, gaming, or coding and want the option of a programmable knob, the V2 is the clear choice. If your priority is the smallest possible keyboard and you are comfortable using layers for arrows, the V4 delivers the same high customizability in a more minimal form. For all other aspects of the custom keyboard experience, these two models are virtually identical.
