Keychron V4 vs V660% vs Full-Size Layout Comparison

The core difference is the layout size. The V4 is a 60% keyboard, missing the number pad, function row, and navigation cluster. The V6 is a full-size 100% keyboard that includes all these keys. This fundamentally changes the desk footprint and typing experience.

Yes. Both the Keychron V4 and V6 feature hot-swappable PCBs. According to their product listings, they support both 3-pin and 5-pin mechanical switches, allowing for easy switch changes without soldering.

Yes, both keyboards support full programmability. They are compatible with the open-source QMK firmware and the VIA configurator, allowing for deep key remapping, macro creation, and layer configuration directly from a web app.

The Keychron V4 is significantly better for small desks. It measures 304mm in length and weighs 730g, taking up minimal space. The V6 is 448mm long and weighs 1360g, requiring a much larger and more permanent desk area.

Yes. Both keyboards list Mac and Windows support. Their product descriptions mention they include a system toggle switch and an additional set of keycaps for both operating systems, allowing you to save separate layouts.

Both the V4 and V6 fully assembled versions come with double-shot PBT keycaps in the OSA profile. The manufacturer states these are non-shine-through keycaps designed for oil resistance and durability.

Both models use screw-in PCB stabilizers. The product descriptions highlight that this design increases stability for larger keys like the spacebar and shift, and both support third-party screw-in stabilizers for modding.

Yes. The vendor page for the V6 lists 'Fully Assembled Knob' and 'Barebone Knob' as purchase options. The V4 listing also shows 'Knob Support' as a feature, suggesting potential compatibility or a separate version.

Both feature south-facing RGB LEDs, which prevent interference with Cherry-profile keycaps and provide better backlighting from the typist's angle. The V6 listing additionally mentions a 'White' LED option, but both share the same core RGB technology.

According to the manufacturer's description for both models, the included Keychron K Pro switches (excluding clicky versions) are factory pre-lubed. This is intended to provide a smoother typing experience straight out of the box.

Yes. Both the Keychron V4 and V6 are available as barebone kits. These kits include the ABS case, PCB with screw-in stabilizers, and steel plate, but do not include keycaps or switches, allowing for a fully custom build.
