Compare Keychron Q0 vs Q3 Differences Side by Side

This comparison is for buyers deciding between a dedicated numpad and a full tenkeyless keyboard. The decision is hard because both are high-quality, customizable Keychron options with aluminum cases and QMK/VIA support, but they serve completely different roles. The Q0 is a standalone numpad ideal for adding to an existing setup, while the Q3 is a complete 80% keyboard with a more advanced double-gasket mount and a programmable knob. Your choice depends on whether you need a full keyboard or just a numpad.

Pros and Trade-offs

For users who need a complete keyboard with advanced features like a double-gasket mount, programmable knob, and multi-media keys, the Keychron Q3 is the better choice. If you already have a keyboard and only want a high-quality, customizable numpad with PBT keycaps, the Keychron Q0 fills that specific niche well. The Q3 offers more versatility, while the Q0 is a specialized add-on.

Keychron Q0

  • +Dedicated standalone numpad that can be moved aside to save desk space.
  • +Compact dimensions (20 x 129 x 89 mm) and lighter weight (500g) for a numpad.
  • +All-metal CNC machined 6063 aluminum body with screw-in PCB stabilizers.
  • +Includes double-shot OSA PBT keycaps for better oil resistance and legend durability.
  • −Tray mount design, which is less advanced for sound and feel compared to gasket mounts.
  • −No dedicated knob or multi-media keys for macros or volume control.
  • −Sold as a numpad only, not a full keyboard, requiring a separate keyboard to use.

Keychron Q3

  • +Double-gasket design with silicone pads to reduce metal resonance and improve typing sound.
  • +Programmable aluminum knob for custom macros like zoom, volume, or brush size.
  • +Full 80% keyboard with Mac/Win system toggle and compatible keycaps for both OSes.
  • +Offers multiple layout options including ANSI and several ISO variants.
  • +Sound dampening included for a quieter typing experience.
  • −Heavier and larger at 2000g and 365 mm length, less portable than smaller boards.
  • −Comes with ABS keycaps on fully assembled versions, which may wear faster than PBT.
  • −Wired-only connectivity limits placement flexibility compared to wireless options.

Which Keyboard Is Better for Your Needs?

The Q3 wins for gaming, office, modding, and content creation due to its full keyboard layout, double-gasket design, and programmable knob. Both keyboards tie for programming and travel, as they share QMK/VIA support and wired-only connectivity, with the Q0 being smaller but incomplete. If your priority is a complete keyboard with advanced features, the Q3 is the clear choice.
