You’ve just unboxed a beautiful new set of keycaps—only to discover the spacebar doesn’t fit your keyboard. Don’t worry, you’re not alone. In fact, this is one of the most common frustrations in the mechanical keyboard hobby. Here’s what you need to know to avoid mismatches and make the most of your setup.
1. Understand Spacebar Sizes
Not all keyboards use the same spacebar size. The two most common sizes are:
6.25u – standard on most ANSI layouts
7u – more common on vintage or custom layouts
There are also rarer variants like 6u or split spacebars (3u + 3u, etc.).
How to check yours: Measure the spacebar in “u” units (1u = width of a standard key like Esc). A 6.25u spacebar spans the length of 6.25 normal keys.
2. Bottom Row Layout Matters
Aside from the spacebar itself, the entire bottom row can vary:
Standard layout: 1.25u modifiers (Ctrl, Alt, Win), 6.25u spacebar
Non-standard layout: 1u or 1.5u modifiers, 7u spacebar
Layouts like Razer, Corsair, or 75% keyboards often use custom bottom rows. Always check before purchasing keycaps.

3. Fixes & Workarounds
Still want to use that keycap set?
Mini sets: Replace only the incompatible keys. Our Mini Set (4pcs) includes a spacebar and essential mods.
Artisan upgrades: Swap your spacebar with a metal artisan for contrast and fit.
Customize: Some brands (like Awekeys) provide compatibility support or even customized pieces if requested.
Bonus: We offer custom services to help you solve wobbly stem issues and size mismatches. If you're running stiffer or custom-weighted springs, consider upgrading to our Awekeys V1 Switches—designed for tighter stem grip and optimal pairing with metal caps.
4. Plan Ahead with Compatibility Tools
Use tools like:
Keyboard Layout Editor – to visualize your board
Keycaps.info – to compare keycap set compatibility
These external sources make planning your build easier and more accurate.
