Keycap Profiles Explained
If you've been shopping for keycaps, you've probably come across terms like MOA, XDA, and OEM. These refer to the profile of the keycap — its shape, height, and curvature. The profile you choose affects how your keyboard looks, feels, and sounds. Here's a breakdown of the three most popular options.
OEM Profile
OEM (Original Equipment Manufacturer) is the most widely used keycap profile in the world. It's what you'll find on most pre-built keyboards right out of the box.
- Height: Medium-tall
- Shape: Sculpted — each row has a slightly different angle
- Top surface: Slightly cylindrical (curved left to right)
- Feel: Familiar and comfortable for most typists
Best for: Beginners, everyday typists, and anyone upgrading from a stock keyboard who wants a familiar feel.
XDA Profile
XDA is a flat, uniform profile — meaning every row is the same height and angle. It has a modern, clean look that's become popular in the custom keyboard community.
- Height: Medium-low
- Shape: Uniform — all rows are identical
- Top surface: Slightly spherical (curved in all directions)
- Feel: Smooth and consistent across the board
Best for: Minimalist setups, ortholinear keyboards, and typists who prefer a flatter typing angle.

MOA Profile
MOA is a newer uniform profile that sits between XDA and taller options like SA. It features a more pronounced spherical top, giving it a distinctive look and a satisfying typing feel.
- Height: Medium
- Shape: Uniform — all rows are identical
- Top surface: Deeply spherical (more curved than XDA)
- Feel: Smooth with a slightly scooped fingertip landing
Best for: Enthusiasts who want a uniform profile with more character than XDA, and a premium aesthetic.

There's no wrong answer — it comes down to personal preference. If you're new to mechanical keyboards, OEM is a safe, comfortable starting point. If you love a clean, flat look, go with XDA. And if you want something with a bit more personality and a premium feel, MOA is worth exploring.
