What Is a Keycap Profile?
When people talk about keycap profiles, they're referring to the shape, height, and angle of the keycap tops as seen from the side. A profile determines how the keyboard feels under your fingers, how your wrists sit while typing, and even how the board sounds. Choosing the right profile is just as important as choosing the right switch.
Most profiles are sculpted (meaning each row has a different height/angle) or uniform (every key is the same shape, regardless of row). Here's a rundown of the most common profiles you'll encounter.
OEM Profile
OEM is the most common profile found on pre-built keyboards. It's a sculpted, medium-height profile — taller than Cherry but shorter than SA. Most people typing on a standard keyboard right now are using OEM keycaps. It's a safe, comfortable choice for beginners, and compatible sets are widely available at affordable prices.
Cherry Profile
Cherry profile is slightly shorter than OEM and is widely considered the gold standard among enthusiasts. Its sculpted design keeps fingers in a natural position, and the lower height reduces finger travel. Cherry profile keycaps are among the most abundant in the hobby — brands like GMK produce legends-rich sets almost exclusively in Cherry profile. If you're unsure what to start with, Cherry profile is a reliable choice.
SA Profile
SA (Spherical All) is a tall, retro profile with a deeply sculpted, spherical top surface (concave in two axes). It evokes vintage typewriter aesthetics and produces a loud, high-pitched "clack" when typing. SA is beloved by enthusiasts who enjoy the look and sound, but the tall height can cause wrist fatigue for some — a wrist rest is often recommended.
DSA Profile
DSA is a low, uniform profile with a slightly spherical top. Because every row is the same height, DSA sets are versatile — great for non-standard layouts and 40% keyboards where remapping rows is common. The typing feel is flatter and more horizontal than sculpted profiles. Some love the minimalist feel; others miss the row-to-row ergonomic variation.
XDA Profile
XDA is similar to DSA — uniform, flat, and low — but with a wider top surface. This gives a more spacious typing area per key. XDA is popular in budget group buys and is often found on community-designed sets. Good for those who find DSA a bit cramped but still want a uniform layout.
MT3 Profile
Designed by Matt3o and produced by Drop, MT3 is a sculpted, high-profile set with deep concave scoops — arguably the most ergonomic profile available. The deep dish guides each fingertip naturally into position. MT3 has a devoted following and is particularly praised for its typing feel on 65% and TKL layouts.
KAT / KAM Profile
KAT (Keyreative All Top) is a sculpted profile sitting between Cherry and SA in height. It has a smooth, uniform-depth scoop. KAM is the uniform version of KAT. Both are produced by Keyreative and have grown in popularity thanks to community group buys.

Which Profile Should You Choose?
If you're new to the hobby, start with Cherry or OEM — they're familiar, widely available, and comfortable. If you want to explore sound and aesthetics, try SA. For non-standard layouts, DSA or XDA gives you flexibility. There's no wrong answer, and most enthusiasts end up trying several profiles before settling on favorites.
