The Ultimate Guide to Keycaps

Keycaps are the interface between your fingers and the switch of the keyboard. They affect the sound, feel, and aesthetics of your keyboard more than any other component. Changing your keycaps is the easiest way to completely transform your keyboard's personality.

Colorful GMK Keycaps on a Keyboard

01. Comparison: ABS vs PBT

The two most common plastics used. Neither is strictly "better," but they serve different preferences.

ABS Plastic

Acrylonitrile Butadiene Styrene. The industry standard for high-end vibrant sets (like GMK).

  • Feel: Smooth, sometimes slick.
  • Sound: Higher pitched, "clackier".
  • Look: Extremely vibrant colors.
  • Cons: Develops a "shine" (oily look) after heavy use.

PBT Plastic

Polybutylene Terephthalate. Known for durability and resistance to wear.

  • Feel: Textured, sandy, dry.
  • Sound: Deeper, "thockier".
  • Look: Colors are usually more muted (though improving).
  • Pros: Will never shine. Legends stay matte forever.

02. Keycap Profiles (Shape)

Not all keycaps are shaped the same. The "Profile" determines the height and sculpting of the keys.

Cherry Profile

The gold standard. Cylindrical top, lower height. Comfortable for typing and gaming. Most custom customs use this.

OEM Profile

Similar shape to Cherry but slightly taller. Standard on most pre-built keyboards (Razer, Corsair, Keychron).

SA Profile

Tall, spherical (rounded) tops, and retro-looking. Produces a very deep "thock" sound but can be tiring to type on without a wrist rest.

XDA / DSA

Flat and uniform height. Every key is the same shape. Looks clean and modern, but lacks ergonomic sculpting.

03. Manufacturing Methods

How the letters (legends) are put on the caps matters for longevity.

04. Where to Buy in Malaysia

Sourcing keycaps locally saves you massive shipping fees and import taxes.
