Keycaps are the parts of a keyboard that cover the switches and provide the surface for typing. They can be made from a variety of materials, each with its own set of advantages and disadvantages.


The most common materials for keycaps are ABS (acrylonitrile-butadiene-styrene) and PBT (polybutylene terephthalate) plastics. ABS is a lightweight and relatively inexpensive material that provides a smooth and shiny surface. However, it is not as durable as PBT and can become shiny and slippery over time. PBT, on the other hand, is a denser and more durable plastic that has a slightly textured, matte surface. It is resistant to wear and tear and maintains its appearance over time, but it is generally more expensive than ABS.

In addition to plastic, keycaps can also be made from metal, such as aluminum or zinc alloy. Metal keycaps provide a unique feel and sound when typing, but they are heavy and expensive.


The profile of a keycap refers to its shape and height. There are several profiles available, including:

OEM: The most common profile, found on most standard keyboards. OEM keycaps have a curved surface and a medium height.
Cherry: Similar to OEM, but with a slightly shorter height.
SA: A tall and sculpted profile that provides a vintage look. SA keycaps have a spherical surface and a high profile.
DSA: A uniform profile with a flat top surface and a uniform height. DSA keycaps are popular among gamers.
When choosing a keycap profile, consider factors such as comfort, typing speed, and aesthetic preferences.

Keycap Set

Keycap sets can vary in the number of keys included, depending on the keyboard's layout. A full keycap set typically includes 104 keys, which covers a standard ANSI layout keyboard. Partial sets are available for smaller keyboards, such as 60% or 65% layouts, which do not have a numeric keypad or function row.

When selecting a keycap set, it is important to ensure that the keycap set is compatible with your keyboard's layout. Many custom mechanical keyboards have non-standard layouts, which may require specific keycaps.



Finally, keycaps come in various designs and colors, allowing for customization and personalization of your keyboard. Designs can range from simple and solid colors to elaborate and intricate patterns. Some keycaps are backlit, allowing the keyboard's LED lighting to shine through.
Key cap design
When choosing a design, consider personal preferences and how well it matches the overall aesthetic of the keyboard. For example, a monochromatic color scheme may complement a minimalist keyboard, while colorful and patterned keycaps may be better suited for a gaming keyboard.

In conclusion, selecting keycaps involves considering factors such as material, profile, keycap set, and design. By taking these factors into account, you can choose keycaps that not only enhance the typing experience but also add a personal touch to your keyboard.
