An Overview On Keycaps

If you’re a gamer with a mechanical keyboard, you know one of the best ways to upgrade your keyboard is with a new set of keys. You can completely change the look and feel of your keyboard to enhance your gaming experience.

Most keyboards come with mass-produced keycaps that are dull and plain. If you’re spending hours each day at your keyboard, it’s much more exciting to have something lively and fun to look at. Not only do keycaps come in stunning colors with cool effects, you can also get them made from more durable materials so they won’t fade or break with heavy usage. With so many different types of keycaps available though, how do you choose the set that’s right for you?

One of the most important elements to consider when you’re buying new keycaps is the material they are made out of. The two most common options you will find are ABS (Acrylonitrile Butadiene Styrene) and PBT (Polybutylene Terephthalate). ABS is the more affordable choice, and it’s typically also quieter when typing. The material has a shiny look that can wear over time. PBT is more costly and creates a satisfying sound when used. The look is more matte and textured than ABS. This material is also highly durable.

The Keycap Buying Guide

  • Many people have a specific preference when it comes to the profile, or overall shape, of the keycap. Common varieties include flat and rounded keycaps. Some styles include different rows of keys having a particular height to create a concave or sloped shape on your keyboard.
  • Uniform keycaps have a flat top, while sculpted keycaps have a slightly angled surface. The benefit to having a sculpted keycap is that your fingers don’t have to stretch as far when typing. Most people prefer sculpted keycaps, but some like the look of the uniform variety. Many gamers prefer a cherry profile for their keycaps. This is a sculpted variety that is efficient and comfortable to use.
  • Before purchasing your keycap set, make sure that it is compatible with the size and layout of your keyboard. Some keycap sets are for tenkeyless layouts, so it’s important to check for a match before you get a new set. Keep in mind some keyboards have a differently sized Enter key on the right-hand side, so it’s best to make sure your keycaps will fit it properly.
