What Are Custom Keycaps?

Upgrade the look and feel of your typing experience with the perfect custom keycap set

Perhaps the greatest joy of the mechanical keyboard hobby is the endless depths of customization it allows. Utilitarians will likely tell you the most important part is those feel-and-sound-defining switches, and sure, that may be true — but what’s the first thing you notice every time you admire a fully assembled board? If key switches are the heart of a mechanical keyboard, then custom keycaps are its bright and beaming face.

This article will introduce or reacquaint you to the joys of the many different types of mechanical keys that you can use to make your own perfect typing experience, including some of the best places to find custom keycaps, an assortment of the most popular models on the market, and even how to install a custom keycap set yourself (good news, it’s surprisingly easy). But first, let’s define what we’re about to talk about.

What are custom keycaps?

Keycaps are the part of a computer keyboard that your fingers rest on and press down during the normal operation of the board. In the case of mechanical keyboards, pushing a keycap down compresses the spring of the mechanical key switch underneath, and then the same spring propels the keycap back up once you lift your finger. Custom keycaps are any set of caps that are sold on their own, either to be swapped out for use in a keyboard with pre-installed caps or for a fully custom board. They are created by and for mechanical keyboard enthusiasts for a number of reasons, like the aesthetic appeal of dropping in unique keycap color schemes as well as the ergonomic benefits of different keycap profiles.

The majority of custom keycaps on the market, whether they’re sold in a pack meant to outfit an entire keyboard or as artisan custom single keycaps, are compatible with the cross-stem switch design popularized by the Cherry corporation and adopted by a range of competitors. Most mechanical keyboards on the market today — whether mass market or boutique-built — will fit the bill, but if your board of choice uses a different type of switch, your customization options will be more limited.

Where can I find custom keycaps?

The community spirit of the mechanixcal keyboard hobby has kept it vibrant and growing for decades, but it also means there’s no one central place to find and buy different types of custom keycap sets. As long as you don’t mind spending a little extra time to take in all the sights, that distributed nature can be a strength rather than a weakness. Here are three different ways to find your next set of favorite custom keycaps.


The most surefire way to immerse yourself in a constant stream of beautiful new mechanical keyboards, whether you’re looking for just the right retro look or some beautiful new custom backlit keycaps for your RGB build, is to seek out mechanical keyboard communities online.

  • Reddit’s MechanicalKeyboards subreddit has quickly become a hub for the hobby.
  • Geekhack presents a more classic and dedicated forum experience, as well as a chance to get in early on promising new custom keycap sets.
  • High-profile YouTubers such as tinymakesthings have their own dedicated fandoms within the community, introducing their fans to all manner of beautiful new custom keycaps and boards.

You can find even more like-minded lovers of custom keycaps with our guide to The Top 5 Mechanical Keyboard Forums, YouTube Channels, and Subreddits.


A handful of online retailers and marketplaces have emerged as reliable places to find exciting new types of mechanical keys. Here are some destinations to get you started.

  • Drop’s range of custom keycaps isn’t the most affordable, but each set is classy across the board. Drop has a particularly good selection of the tall and concave MT3 profile.
  • Kinetic Labs exclusively sells mechanical keyboard parts (and related accessories, like desk mats) and that focus shows in its eye-catching keycap color schemes.
  • TaroDepato may be the best keycap seller on Etsy, offering a range of original pop-culture-inspired custom keycap sets for surprisingly affordable prices.

Make your own

This option is not for the impatient, and it is not the kind of DIY that’s likely to save you money in the long run. However, you can create your own ultimate custom keycaps by making or modifying them yourself. Check out this guide from prolific YouTube keyboard artisan tinymakesthings on how to make your own designs using standard PBT keycaps and clay.

While uniquely styled artisan keycaps are a joy to behold and press, you probably wouldn’t want a whole keyboard full of them. Here’s a guide from Linus Tech Tips on how to print and dye your own key legends for a somewhat more practical full-custom keycap experience.

Does that seem like a lot? Don’t worry, if you don’t want to make your own custom keycaps, a world of designs are just a few clicks away.

What are some of the most popular custom keycaps?

There are so many options out there, and a big part of the appeal of searching for the perfect custom keycap set is getting a board that looks like nothing else you’ve ever seen. That said, here are some beloved sets to get you started in your search.

  • The Drop + Matt30 Susuwatari Custom Keycap Set is inspired by the Soot Sprites of the beloved Studio Ghibli films. Its range of soft grays bodies set off subtly colorful key legends, and its rounded MT3 profile helps complete the friendly look.
  • Kinetic Labs’ Octopus PBT Keycaps showcase a beautiful range of purples, plums, and pinks, creating one of the most appealing yet approachable keycap color schemes out there at an affordable price.
  • The Tiles Keycap Set from TaroDepato gives you your choice of Cherry or XDA profile keys. Either one will lend your keyboard an idiosyncratic yet dignified aesthetic, like the ballroom floor of a reclusive count’s castle.

How do I install custom keycaps?

The best way to install custom keycaps is fairly straightforward, but it does require the right tool and some patience (especially if you’re swapping out the 100-plus keys of a full-sized board). Please note that these instructions apply only to keyboards with Cherry-MX-style switches — as we noted above, that covers the majority of mechanical keyboards on the market today, but not all of them.

With that said, here’s a step-by-step guide on how to install custom keycaps:

  1. Unplug your board and place it on a clean, flat surface with a good amount of room to work. If your board doesn’t have a pre-existing set of keycaps installed, you can skip to step 5.
  2. Pick up your keycap puller and press the wire loops down onto the left and right sides of an externally located keycap. The loops should separate and then snap back together once they clear the widest part of the cap.
  3. Pull the keycap puller upward, starting with light pressure perpendicular to the surface of the board. Do not pull to one side or you may damage the switch’s key stem. The keycap should slide upward and eventually pop off.
  4. Repeat this process for every key on the board, taking special care for larger keys which may require you to unhook stabilizers before the cap will fully disengage.

    Note: This is also a great opportunity to clean out any dirt which may have become trapped under the keycaps over time. Start with a vacuum cleaner’s hose attachment, then use a damp cloth.

  5. Note the cross-shaped hole on the underside of your new custom keycaps. This will slot directly onto the cross-shaped stem atop each key switch.
  6. Press each keycap into its appropriate position on the board by seating the cap atop the stem and gently pressing straight downward. Do not fully seat each keycap yet.
  7. Once you have confirmed that each keycap is in its desired location, firmly press each one down so it is fully seated on its switch stem.

Then sit back and enjoy your beautifully refreshed board. But beware! Now that you’ve become privy to the wide world of custom keycaps, it may not be long until you feel compelled to swap in another new set. Then another. Then another.

Enjoy a typing experience like no other

We mentioned before that certain types of mechanical keyboards don’t use typical custom keycaps. You may be wondering why that is, and one great product to illustrate the difference is the HHKB Professional HYBRID Type-S. Its Topre key switches are beloved among enthusiasts for both their precision and satisfying “thwock” sound, and their unique actuation model means they require similarly unique keycaps. Beyond its keycaps and switches, the HHKB Pro line offers a subtly updated and future-proof take on a novel keyboard layout that’s been earning converts among coders, hackers, gamers, and more since the late ‘90s.
