You can upload your own font directly from the font picker in the Playground.
Step 1: open the font picker
Step 2: click the upload button
The fonts you upload will be added to the “My Fonts” section so you can use them for any other keycaps set.
💡 Formats supported: TTF, OTF, WOFF, WOFF2
No, variable fonts are not supported at the moment. You’ll need to use static font files instead.
Yeah, we’ve seen this too — it’s a limitation of the rendering library we use. Some fonts don’t kern properly inside the Playground. Unfortunately, there’s no fix for this just yet.
Here are some great places to explore fonts:
💡 Always check the font’s license before using it in a printed product like a keycap set.
If you’re using a free font, you’re usually good — but double-check the license! Some fonts don’t allow commercial use or physical reproduction. If the font has a restrictive license, make sure it allows you to print it on goods like keycaps.
GMK’s original Cherry keycaps use a variant of Helvetica Rounded Bold.
