What these 12 fun fonts share, and where they differ
By structure the set is uniform: each of the 12 is a display font, the same family of shapes as the Display Fonts page. 2 of the 12 are in the free collection (Bubble Cloud Lobed and Display Retro Bubble), so a free account can download them as TTF; the other 10 download with Pro, Studio or a Font Pass. 1 comes in more than one weight (Bubble Candy Inflate), the other 11 in a single Regular style. Besides fun, the library most often files these fonts as bubble (10), birthday (6), cute (6) and kids (5).
All 12 fonts stand upright. Widths vary a lot: an average lowercase letter runs from 62.7% of the cap height in Dreamslug Grotesk to 97% in Display Retro Bubble. For the fun fonts as a group the median is 82.3%, level with the 81% median of the whole library, so line lengths match an average library font. Measured against their capitals, the fun fonts here put the top of the lowercase between 67.5% and 78.6% of the cap height, 75.3% at the median; the library median is 71.8%. By ink coverage, Bubble Gel Wobble is the lightest of these fun fonts at 46.7% of each letter's box and Display Retro Bubble the darkest at 61.1%; the median here, 54.9%, is 60% darker than the library's 34.3%. Of the 11 whose stroke contrast could be read from the o, 8 keep close to one stroke weight in every direction and 1 is heavier across than down, a reversed contrast. Outlines, shadows and 3D sides play no part in these fun fonts; each one is plain filled letters.
Every measured font here covers the Latin alphabet only; character sets run from 95 to 345. 8 of the 12 include accented Latin letters beyond A to Z; the other 4 stop at the basic alphabet, so check names with accents in the preview first. 1 of the 12 adjusts spacing with kerning pairs (a median of 10,920); Dreamslug Grotesk has the most, 10,920. In the OpenType tables, none has OpenType ligatures or alternates; as for numbers, none has tabular figures, so columns of numbers will not align exactly.
Measured from the font files of 12 of the 12 fonts on this page: widths and heights are shares of the cap height. Library comparisons use the 354 library fonts measured on October 6, 2026.
Which fun font to start with
For short, wide headlines
Display Retro Bubble runs 18% wider than the page median (97% of the cap height per lowercase letter), which fills a banner with one or two words.
For small sizes
Bubble Candy Inflate has an x-height of 77.7% of the cap height, among the tallest here, so its lowercase stays legible on stickers, labels and phone screens.
For a lighter touch
Bubble Gel Wobble is the lightest here at 46.7% ink coverage, airy enough for quotes, invitations and longer lines.
For other languages
Dreamslug Grotesk has the largest character set here, 345, including 193 accented and special Latin letters.

Questions about fun fonts
- Can I use these fun fonts commercially?
- Yes, with a Pro or Studio plan: downloads made on either come with a commercial license for logos, products, merchandise and client work, and it continues after the plan ends. 2 of the 12 are also in the free collection, which a free account can download as TTF for personal projects (up to 3 different free fonts a month). A Font Pass downloads 5 library fonts of your choice for personal use.
- Which file formats do these fun fonts come in?
- All four formats, TTF, OTF, WOFF and WOFF2, come with each of the 12 on Pro and Studio, and the free collection downloads as TTF. 1 comes with more than one weight and the rest with one style, and their files hold 95 to 351 glyphs. TTF and OTF install on Windows and macOS; WOFF2 is the one to load on a website.
- Do these fun fonts support languages other than English?
- All of them are Latin fonts. 8 of the 12 measured have accented Latin letters for languages such as French, Spanish and German; the rest cover A to Z only. If a language is missing, Customize makes a copy of the font in your account, and Studio adds the letters it needs.
- Can I make my own fun font?
- Yes. Describe it in the generator, or upload a picture of lettering you like, and AI draws a complete installable font you can then edit letter by letter in Studio. The 12 fonts here make a useful brief: most of them stand upright and have a taller x-height than the library median (the median x-height is 75.3% of the cap height), so a prompt such as "a fun font, upright, tall x-height" starts close to this page.
