FatBoySmiles

Fat Boy Smiles font by Jakob Fischer is a free cartoon display typeface that looks like it was doodled with a chunky black marker on a scrap of notebook paper. Each letter wobbles a little, with loose outlines and bouncy proportions, while the happy faces tucked inside bring an instant dose of mischief and warmth. It feels hand-drawn, lighthearted, and just a bit chaotic—in the best way.

Using Fat Boy Smiles, headlines feel like they’re shouting with joy rather than volume. This free font shines on kids’ posters, party invitations, playful logos, classroom materials, comic-style graphics, and social media posts that need a friendly wink. Keep it big for maximum impact, and pair it with a clean sans serif for body text so the quirky outlines stay easy to read.
