SF Diego Sans Outline

SF Diego Sans Outline by ShyFoundry is a free outlined comic display font with a breezy mid-century cartoon feel. The letters are drawn as clean hollow shapes with soft corners and easy, hand-done curves, giving the caps a playful bounce without turning messy or loud.

That makes it a natural fit for poster headlines, kids' book covers, retro packaging, cheerful title cards, and store signage where a little air inside the letters helps the words feel open. As a free font, it also works well for logos, monograms, and short cover lines, especially when you want something friendly and graphic rather than heavy.
