Sham Extra Bold by Ray Larabie is a free ultra-bold rounded sans from 1996, with a soft, inflated feel that leans playful rather than strict geometric. The letters are broad and compact, with chunky curves, clipped joins, and a low, sturdy rhythm that makes even simple forms feel bouncy.
It fits naturally in posters, kids' branding, snack packaging, arcade-flavored graphics, and punchy magazine cover lines, where the free font can carry a few words with real weight. Use it for short headlines, title cards, logos, or monogram-like initials when you want thick shapes and rounded corners to keep the message friendly instead of severe.
