Quattro Light by David Espinosa is a free retro display font with extremely fine, even strokes and unusually tall, rounded forms. The clean squared curves recall streamlined machine-age lettering.
Technology and mid-century futurism make it a natural fit for electronics branding and exhibition posters. It also suits album artwork and fashion packaging that favor spare geometric lettering. In editorial design, its distinctive silhouettes can shape section openers and feature titles.
