A sans serif font is a typeface whose letters don't have the small decorative strokes, called serifs, at the ends of their lines. This gives the letterforms a cleaner, more geometric look compared to serif fonts.
‍
Common examples include Helvetica, Arial, and Roboto. Sans serif fonts are widely used in digital interfaces because their simple shapes stay legible even at small sizes and on low-resolution screens.

Why does Sans Serif Font matter?

Sans serif fonts are a go-to choice for UI text, body copy, and headings because their clean, uniform strokes reduce visual clutter and render crisply across devices and screen sizes.

Many popular design systems, like Google's Material Design and Apple's Human Interface Guidelines, default to sans serif typefaces for exactly this reason. They pair well with modern, minimal interfaces and improve readability in short bursts of text like buttons, labels, and navigation.
