What this style means
Thin icons are light-stroke icons drawn with the thinnest weights available in each library. IconStash classifies icons by style across all 28 indexed libraries, so you can hold the weight constant and compare how different design teams solve the same icon.
When to use them. Thin icons look refined next to large type in spacious layouts. They lose contrast against busy backgrounds and beside small text, so keep them out of dense tables and toolbars.
Every icon below links to a page with the full SVG source, a live preview you can recolour and resize, PNG export at six sizes, and a ready-to-paste React snippet.
