Feather

Feather is an open-source set of 287 icons, each drawn on a 24x24 grid with consistent strokes for simplicity and readability. The site lets you adjust size, stroke width and colour before copying or downloading, and the icons are available as SVG and through packages for common frameworks. Try the stroke-width control first to see how the set holds up at your sizes, and note that the larger Lucide library began as a fork of Feather.
