About the Sigma Symbol black outline icon
The uppercase Greek letter sigma drawn as a solid glyph with crisp angled arms meeting at a sharp central point. In mathematics it is the summation operator, so it stands for totals, aggregation and statistical calculation as much as for the Greek alphabet itself. Use it in spreadsheet and calculator toolbars, formula editors, statistics dashboards, math and physics course pages, and science or fraternity themed layouts.
Proportions follow a classic serif-free letterform: heavy diagonals, thinner horizontal bars, and slight flare at the terminals that keeps the top and bottom strokes from looking cut off. It pairs with pi, infinity and percent glyph icons. As a text-like mark it carries very small sizes well, but keep clear space around the sharp apex.
This is the black outline version of the sigma symbol icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
