Uppercase Greek letter sigma drawn as a summation sign with stepped arm ends
About the Sigma black outline icon
The uppercase Greek letter sigma is drawn as an angular summation sign: two diagonals meeting at a sharp point on the left, closed by top and bottom arms that step inward at their ends. It stands for sums, totals and statistical notation, useful in spreadsheet toolbars, calculator and math learning apps, engineering documentation, data analysis dashboards and physics course materials.
The letterform is wide with a deep central notch, and the small stepped returns on the arms give it a classic type feel instead of a plain zigzag. It pairs with pi, delta, infinity and percent icons in the set. Use it as a toolbar button for an autosum or total action.
This is the black outline version of the sigma icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
