Uppercase Greek letter sigma drawn as a summation sign with stepped arm ends
About the Sigma black filled 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 solid black filled version of the sigma icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
