Pi black outline icon
Bold Greek letter pi with a curled left leg and rounded stroke ends
About the Pi black outline icon
A heavy Greek letter pi fills the frame: a long horizontal bar across the top with rounded caps, a left leg that curls inward at the foot and a straight right leg. It stands for the mathematical constant, circles and circumference, geometry and general science. Use it in calculator apps, math learning platforms, formula editors, engineering tools and classroom slides or worksheets.
The strokes are uniformly thick with softened terminals, and the curled left foot gives the glyph a calligraphic lean that separates it from a plain typeface pi. It works alongside sigma, infinity, square root and percent marks from the same math set. Because the form is dense, it stays legible down to 16 px in toolbars.
This is the black outline version of the pi icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
