About the Pi black filled icon
The Greek letter pi is drawn as a long horizontal crossbar over two vertical legs that finish in small hooked curls, giving it a calligraphic serif feel. It represents the mathematical constant, geometry, circles and formulas generally. Use it in math courseware, calculator and spreadsheet tools, engineering documents, science presentations and Pi Day or STEM event graphics.
The crossbar extends slightly past both legs and the mirrored curls balance the letterform, so it reads as typography rather than a plain glyph. It pairs with other math marks in the library such as sigma, infinity and square root. Set it on a generous baseline so the delicate curls do not clip.
This is the solid black filled version of the pi icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
