Protractor black filled icon

About the Protractor black filled icon

This design shows a half-circle protractor seen face on. Short degree ticks run around the outer arc, an inner dome outlines the open measuring window, and the flat baseline carries five evenly spaced scale marks along a straight ruler edge. It communicates measurement, angles, geometry and precision, and works well in math learning apps, school supply shops, engineering tool palettes, drawing app toolbars and classroom presentations.

The arc and the baseline share the same stroke weight, and the inner semicircle is offset evenly so the instrument reads as hollow rather than solid. The wide, short proportions make it sit comfortably in a horizontal toolbar row. It pairs with ruler, compass, set square and pencil icons from the same stationery set. Keep tick marks legible by using it at 24px or above.

This is the solid black filled version of the protractor icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
