Square Root black outline icon
Outline icon of a square root radical sign with a long horizontal bar
About the Square Root black outline icon
The icon draws the radical symbol on its own: a short horizontal lead-in, a sharp descending and rising V, then a long overbar extending to the right where a radicand would sit. It stands for square roots, algebra, formulas and scientific calculation. Use it on calculator keypads, math learning apps, equation editor toolbars, exam and tutoring sites, and engineering or statistics documentation.
Strokes thicken through the V and stay thin along the bar, echoing how the glyph is typeset, and the empty bar leaves room to place a number or expression beside the icon. It pairs with plus, minus, percent and pi icons in a math symbol set. Because it is wide and low, give it extra side padding on square buttons.
This is the black outline version of the square root icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
