FAQ
Answered from square-radical's own facts: its shelf, the weights it was drawn in, its siblings and its dates.
- What is the square-radical icon for?
- The radical sign, for square roots, formulas and maths input. It is filed under Math in Keyline Icons, drawn on the same 24×24 grid as the rest of the set. People look for it as square root, root, sqrt, math, formula, calculate and operator, and the browser's search matches all of those.
- What styles does the square-radical icon come in?
- All four: stroke, two-tone, duotone and fill. They are drawn from the same geometry, so swapping style never moves anything.
- How is square-radical different from radical?
- square-radical is the same drawing inside a square. The bare glyph is radical, and it is also boxed as circle-radical.
- What other icons go with square-radical?
- asterisk, circle-asterisk, circle-divide, circle-equal, divide and equal, and 11 more, all shown below. They are the Math shelf: nothing else in the set is named after radical.
- How do I import square-radical in React?
- <SquareRadical /> is the component, and the weight decides the module: stroke from "@keyline-icons/react", two-tone from "@keyline-icons/react/two-tone", duotone from "@keyline-icons/react/duotone" and fill from "@keyline-icons/react/fill". It takes the usual SVG props plus a size, so <SquareRadical size={16} /> and className="size-4" both work, and there is no provider or theme to set up.
- Where is the square-radical SVG?
- icons/stroke/square-radical.svg, icons/two-tone/square-radical.svg, icons/duotone/square-radical.svg and icons/fill/square-radical.svg in the repository, normalised: no wrapper, no ids and no classes to strip out. The tabs above hand you the same drawing as SVG or JSX without the download, and neither needs an install.
- When was square-radical added to the set?
- Added 22 Sept 2026. It ships in v1.1.0, so an install at that version or later has it.
Questions about the set rather than about this drawing are answered where they belong. The home page covers what the set is, how the three styles differ, why some icons come boxed and where the Figma file is; installing the set in a shadcn/ui project covers the React package, the CLI and using an icon without React. The MIT licence is stated in the footer of every page.
