Pi

The pi icon represents the mathematical constant pi, symbolizing mathematical relationships and geometric proportions. It originates from ancient mathematical discoveries. The icon signifies mathematical concepts and calculations.

In real-world applications, this icon appears in mathematical software, educational resources, and scientific interfaces. For instance, it may be used in geometry calculations, mathematical formulas, or scientific notation.

From a UX perspective, the pi icon communicates a sense of mathematical relevance and precision. It helps users understand that a particular feature or section relates to mathematical concepts or calculations.

Pi is one of 336 icons in Typicons, made by Stephen Hutchings and released under CC BY-SA 4.0. It is drawn on a 24 × 24 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds PiIcon to components/icons/typcn-pi.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed PiIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Pi icon, or any of 336 Typicons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Pi", so screen readers say what it does.

Yes. PiIcon passes every SVG prop to the svg element, so <PiIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes, with conditions: CC BY-SA 4.0 asks you to credit the author (Stephen Hutchings), and icons you change must use the same license. The full terms are in the license, linked on this page.

Yes. CC BY-SA 4.0 asks you to credit Stephen Hutchings, and icons you change must be shared under the same license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.

8 other libraries draw an icon called Pi. The Other libraries section on this page shows each one, so you can compare them and open the one that fits your style.

Its tags are symbol, math, mathematics and ratio. Each tag page lists the icons that carry it from every library, which is the quickest way to find a match for Pi in another set.

Typicons draws many icons in several styles: Outline next to the default. Open the library and pick a style above the grid to see Pi's siblings in it.
