Block

The block icon represents a basic building unit or a simple geometric shape. It is commonly used in construction, architecture, or design.

In software and platforms, the block icon is often used in computer-aided design (CAD) or building information modeling (BIM) tools.

From a UX perspective, the block icon communicates the idea of building or constructing something. It helps users understand that they can create or modify a structure.

Block is one of 514 icons in Röntgen, made by Sergey Vartanov and released under CC BY 4.0. It is drawn on a 16 × 16 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 BlockIcon to components/icons/roentgen-block.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 BlockIcon 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 Block icon, or any of 514 Röntgen 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 16 × 16 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="Block", so screen readers say what it does.

Yes. BlockIcon passes every SVG prop to the svg element, so <BlockIcon 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 credit: CC BY 4.0 asks you to credit the author (Sergey Vartanov) where you use the icons. The full terms are in the license, linked on this page.

Yes. CC BY 4.0 asks you to credit the author where you use the icons, for example "Icons by Sergey Vartanov, CC BY 4.0" on an about or credits page.

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