# Stroke width

All icons are designed with SVG elements using strokes.
These have a default stroke width of `2px`.

The `strokeWidth` can be adjusted to create a different look of the icons.

## Adjusting stroke width with `strokeWidth` prop

::: sandpack {template=react showTabs=false editorHeight=300 editorWidthPercentage=60 dependencies="lucide-react"}

```jsx App.js [active]
import { FolderLock } from "lucide-react";

function App() {
  return (
    <div className="app">
      <FolderLock strokeWidth={1} />
    </div>
  );
}

export default App;
```

## Absolute stroke width

When adjusting the `size` prop the size of the stroke width will be relative to the size of the icon, this is the default SVG behavior. The `absoluteStrokeWidth` prop is introduced to adjust this behavior to make the stroke width constant no matter the size of the icon.

This means that when `absoluteStrokeWidth` is enabled and the `size` of the icons is set to `48px` the `strokeWidth` will still be `2px` on the screen.

Note `2px` is the default stroke width for a Lucide icon, this can be adjusted to all sizes.

### Adjusting stroke width with `absoluteStrokeWidth` prop

Setting `absoluteStrokeWidth` to `true` will make the stroke width absolute.

```jsx App.js [active]
import { RollerCoaster } from "lucide-react";

function App() {
  return (
    <div className="app">
      <RollerCoaster
        size={96}
        absoluteStrokeWidth={true}
      />
    </div>
  );
}

export default App;
