# 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"
  :theme="sandpackTheme"
  :files="strokeWidth"
  :customSetup='{
    dependencies: {
      "lucide-react": "latest"
    }
  }'
  :options="{
    editorHeight: 300,
    editorWidthPercentage: 60,
  }"
/>

## 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.

  :theme="sandpackTheme"

  :customSetup='{
    dependencies: {
      "lucide-react": "latest"

  }'
  :options="{
    editorHeight: 320,
    editorWidthPercentage: 60,
  }"
