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"}

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.

::: sandpack {template=react showTabs=false editorHeight=320 editorWidthPercentage=60 dependencies="lucide-react"}

import { RollerCoaster } from "lucide-react";

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

export default App;
