Sizing

By default, the size of all icons is 24px by 24px. The size is adjustable using the size prop and CSS.

Adjusting the icon size using the size prop

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

tsx
import Landmark from 'lucide-solid/icons/landmark';

function App() {
  return (
    <div class="app">
      <Landmark size={64} />
    </div>
  );
}

export default App;

Adjusting the icon size via CSS

The CSS properties width and height can be used to adjust the icon size.

::: sandpack {template=vite-solid editorHeight=300 dependencies="lucide-solid"}

css
.my-beer-icon {
  /* Change this! */
  width: 64px;
  height: 64px;
}
tsx
import Beer from 'lucide-solid/icons/beer';

import "./icon.css";

function App() {
  return (
    <div class="app">
      <Beer class="my-beer-icon" />
    </div>
  );
}

export default App;

Dynamically change the icon size based on the font size

It is possible to resize icons based on font size. This can be achieved using the em unit. See this MDN article for more information on the em unit.

::: sandpack {template=vite-solid editorHeight=300 dependencies="lucide-solid"}

css
.my-icon {
  /* Icon size will relative to font-size of .text-wrapper */
  width: 1em;
  height: 1em;
}

.text-wrapper {
  /* Change this! */
  font-size: 96px;

  /* layout stuff */
  display: flex;
  gap: 0.25em;
  align-items: center;
}
tsx
import Star from 'lucide-solid/icons/star';
import "./icon.css";

function App() {
  return (
    <div class="text-wrapper">
      <Star class="my-icon" />
      <div>Yes</div>
    </div>
  );
}

export default App;

Resizing with Tailwind

size-* utilities can be used to adjust the size of the icon. See the Tailwind documentation for more information on the size-* utilities.

::: sandpack {template=vite-solid editorHeight=300 editorWidthPercentage=60 dependencies="lucide-solid" externalResources="https://cdn.tailwindcss.com"}

tsx
import PartyPopper from 'lucide-solid/icons/party-popper';

function App() {
  return (
    <div>
      <PartyPopper class="size-24" />
    </div>
  );
}

export default App;
