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

---
import Landmark from '@lucide/astro/icons/landmark';
---

<Landmark size={64} />

Adjusting the icon size via CSS

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

icon.css

.my-beer-icon {
  width: 64px;
  height: 64px;
}

page.astro

---
import Beer from '@lucide/astro/icons/beer';
import './icon.css'
---

<Beer class="my-beer-icon" />

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.

icon.css

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

.text-wrapper {
  font-size: 96px;

  /* layout stuff */
  display: flex;
  gap: 0.25em;
  align-items: center;
}

page.astro

---
import Star from '@lucide/astro/icons/star';
import './icon.css'
---

<div class="text-wrapper">
  <Star class="my-icon" />
  <div>Yes</div>
</div>
