Both our Web Fonts + CSS and SVG + JS frameworks include some basic controls for sizing icons in the context of your page's UI.

Relative Sizing

Icons inherit the font-size of their parent container which allow them to match any text you might use with them. With the following classes, we can increase or decrease the size of icons relative to that inherited font-size.

  <i class="fas fa-camera fa-xs"></i>
  <i class="fas fa-camera fa-sm"></i>
  <i class="fas fa-camera fa-lg"></i>
  <i class="fas fa-camera fa-2x"></i>
  <i class="fas fa-camera fa-3x"></i>
  <i class="fas fa-camera fa-5x"></i>
  <i class="fas fa-camera fa-7x"></i>
  <i class="fas fa-camera fa-10x"></i>

Here are a few more examples where you can see the relative scale.

  <div style="font-size: 0.5rem;">
    <i class="fas fa-camera fa-xs"></i>
    <i class="fas fa-camera fa-sm"></i>
    <i class="fas fa-camera fa-lg"></i>
    <i class="fas fa-camera fa-2x"></i>
    <i class="fas fa-camera fa-3x"></i>
    <i class="fas fa-camera fa-5x"></i>
    <i class="fas fa-camera fa-7x"></i>
    <i class="fas fa-camera fa-10x"></i>
  </div>

  <div style="font-size: 24px;">
    <i class="fas fa-camera fa-xs"></i>
    <i class="fas fa-camera fa-sm"></i>
    <i class="fas fa-camera fa-lg"></i>
    <i class="fas fa-camera fa-2x"></i>
    <i class="fas fa-camera fa-3x"></i>
    <i class="fas fa-camera fa-5x"></i>
    <i class="fas fa-camera fa-7x"></i>
    <i class="fas fa-camera fa-10x"></i>
  </div>

Did You Know?

You can also directly style an icon's size by setting a font-size in your project's CSS that targets an icon or directly in the style attribute of the HTML element referencing an icon.
