# Sizing

Sizing units create visual hierarchy.

## Using sizing tokens

<div className="tip-wrapper">
  <span className="tip">Tip</span>Sizing are defined as CSS Custom properties,
  to use them, use: <code>var(--sizing-base)</code> as the CSS property value.
</div>

```
font-size: var(--sizing-base);
```

### How to apply sizing units

Use font size to indicate the hierarchy of content within an interface.

Golden rule is to stick to 3-4 font sizes within a single view.
