Font Size

​

Basic usage

​

Setting the font size

Control the font size of an element using the text-{size} utilities.

<p class="text-sm ...">The quick brown fox ...</p>
<p class="text-base ...">The quick brown fox ...</p>
<p class="text-lg ...">The quick brown fox ...</p>
<p class="text-xl ...">The quick brown fox ...</p>
<p class="text-2xl ...">The quick brown fox ...</p>

​

Applying conditionally

​

Hover, focus, and other states

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:text-base to only apply the text-base utility on hover.

<p class="text-sm hover:text-base">
  <!-- ... -->
</p>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

​

Breakpoints and media queries

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:text-base to apply the text-base utility at only medium screen sizes and above.

<p class="text-sm md:text-base">
  <!-- ... -->
</p>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

​

Using custom values

​

Customizing your theme

You can configure your own custom set of font size utilities using the theme.fontSize section of your tailwind.config.js file.

module.exports = {
  theme: {
    fontSize: {
      sm: '0.8rem',
      base: '1rem',
      xl: '1.25rem',
      2xl: '1.563rem',
      3xl: '1.953rem',
      4xl: '2.441rem',
      5xl: '3.052rem',
    }
  }
}

Learn more about customizing the default theme in the theme customization documentation.

​

Providing a default line-height

Tailwind’s default theme configures a sensible default line-height for each text-{size} utility. You can configure your own default line heights when using custom font sizes by defining each size using a tuple of the form [fontSize, lineHeight] in your tailwind.config.js file.

module.exports = {
  theme: {
    fontSize: {
      sm: ['14px', '20px'],
      base: ['16px', '24px'],
      lg: ['20px', '28px'],
      xl: ['24px', '32px'],
    }
  }
}

You can also specify a default line height using the object syntax, which allows you to also provide default letter-spacing and font-weight values. You can do this using a tuple of the form [fontSize, { lineHeight?, letterSpacing?, fontWeight? }].

module.exports = {
  theme: {
    fontSize: {
      '2xl': ['1.5rem', {
        lineHeight: '2rem',
        letterSpacing: '-0.01em',
        fontWeight: '500',
      }],
      '3xl': ['1.875rem', {
        lineHeight: '2.25rem',
        letterSpacing: '-0.02em',
        fontWeight: '700',
      }],
    }
  }
}

​

Arbitrary values

If you need to use a one-off font-size value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<p class="text-[14px]">
  <!-- ... -->
</p>

Learn more about arbitrary value support in the arbitrary values documentation.
