Line Height

Relative line-heights

Use the leading-none, leading-tight, leading-snug, leading-normal, leading-relaxed, and leading-loose utilities to give an element a relative line-height based on its current font-size.

Fixed line-heights

Use the leading-{size} utilities to give an element a fixed line-height, irrespective of the current font-size. These are useful when you need very precise control over an element's final size.

Responsive

To control the line height of an element at a specific breakpoint, add a {screen}: prefix to any existing line height utility. For example, use md:leading-loose to apply the leading-loose utility at only medium screen sizes and above.

<p class="leading-none md:leading-loose ...">Lorem ipsum dolor sit amet ...</p>

For more information about Tailwind's responsive design features, check out the Responsive Design documentation.

It's important to note that by default, Tailwind's font-size utilities each set their own default line-height. This means that any time you use a responsive font-size utility like sm:text-xl, any explicit line-height you have set for a smaller breakpoint will be overridden.

<!-- The `leading-loose` class will be overridden at the `md` breakpoint -->
<p class="text-lg leading-loose md:text-xl">
  Lorem ipsum dolor sit amet ...
</p>

If you want to override the default line-height after setting a breakpoint-specific font-size, make sure to set a breakpoint-specific line-height as well:

<!-- The `leading-loose` class will be overridden at the `md` breakpoint -->
<p class="text-lg leading-loose md:text-xl md:leading-loose">
  Lorem ipsum dolor sit amet ...
</p>

Using the same line-height across different font sizes is generally not going to give you good typographic results. Line-height should typically get smaller as font-size increases, so the default behavior here usually saves you a ton of work. If you find yourself fighting it, you can always customize your font-size scale to not include default line-heights.

Customizing

By default, Tailwind provides six relative and eight fixed line-height utilities. You change, add, or remove these by customizing the lineHeight section of your Tailwind theme config.

  // tailwind.config.js
  module.exports = {
    theme: {
      extend: {
        lineHeight: {
+         'extra-loose': '2.5',
+         '12': '3rem',
        }
      }
    }
  }

Variants

By default, only responsive variants are generated for line height utilities.

You can control which variants are generated for the line height utilities by modifying the lineHeight property in the variants section of your tailwind.config.js file.

For example, this config will also generate hover and focus variants:

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       lineHeight: ['hover', 'focus'],
      }
    }
  }

Disabling

If you don't plan to use the line height utilities in your project, you can disable them entirely by setting the lineHeight property to false in the corePlugins section of your config file:

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     lineHeight: false,
    }
  }
