Font Size

Usage

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

Responsive

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

<p class="text-base md:text-lg ...">The quick brown fox jumps over the lazy dog.</p>

Customizing

Font Sizes

By default, Tailwind provides 10 font-size utilities. You change, add, or remove these by editing the theme.fontSize section of your Tailwind config.

  // tailwind.config.js
  module.exports = {
    theme: {
      fontSize: {
-       'xs': '.75rem',
-       'sm': '.875rem',
+       'tiny': '.875rem',
        'base': '1rem',
        'lg': '1.125rem',
        'xl': '1.25rem',
        '2xl': '1.5rem',
-       '3xl': '1.875rem',
-       '4xl': '2.25rem',
        '5xl': '3rem',
        '6xl': '4rem',
+       '7xl': '5rem',
      }
    }
  }

Providing a default line-height

You can provide a default line-height for each of your font-sizes using a tuple of the form [fontSize, lineHeight] in your tailwind.config.js file.

// tailwind.config.js
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 object syntax:

// tailwind.config.js
module.exports = {
  theme: {
    fontSize: {
      sm: ['14px', {
        lineHeight: '20px',
      }],
    }
  }
}

We already provide default line heights for each .text-{size} class.

Providing a default letter-spacing

If you also want to provide a default letter-spacing value for a font size, you can do so using a tuple of the form [fontSize, { letterSpacing, lineHeight }] in your tailwind.config.js file.

// tailwind.config.js
module.exports = {
  theme: {
    fontSize: {
      '2xl': ['24px', {
        letterSpacing: '-0.01em',
      }],
      // Or with a default line-height as well
      '3xl': ['32px', {
        letterSpacing: '-0.02em',
        lineHeight: '40px',
      }],
    }
  }
}

Variants

By default, only responsive variants are generated for text sizing utilities.

You can control which variants are generated for the text sizing utilities by modifying the fontSize 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: {
        // ...
+       fontSize: ['hover', 'focus'],
      }
    }
  }

Disabling

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

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