How to Use Tailwind Line Clamp for Text Truncation

Truncating text to a specific number of lines is a common design requirement in web development. It helps maintain a clean and uniform layout, especially when dealing with dynamic content. Tailwind CSS, a utility-first CSS framework, provides a simple and effective solution for this called “line clamp.” In this comprehensive guide, we’ll explore how to use Tailwind’s line clamp utility to control text overflow in your projects.

Understanding Line Clamp

Before diving into the implementation, let’s understand what line clamp is. Line clamping is a technique used to limit the number of lines that a block of text can occupy. Any text that exceeds the specified limit is truncated, and an ellipsis (...) is typically added to indicate that there is more text that isn’t being displayed.


To use Tailwind’s line clamp utility, you should have the following:

  • Basic knowledge of HTML and CSS
  • A project set up with Tailwind CSS version 2.0 or higher

If you’re new to Tailwind CSS, you can learn how to set it up by visiting the official Tailwind CSS installation guide.

Enabling Line Clamp in Tailwind CSS

As of Tailwind CSS v2.0, the line clamp utility is not enabled by default. To use it, you need to enable it in your tailwind.config.js file. Here’s how:

// tailwind.config.js
module.exports = {
  // ...
  plugins: [

Make sure you have installed the @tailwindcss/line-clamp plugin before adding it to your configuration. You can install it using npm or yarn:

npm install @tailwindcss/line-clamp
# or
yarn add @tailwindcss/line-clamp

Using Tailwind Line Clamp

Once you have the plugin enabled, you can start using the line clamp utility in your HTML. Tailwind provides a set of predefined classes for clamping text from 1 to 6 lines. Here’s how to use them:

<!-- Clamp text to 1 line -->
<p class="line-clamp-1">This is some long text that will be truncated after one line.</p>

<!-- Clamp text to 2 lines -->
<p class="line-clamp-2">This is some long text that will be truncated after two lines.</p>

<!-- Clamp text to 3 lines -->
<p class="line-clamp-3">This is some long text that will be truncated after three lines.</p>

<!-- ...and so on up to 6 lines -->

Customizing Line Clamp

If you need to clamp text to more than 6 lines, you can extend the default Tailwind configuration by adding your own custom line clamp utilities. Here’s an example of how to add a utility for clamping text to 8 lines:

// tailwind.config.js
module.exports = {
  // ...
  theme: {
    extend: {
      lineClamp: {
        '8': '8',
  plugins: [

After extending the configuration, you can use your custom class like this:

<!-- Clamp text to 8 lines -->
<p class="line-clamp-8">This is some long text that will be truncated after eight lines.</p>

Cross-Browser Compatibility

The line clamp utility relies on the CSS line-clamp property, which is part of the CSS Overflow Module Level 3. As of early 2023, it is widely supported in modern browsers, but there might be some compatibility issues with older browsers. You can check the current browser support on Can I use.


Tailwind’s line clamp utility is a powerful tool for managing text overflow in a clean and responsive way. By following this guide, you should now be able to implement text truncation effectively in your Tailwind CSS projects. Remember to always check for browser compatibility and to extend your configuration when necessary to meet your design requirements.
