react hook to clamp multiline text to a given height in a responsive way and with extreme flexibility (under 2.5kb)

Line Clampin’ (Truncating Multiple Line Text) is a major hassle still for most browsers.

This tiny react hook eases that pain.

Why hook?

Cause it gives extreme flexibility over how you want to control the text. Do you want truncate it or not? When to truncate it? How to show read more interactions? and more…


Basic Example

import { useClampText } from 'use-clamp-text';

const longText = "Spicy jalapeno bacon ipsum dolor amet drumstick sirloin chuck shankle. Flank ribeye pancetta andouille ham hock. Turkey cow tenderloin landjaeger filet mignon hamburger. Pig tail strip steak pastrami t-bone venison bresaola biltong corned beef drumstick pork hamburger tri-tip.

Jerky cow short ribs ground round. Hamburger porchetta shankle meatloaf shank.";

function ClampedText {
const [ref, { noClamp, clampedText }] = useClampText({
  text: longText,

  return (
        {noClamp ? 'Not truncated' : 'Truncated'}
