Textarea Autosize

The Textarea Autosize component gives you a textarea HTML element that automatically adjusts its height to match the length of the content within.


Textarea Autosize is a utility component that replaces the native <textarea> HTML.

The height of the Textarea Autosize component automatically adjusts as a response to keyboard inputs and window resizing events.



After installation, you can start building with this component using the following basic elements:

import TextareaAutosize from '@mui/base/TextareaAutosize';

export default function MyApp() {
  return <TextareaAutosize />;


Textarea Autosize behaves similarly to the native HTML<textarea>.

By default, an empty Textarea Autosize component renders as a single row, as shown in the following demo:
