CircularProgress API

The API documentation of the CircularProgress React component. Learn more about the props and the CSS customization points.


import CircularProgress from '@material-ui/core/CircularProgress';
// or
import { CircularProgress } from '@material-ui/core';

You can learn more about the difference by reading our guide.


If the progress bar is describing the loading progress of a particular region of a page, you should use aria-describedby to point to the progress bar, and set the aria-busy attribute to true on that region until it has finished loading.
