Progress

Import

import CircularProgress from '@mui/material/CircularProgress';
// or
import { CircularProgress } from '@mui/material';

Learn about the difference by reading this guide on minimizing bundle size.

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.

Props

Props of the native component are also available.

Name	Type	Default	Description
classes	object	-	Override or extend the styles applied to the component. See CSS classes API below for more details.
color	'inherit' \| 'primary' \| 'secondary' \| 'error' \| 'info' \| 'success' \| 'warning' \| string	'primary'	The color of the component. It supports both default and custom theme colors, which can be added as shown in the palette customization guide.
disableShrink	bool	false	If `true`, the shrink animation is disabled. This only works if variant is `indeterminate`.
size	number \| string	40	The size of the component. If using a number, the pixel unit is assumed. If using a string, you need to provide the CSS unit, for example '3rem'.
sx	Array<func \| object \| bool> \| func \| object	-	The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.
thickness	number	3.6	The thickness of the circle.
value	number	0	The value of the progress indicator for the determinate variant. Value between 0 and 100.
variant	'determinate' \| 'indeterminate'	'indeterminate'	The variant to use. Use indeterminate when there is no progress value.
