CircularProgress API

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

Import

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

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

ARIA

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.

Component name

The MuiCircularProgress name can be used for providing default props or style overrides at the theme level.

Props

Name Type Default Description
classes object Override or extend the styles applied to the component. See CSS API below for more details.
color 'inherit'
| 'primary'
| 'secondary'		 'primary' The color of the component. It supports those theme colors that make sense for this component.
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 circle. If using a number, the pixel unit is assumed. If using a string, you need to provide the CSS unit, e.g '3rem'.
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.

The ref is forwarded to the root element.

Any other props supplied will be provided to the root element (native element).
