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';

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.

Props

Name	Type	Default	Description
classes	object		Override or extend the styles applied to the component. See CSS API below for more details.
color	'primary' | 'secondary' | 'inherit'	'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.
thickness	number	3.6	The thickness of the circle.
value	number	0	The value of the progress indicator for the determinate and static variants. Value between 0 and 100.
variant	'determinate' | 'indeterminate' | 'static'	'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).

You can override the style of the component thanks to one of these customization points:

• With a rule name of the classes object prop.
• With a global class name.
• With a theme and an overrides property.

If that's not sufficient, you can check the implementation of the component for more detail.

Notes

The component is fully StrictMode compatible.
