Aww yeah, Material-UI v4 is here!

CircularProgress API

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

import CircularProgress from '@material-ui/core/CircularProgress';


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.


Name Type Default Description
classes object Override or extend the styles applied to the component. See CSS API below for more details.
color enum: '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 union: number |
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 enum: 'determinate' |
 'indeterminate' |
'indeterminate' The variant to use. Use indeterminate when there is no progress value.

Any other properties supplied will be spread to the root element (native element).


You can override all the class names injected by Material-UI thanks to the classes property. This property accepts the following keys:

Name Description
root Styles applied to the root element.
static Styles applied to the root element if variant="static".
indeterminate Styles applied to the root element if variant="indeterminate".
colorPrimary Styles applied to the root element if color="primary".
colorSecondary Styles applied to the root element if color="secondary".
svg Styles applied to the svg element.
circle Styles applied to the circle svg path.
circleStatic Styles applied to the circle svg path if variant="static".
circleIndeterminate Styles applied to the circle svg path if variant="indeterminate".
circleDisableShrink Styles applied to the circle svg path if disableShrink={true}.

Have a look at overriding with classes section and the implementation of the component for more detail.

If using the overrides key of the theme, you need to use the following style sheet name: MuiCircularProgress.
