Hover feedback

You can display a label on hover to help users pick the correct rating value. The demo uses the onChangeActive prop.

  onChange={(event, newValue) => {
  onChangeActive={(event, newHover) => {
{value !== null && <Box ml={2}>{labels[hover !== -1 ? hover : value]}</Box>}

Half ratings

The rating can display any float number with the value prop. Use the precision prop to define the minimum increment value change allowed.

<Rating name="half-rating" defaultValue={2.5} precision={0.5} />
<Rating name="half-rating-read" defaultValue={2.5} precision={0.5} readOnly />


Fancy larger or smaller ratings? Use the size prop.

<Rating name="size-small" defaultValue={2} size="small" />
<Rating name="size-medium" defaultValue={2} />
<Rating name="size-large" defaultValue={2} size="large" />


(WAI tutorial:

The accessibility of this component relies on:

  • A radio group is used with its fields visually hidden. It contains six radio buttons, one for each star and another for 0 stars, which is checked by default. Make sure you are providing a name prop that is unique to the parent form.
  • The labels for the radio buttons contain actual text (“1 Star”, “2 Stars”, …), make sure you provide a getLabelText prop when the page language is not English.
