Hello,

You can make the rating stars larger by pasting the below css in Theme Setting >> CUSTOM CSS >> Global Custom CSS:

.star-rating span:before {
 font-size:24px;
}
.star-rating {
font-size:24px;
}

By increasing the font-size rating stars size will also increase.

But it disturbs the ratio of ratings. As the rating stars ratio is calculated with some backend functions and then we are able to see how much rating is given by a person as they filled with yellow color.

It requires customization to change the functionality and formula of calculation of those functions which are responsible for increasing the width of stars and this is beyond our limitations and support policy.

Best Regards.
