Radio group item sizing

Is there a way to re-size radio group items? I know you can adjust component items margins and padding in the theme settings, but I wonder if you can make more adjustments to the size. It looks pretty odd to have such large items with only one word items in the radio group (see screenshot).

Have you tried setting 3 items per row in Appearance settings? An alternative might be to resize the component as half width.

Thanks for your ideas; a combination of resizing to half width and using 3 columns is an improvement.
