Caveats

 * The positioning and perspective makes it hard to compare the character size even in stills.
 * The teenage characters of the show were/are subject to growth, hence their relative and absolute sizes should have changed during the course of time/the show's runtime.
 * Female characters wearing heeled shoes make it very hard to guesstimate their sizes.
