"star ratings" size changes?

Hello! Our mission center utilizes Knack for volunteer registration (and much more). Volunteers use the “star ratings” to communicate their skill levels to us. We gauge their skills in about 15 different areas.

The star rating fields are quite large - and to have 15 columns with star ratings makes for a very large page for our staff to evaluate… I’ve toyed around with making the stars smaller, and the stars may be smaller but the column size doesn’t really change.

I am seeking ideas for either 1) Changing the star size or 2) more creative and condensed methods for showing the skils of each participant. Thanks so much!!
