Diameter is a capacity rating rather than a suggestion. Overfilling a comb splays the tines so the document will not close and pages fall out of the punch holes within a week. Count the sheets including covers, then choose the next size up if it is close. Colour is cosmetic; pitch has to match the machine. See plastic binding combs, comb binding machines and binding covers.
