Many customers are concerned with choosing the appropriate size Gapper®. We offer a size guarantee, so if you find your Gapper® is not the correct size, contact us at info@trumpetgapper.com

Generally speaking, if you have large hands, choose an XL or L Gapper®. If you have small hands, choose an XS or S Gapper®. Sizes correspond to ring size in roughly the following way:
