The 13" (WDA13) is suited for narrower merchandise — small accessories, beauty products, packaged goods where a 15" deep shelf would be unnecessarily deep. The 15" (WDA15) accommodates deeper merchandise — standard retail packaged goods, folded apparel, and items where a 13" shelf would leave products overhanging the front edge. Choose shelf depth based on the depth of your deepest merchandise, with 1-2" of clearance at the back.
