Baking pan standards classify cake, brownie, and loaf pans by internal volume and surface area. A 9-inch round cake pan holds 8 cups (1.9 L) with 27% more surface area than an 8-inch round (6 cups / 1.4 L), while standard loaf pans divide into 8.5×4.5" (1 lb loaf) and 9×5" (1.25 lb loaf) formats.

Commercial baking sheet pans are standardized across four fractional sizes: Full Sheet (18×26"), Half Sheet (13×18"), Quarter Sheet (9×13"), and Eighth Sheet (6.5×9.5"), with a 1-inch wire-reinforced rim preventing warping under high thermal shock.
