Comparing 2 standards across 15 specifications. 15 key differences identified.

Comparing:
Sheet Pans
Skillets & Frying Pans

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.

Skillets and frying pans are measured across their top outer rim diameter (8", 10", 12", 14"), with flared sidewalls reducing the usable flat cooking base by approximately 2 to 2.5 inches relative to the nominal rim diameter.
