Gastronorm Pan Sizes vs. Sheet Pans
Comparing 2 standards across 20 specifications. 20 key differences identified.
Comparing:
Gastronorm Pan Sizes
Sheet Pans
The European Standard EN 631 Gastronorm (GN) system defines modular catering pan dimensions based on the GN 1/1 base unit (530 × 325 mm), scaling from GN 2/1 down to GN 1/9 across standardized depths from 20 mm to 200 mm.
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.
