Gastronorm (GN) Pan Sizes Guide & Layout Planner

Gastronorm (GN) Pan Sizes

Gastronorm is the European standard (EN 631) for kitchen pans and containers. Every size is a fraction of the GN 1/1 footprint, so pans fit together in ovens, bain-maries, fridges and display counters.

Size chart

Standard depths: 20, 40, 65, 100, 150 and 200 mm. Dimensions are outer (flange) sizes.

Layout planner

See how pans combine to fill one GN 1/1 space. Pick a size to highlight where it fits.

Capacity estimator

Estimates are for a full pan to the brim; working capacity is typically 10-20% less. Exact volumes vary by manufacturer and pan design.

Quick tips

• GN 2/1: large combi ovens and bulk prep.
• GN 1/1: the standard unit for ovens, hot cupboards and fridges.
• GN 1/2 to 1/9: bain-marie and buffet wells, salad bars and toppings.
• Depth: 20-40 mm for roasting and baking, 65 mm for general service, 100 mm and over for soups, sauces and storage.
• Always match pan size to the well or oven rack; lids and adaptor bars follow the same fractions.
