Gastronorm sizes

Gastronorm is a standardized dimension used in the catering industry to describe the size of kitchen utensils, appliances, and containers. The Gastronorm standard, often abbreviated as "GN", is widely adopted in professional kitchens and catering establishments around the world. It ensures compatibility and interchangeability between equipment made by different manufacturers, facilitating a more efficient and organized kitchen environment.

This standardization was intended to make the storage, preparation, cooking, and presentation of food more systematic and efficient. Since its introduction, the Gastronorm standard has been adopted internationally, becoming a fundamental aspect of commercial kitchen design and operation.
