Gastronorm sizes are standardised container sizes introduced by the European Standards Committee across the food service and catering industry. It allows commercial kitchen equipment manufacturers to optimise their designs to accommodate these standardised pan sizes.
This, in turn, makes purchasing commercial catering equipment easier for chefs and kitchen managers. These European standard sizes are also referred to as GN sizes. In this article, we talk about all the sizes that conform to the EU Standard EN631, as well as the many different uses and materials available.
