Gastronorm GN Pan Sizes Explained: 1/1, 1/2, 1/3 & 1/4 GN Pan Buying Guide

If you work in a commercial kitchen, catering business, restaurant, hotel, buffet service or food preparation environment, you have probably come across the term GN pan or Gastronorm pan.

At first, the sizing system can seem confusing. What does 1/1 GN mean? Is a 1/2 GN pan half the size of a 1/1 pan? What depth should you choose? And which GN pan size is best for food storage, cooking, buffet service or food preparation?

The good news is that the Gastronorm system was designed to make commercial kitchen equipment work together more efficiently. GN pans can be used with compatible racks, counters, refrigeration equipment, heating equipment, display units and buffet systems.

This guide explains Gastronorm pan sizes, GN pan depths, common applications and how to choose the right GN container for your kitchen.

What Is a Gastronorm GN Pan?

A Gastronorm pan, commonly called a GN pan, is a standardized food container used throughout professional food-service environments.

GN pans are designed around standardized dimensions so that compatible kitchen equipment can accommodate different pan sizes without requiring a completely different system for every application.

They are commonly used for:

• Food preparation
• Cooking
• Food storage
• Refrigeration
• Buffet service
• Food holding
• Ingredient organization
• Catering operations
• Restaurant kitchens
• Hotels and institutional kitchens

Stainless steel GN pans are particularly useful in commercial kitchens because they are durable, reusable and suitable for demanding food-service environments.

For example, HeyHeyShop's SOGA 1/1 GN stainless steel pan is designed around the standard full-size GN format and is suitable for commercial kitchens, buffets, catering and food preparation.

What Does 1/1 GN Mean?

1/1 GN is the standard full-size Gastronorm pan dimension.

The approximate external footprint of a 1/1 GN pan is 53 cm × 32.5 cm, although exact dimensions can vary slightly depending on the manufacturer and construction.

The 1/1 GN size is commonly used as the reference size from which smaller GN formats are derived.

That means a 1/2 GN pan, 1/3 GN pan and other smaller formats are designed to fit within the same overall Gastronorm system.

These dimensions are useful as a general guide. Always check the actual dimensions of your GN pan and the equipment it needs to fit before purchasing.

1/1 vs 1/2 vs 1/3 GN: What's the Difference?

The main difference is the footprint of the pan.

1/1 GN Pan

A 1/1 GN pan is the largest common standard GN format. It is useful when you need to hold or prepare larger quantities of food.

Typical applications include:

• Main buffet dishes
• Large batches of vegetables
• Prepared meats
• Large quantities of pasta
• Food preparation
• Commercial refrigeration
• Catering service

1/2 GN Pan

A 1/2 GN pan occupies roughly half the footprint of a full-size 1/1 GN pan.

It is useful when you need smaller portions or want to divide different foods across a service station.

Common uses include:

• Side dishes
• Vegetables
• Rice
• Smaller food batches
• Sauces
• Buffet service

1/3 GN Pan

A 1/3 GN pan is narrower and works well when you need several ingredients or dishes in the same service area.

It can be particularly useful for sauces, toppings, prepared ingredients and smaller portions.

1/4 GN Pan

Smaller GN formats such as 1/4 GN are useful when portion sizes are limited or when a kitchen needs several different ingredients close together.

Why GN Pan Depth Matters

GN pan size is only part of the decision. Pan depth can be just as important.

The same GN footprint can be available in different depths, allowing you to choose between greater capacity and easier access.

Common depths include approximately:

• 65 mm
• 100 mm
• 150 mm
• 200 mm

Some manufacturers also offer other depths.

Shallow GN Pans

Shallow pans are useful for ingredients and foods that do not require much vertical capacity.

They can also make it easier to access food quickly during busy service.

Medium-Depth GN Pans

Medium-depth pans offer a useful balance between capacity and accessibility.

They can work well for many everyday kitchen applications, including vegetables, cooked foods, sauces and prepared ingredients.

Deep GN Pans

Deep pans are useful when you need to hold larger quantities of food without increasing the footprint of the container.

For example, a 1/1 GN pan with a 200 mm depth provides substantially more vertical capacity than a shallow version of the same footprint.

HeyHeyShop's SOGA 1/1 GN 200 mm deep stainless steel pan is an example of this format.

How to Choose the Right GN Pan Size

The best GN pan is not necessarily the biggest one. Choose the size and depth according to what you actually prepare, store, transport and serve.

1. Consider the Quantity of Food

If you regularly prepare large batches, a full-size GN pan may make sense.

If you serve multiple smaller dishes, several half-size or smaller pans may give you greater flexibility.

2. Consider Your Equipment

Before buying a GN pan, check the dimensions of the equipment where you plan to use it.

Measure or verify compatibility with:

• Commercial refrigerators
• Freezers
• Heated holding cabinets
• Food warmers
• Buffet equipment
• Chafing dishes
• Prep counters
• Storage racks
• Food transport equipment

This is one of the biggest advantages of the Gastronorm system. Standardized sizing allows compatible equipment to be designed around the same container formats.

3. Consider Food Type

Think about the food that will actually go into the pan.

For example:

• Deep foods: Soups, stews and larger quantities may benefit from deeper pans.
• Shallow foods: Roasted vegetables or foods that need easy access may work better in shallower pans.
• Sauces: Smaller GN formats may be easier to manage.
• Ingredients: Smaller pans can help organize prep stations.

4. Consider Service Speed

In a busy kitchen, the best pan is often the one that makes the workflow easier.

A very deep container may hold more food but can be less convenient when staff need to reach the bottom repeatedly.

For fast service, consider both capacity and accessibility.

GN Pans for Catering and Buffet Service

GN pans are particularly useful in catering because they make food preparation, transportation, holding and service more organized.

A catering setup might use:

• Large GN pans for main dishes
• Medium pans for side dishes
• Smaller pans for sauces and toppings
• Shallow pans for foods that need easy access
• Deep pans for higher-volume dishes

GN Pans and Chafing Dishes

GN pans are closely associated with buffet and catering equipment because standardized food containers can work with compatible holding and serving systems.

However, not every GN pan will automatically fit every chafing dish or food warmer.

Always confirm the required pan dimensions, format and depth before purchasing.

GN Pans for Food Preparation

GN pans are not only for serving food.

They can also help organize ingredients during food preparation.

For example, a chef preparing a stir-fry station could organize vegetables, sauces and prepared ingredients in separate containers.

A catering kitchen preparing a large event might use multiple GN pans to separate ingredients by recipe, service time or station.

This can reduce unnecessary movement around the kitchen and make ingredients easier to locate.

GN Pans for Food Storage

Standardized containers can also make storage more organized.

Instead of using a mixture of unrelated containers, a kitchen can use compatible GN sizes to create a more consistent storage system.

When selecting pans for storage, consider:

• Pan dimensions
• Depth
• Stackability
• Lids and covers
• Refrigerator compatibility
• Freezer requirements
• Cleaning requirements
• Frequency of use

HeyHeyShop's stainless steel GN pan design includes stackable construction and reinforced edges, features intended for repeated commercial use.

Why Stainless Steel GN Pans Are Popular

Stainless steel is widely used for commercial food-service containers because it offers a practical combination of durability, cleanability and resistance to corrosion.

Quality stainless steel GN pans can be useful for demanding kitchen environments where containers are washed, moved and reused frequently.

When comparing stainless steel GN pans, look at:

• Material quality
• Construction thickness
• Reinforced corners
• Edge design
• Stackability
• Pan depth
• Compatibility with existing equipment
• Ease of cleaning

How Many GN Pans Do You Need?

There is no universal number because the correct quantity depends on the size and type of your operation.

A small cafe may need a limited selection of pans for prep and service, while a large catering operation may need dozens of containers across multiple stations.

A sensible starting approach is to identify your most frequently prepared foods and assign a suitable GN size to each workflow.

For example:

GN Pan Buying Checklist

Before ordering GN pans, work through this checklist:

• What GN size does your equipment accept?
• What depth do you actually need?
• What foods will be stored or served in the pan?
• Do you need full-size or smaller containers?
• Will the pans be used for cooking, storage, preparation or service?
• Do you need lids?
• Do the pans need to stack efficiently?
• Are the dimensions compatible with your refrigerator or freezer?
• Will they work with your buffet or food-holding equipment?
• Are they durable enough for your workload?

Common GN Pan Buying Mistakes

Mistake 1: Buying Only Based on Capacity

A larger pan is not automatically better.

The pan must fit the equipment and suit the food and workflow.

Mistake 2: Ignoring Depth

Two pans can have the same GN footprint but very different capacities because of their depth.

Mistake 3: Not Checking Equipment Compatibility

Always verify the dimensions of your existing racks, refrigerators, food warmers and serving equipment.

Mistake 4: Buying Too Many Different Sizes

Having many sizes can create flexibility, but an unnecessarily complicated collection can make storage and organization harder.

Start with the sizes that match your most common kitchen tasks.

Mistake 5: Choosing the Cheapest Pan Without Considering Construction

Commercial kitchen containers are handled frequently. Look at construction quality, reinforced edges, stacking design and material rather than comparing price alone.

How GN Pans Can Improve Commercial Kitchen Organization

A well-planned GN system can help standardize how ingredients and prepared foods move through the kitchen.

For example, a restaurant might use one set of pans for ingredient preparation, another for refrigerated storage and another for service.

This creates a more predictable workflow.

GN pans can also work alongside other commercial kitchen equipment such as food service carts and kitchen trolleys, allowing ingredients and prepared food to be moved efficiently between preparation and service areas.

GN Pans vs Regular Food Containers

Regular food containers can be perfectly suitable for many home kitchens. The main advantage of GN pans is standardization.

A standard GN system allows compatible equipment to be designed around known container dimensions.
