Choosing the right food pan size is important for any commercial kitchen, hotel buffet, restaurant, or catering operation. Whether you are preparing ingredients, storing food, or serving dishes, the correct pan size helps improve kitchen organization and equipment compatibility.
Gastronorm pans, commonly called GN pans or food pans, are widely used in professional foodservice environments because of their standardized dimensions.
But what is the difference between GN 1/1, GN 1/2, and GN 1/3? How deep should a food pan be? And can you use the same GN pans in different commercial kitchen equipment?
This guide provides a complete food pan sizes chart, including GN pan dimensions in millimeters and inches, standard depths, size combinations, and practical buying tips for stainless steel food pans.
What Is a GN Pan?
GN stands for Gastronorm, a standardized system of food container dimensions used in commercial kitchens and catering equipment.
The Gastronorm system originated in Europe and is covered by the EN 631 standard. Its basic unit is the GN 1/1 pan, measuring 530 × 325 mm.
Other GN pan sizes follow a modular design based on this full-size format.
Why Are GN Pan Sizes Standardized?
Standardization makes it easier to use compatible pans across different types of commercial kitchen equipment.
The main benefits include:
- Interchangeability: Pans of compatible specifications can be used with different foodservice equipment.
- Efficient Space Utilization: Different pan sizes can be arranged in standardized equipment openings.
- Easy Food Organization: Suitable for separating ingredients and prepared dishes.
- Flexible Applications: Used in food preparation, storage, cooking, and buffet service.
- Convenient Replacement: Standardized sizes make replacement and inventory planning easier.
GN pans are commonly used with chafing dishes, steam tables, bain-maries, salad bars, refrigerated counters, and compatible commercial ovens.
However, equipment compatibility should always be confirmed using the actual pan dimensions, rim structure, and equipment specifications.
Complete Food Pan Sizes Chart (GN Dimensions in mm and Inches)
GN pans are based on the full-size GN 1/1 module.
The table below shows common Gastronorm pan sizes, including their nominal upper-rim dimensions in millimeters and inches.
| GN Pan Size | Dimensions (L x W in mm) | Dimensions (inches) | Common Applications |
| GN 2/1 | 650 x 530 | 25.6 x 20.9 | Large food service operations |
| GN 1/1 | 530 x 325 | 20.9 x 12.8 | Hotel buffets and steam tables |
| GN 2/3 | 354 x 325 | 13.9 x 12.8 | Buffet service and food preparation |
| GN 1/2 | 325 x 265 | 12.8 x 10.4 | Side dishes and buffet stations |
| GN 1/3 | 325 x 176 | 12.8 x 6.9 | Salad bars and ingredient stations |
| GN 2/4 | 530 x 162 | 20.9 x 6.4 | Narrow food display arrangements |
| GN 1/4 | 265 x 162 | 10.4 x 6.4 | Condiments and smaller portions |
| GN 1/6 | 176 x 162 | 6.9 x 6.4 | Toppings and sauces |
| GN 1/9 | 108 x 176 | 6.9 x 4.3 | Garnishes and small ingredients |
Note: These are nominal external dimensions measured at the upper rim. Actual dimensions may vary within manufacturing tolerances. Always check your equipment specifications before ordering.
What Do GN 1/1, GN 1/2, and GN 1/3 Mean?
The numbers describe the approximate modular footprint of each pan relative to GN 1/1.
For example:
- GN 1/1: One full-size Gastronorm pan.
- GN 1/2: Two half-size pans occupy one full-size module.
- GN 1/3: Three one-third pans occupy one full-size module.
- GN 1/4: Four quarter-size pans occupy one full-size module.
- GN 1/6: Six one-sixth pans occupy one full-size module.
- GN 1/9: Nine one-ninth pans occupy one full-size module.
This modular system gives commercial kitchen operators flexibility when organizing dishes and ingredients.
Which GN Pan Size Is Most Common?
GN 1/1 is the standard full-size reference used in many commercial foodservice systems.
GN 1/2 and GN 1/3 pans are also popular for buffet service and ingredient preparation because they allow different foods to be arranged within a limited space.
The best size depends on the equipment, food volume, and serving requirements.
GN Pan Size Combinations: How Do Different Food Pans Fit Together?
One advantage of the Gastronorm system is that several smaller food pans can be arranged within a full-size GN 1/1 footprint.
Common arrangements include:
| GN Pan Combination | Full-Size GN 1/1 Footprint |
|---|---|
| 1 × GN 1/1 | One full-size pan |
| 2 × GN 1/2 | Two half-size pans |
| 3 × GN 1/3 | Three one-third pans |
| 4 × GN 1/4 | Four quarter-size pans |
| 6 × GN 1/6 | Six one-sixth pans |
| 9 × GN 1/9 | Nine one-ninth pans |
| 1 × GN 1/2 + 2 × GN 1/4 | Mixed-size arrangement |
These combinations are useful in buffet stations, salad bars, food preparation counters, and commercial serving equipment.
For example, a buffet operator may use one full-size pan for a main dish or divide the available space into smaller sections to serve different foods.
Important: Some equipment requires divider bars, adapters, or specific pan supports when using smaller GN pans. Check equipment compatibility before changing pan configurations.
Standard GN Pan Depths Explained
Besides length and width, GN pan depth is another important factor when choosing a food pan.
Pans with the same GN size can have different depths, allowing operators to select a suitable container for food presentation, preparation, or storage.
Common GN Pan Depth Chart
| Depth (mm) | Depth (inches) | Typical Applications |
|---|---|---|
| 20 mm | 0.8 in | Shallow food presentation |
| 40 mm | 1.6 in | Cold dishes and small portions |
| 65 mm | 2.6 in | Buffet service and food preparation |
| 100 mm | 3.9 in | Food holding and general preparation |
| 150 mm | 5.9 in | Larger portions and food storage |
| 200 mm | 7.9 in | Bulk storage and food preparation |
Available depths may vary depending on the manufacturer, GN size, and product series.
How to Choose the Right GN Pan Depth
20–40 mm: Shallow Food Pans
Suitable for food displays, smaller portions, and applications requiring easy access to the contents.
65–100 mm: Medium-Depth Food Pans
Commonly selected for buffet service, ingredient preparation, and general food holding.
150–200 mm: Deep Food Pans
Useful for larger food quantities and bulk preparation, provided the equipment has sufficient clearance.
Deeper pans offer more volume, but they are not automatically the best choice for every application. Consider equipment clearance, food quantity, heating method, and serving frequency.
Where Are GN Pans Used?
Because of their standardized dimensions, Gastronorm pans are used in many commercial foodservice environments.
Hotel Buffets and Restaurants
Stainless steel GN pans are widely used in buffet stations and chafing dishes.
Full-size pans can hold larger dishes, while smaller pans make it possible to serve several different foods within one buffet station.
Catering and Event Services
GN pans help organize prepared food and can be used with compatible catering equipment.
Selecting the right size and depth helps operators manage different menu items and serving quantities.
Commercial Kitchen Preparation
GN pans are convenient for separating ingredients, preparing recipes, and organizing food during kitchen operations.
Refrigerated Preparation Counters
Smaller pans, including GN 1/3, GN 1/6, and GN 1/9, are commonly used to organize toppings, vegetables, sauces, and other ingredients.
Commercial Ovens and Steamers
Suitable stainless steel GN pans can be used in compatible cooking equipment. Always verify the pan’s material, construction, temperature limits, and equipment requirements.
GN Pans vs. American Hotel Pans: What Is the Difference?
GN pans and hotel pans are closely related, but buyers should not assume that every product uses identical dimensions.
The Gastronorm system follows standardized modular dimensions, with GN 1/1 measuring 530 × 325 mm.
In North America, food pans are often described using names such as:
- Full-size hotel pan
- Half-size hotel pan
- Third-size hotel pan
- Quarter-size hotel pan
- Sixth-size hotel pan
- Ninth-size hotel pan
Some American-style hotel pans have dimensions or rim designs that differ from European GN pans.
When sourcing food pans for different markets, buyers should confirm:
- Nominal external dimensions.
- Upper-rim and corner design.
- Available depths.
- Compatibility with existing equipment.
- Matching lids and divider bars.
Buying Tip: The terms “full size” and “half size” alone may not provide enough information for international orders. Always request a detailed dimensional specification.
Stainless Steel GN Pans: 201 vs. 304 Material
Stainless steel is commonly used for GN pans because it is durable, easy to clean, and suitable for a wide range of commercial kitchen applications.
Two commonly encountered grades are 201 and 304 stainless steel.
201 vs. 304 Stainless Steel Comparison
| Feature | 201 Stainless Steel | 304 Stainless Steel |
|---|---|---|
| Corrosion Resistance | Generally lower | Generally higher |
| Nickel Content | Generally lower | Generally higher |
| Material Cost | Usually lower | Usually higher |
| Typical Buying Priority | Cost and intended conditions | Corrosion resistance and demanding use |
| Food-Contact Suitability | Depends on the finished product and applicable requirements | Depends on the finished product and applicable requirements |
Which Stainless Steel Grade Should You Choose?
304 stainless steel generally offers better corrosion resistance, making it a common choice for foodservice applications involving moisture and frequent cleaning.
201 stainless steel may also be considered for certain applications, depending on the operating environment, product design, and relevant food-contact requirements.
For wholesale buyers, material selection should consider the intended market, food-contact compliance, product thickness, manufacturing quality, and actual operating conditions.
The material grade alone does not establish food-contact certification or guarantee a specific service life.
Solid vs. Perforated GN Pans
In addition to dimensions and materials, GN pans are available with different bottom designs.
Solid GN Pans
Solid food pans have a continuous bottom and are suitable for holding food, ingredients, sauces, and other contents that require liquid retention.
Common applications include food storage, buffet service, ingredient preparation, and compatible hot food holding equipment.
Perforated GN Pans
Perforated food pans feature drainage holes that allow water or steam to pass through.
They are commonly used for steaming, draining, and selected food preparation processes.
When ordering perforated GN pans, buyers should verify the hole pattern, dimensions, material, and compatibility with their equipment.
How to Choose the Right GN Pan for Your Kitchen
Choosing a suitable food pan involves more than selecting its length and width.
Here are five important points to consider.
1. Check Your Equipment Dimensions
Confirm whether your equipment uses European GN dimensions, American-style hotel pans, or another pan format.
2. Choose the Appropriate GN Size
Full-size pans are suitable for larger food quantities, while smaller pans help organize different dishes and ingredients.
3. Select a Suitable Depth
Consider food quantity, equipment clearance, preparation requirements, and serving method.
4. Compare Material and Construction
Evaluate stainless steel grade, thickness, rim structure, surface finish, and manufacturing quality.
5. Confirm Accessories and Pan Combinations
Check whether the equipment requires matching lids, divider bars, or additional supports.
For hotel equipment distributors and commercial kitchen suppliers, confirming these details before ordering can help reduce product mismatches.
Cleaning and Maintenance Tips for Stainless Steel GN Pans
Proper cleaning and maintenance help keep stainless steel food pans in good condition.
- Remove food residues promptly after use.
- Wash with a suitable detergent and clean water.
- Avoid harsh abrasives that may damage the finish.
- Rinse and dry thoroughly before storage.
- Follow the manufacturer’s instructions for dishwasher use.
- Inspect pans regularly for deformation, corrosion, or damage.
- Avoid prolonged contact with aggressive cleaning chemicals.
Cleaning requirements may vary depending on the stainless steel grade, surface finish, and foodservice environment.
