GN Pan Size Guide: Gastro Norm Dimensions, Depths & Compatibility Explained
GN Pan Size Guide: Gastro Norm Dimensions, Depths & Compatibility Explained What Is a GN Pan? GN stands for Gastronorm — a European standardisation system for food service container dimensions that has been universally adopted across commercial kitchens worldwide. The standard is defined under EN 631 (and its predecessor DIN 66075), and it establishes fixed external dimensions for pans, lids, frames and equipment apertures. The genius of the Gastronorm system is interoperability. A GN 1/2 pan from any manufacturer will fit in a bain marie, combi oven, blast chiller, cold well or hotel pan rack from any other manufacturer — because the external dimensions are fixed by the standard. This makes planning, purchasing, and expanding a commercial kitchen significantly simpler. GN 1/1 is the base unit. All other sizes are fractions of 1/1 and are designed to tile together to fill a 1/1 aperture. A 1/2 + a 1/2 = one 1/1. Two 1/3s + one 1/3 = one 1/1. And so on. Standard Gastro Norm Sizes The following are the standard GN sizes with their external dimensions as defined by EN 631. These are the standardised figures — if a manufacturer quotes different external dimensions, the pan is not EN 631 compliant and may not fit standard equipment. GN Size External Dimensions (W × D mm) Fraction of GN 1/1 Notes GN 1/1 530 × 325 mm Full size The base unit; fits all full-size equipment apertures GN 2/3 354 × 325 mm 2/3 of 1/1 Two fit side-by-side to fill a 1/1 wide aperture (with a 1/3) GN 1/2 265 × 325 mm 1/2 of 1/1 Two 1/2 pans fit side-by-side to fill a 1/1 aperture GN 1/3 176 × 325 mm 1/3 of 1/1 Three fit side-by-side across a 1/1 aperture GN 2/4 (1/2 long) 530 × 162 mm 1/2 of 1/1 (lengthwise) Less common; used in some linear bain marie configurations GN 1/4 265 × 162 mm 1/4 of 1/1 Two fit across the short dimension of a 1/1; popular for sauces and garnishes GN 1/6 176 × 162 mm 1/6 of 1/1 Six fit in a 1/1 aperture; suits condiments, small portion service, cold wells GN 1/9 176 × 108 mm 1/9 of 1/1 Nine fit in a 1/1 aperture; very small; best for garnishes, sauces, condiments GN Pan Dimensions Chart GN Size External Dimensions (W × D mm) Approximate Internal Dimensions Count in GN 1/1 Typical Use GN 1/1 530 × 325 mm ~507 × 305 mm (at 65mm depth) 1 Full portions, roasting, baking, batch cooking, pasta, buffet service GN 2/3 354 × 325 mm ~334 × 305 mm 1.5 (two 2/3 + one 1/3 or similar combination) Medium portions, side dishes, sauces, combi oven use GN 1/2 265 × 325 mm ~244 × 305 mm 2 Versatile all-rounder; bain marie service, oven, cold well, prep storage GN 1/3 176 × 325 mm ~156 × 305 mm 3 Sauces, vegetables, buffet service, cold well garnishes GN 1/4 265 × 162 mm ~244 × 145 mm 4 Sauces, condiments, small portions, hotel pan racks GN 1/6 176 × 162 mm ~156 × 145 mm 6 Condiments, small sauces, prep mise en place, deli display GN 1/9 176 × 108 mm ~156 × 90 mm 9 Garnishes, small condiments, sauces at service; not suited for storage volumes Internal dimensions vary by manufacturer and depth. External dimensions are fixed by EN 631 — this is what determines fit in equipment. Internal dimensions vary slightly based on wall thickness and depth. Always verify internal volume specs if you're loading by weight or volume for portioning. GN Pan Depth & Capacity Comparison GN pans are available in multiple depths, each suited to different applications. Depth is critical — the wrong depth for your combi oven or bain marie can mean the pan doesn't sit in the runners, lids don't fit, or you overflow product. Depth Designation Actual Depth Volume — GN 1/1 (approx.) Volume — GN 1/2 (approx.) Primary Use Case 20mm 20mm ~3L ~1.5L Lids with depth, display trays, very shallow applications 40mm 40mm ~6L ~3L Shallow serving, buffet garnishes, sauces, baking (some applications) 65mm 65mm ~10L ~5L The most common depth. Bain marie service, standard combi oven, cold well, general storage 100mm 100mm ~15L ~7.5L Deeper portions, soups, stews, batch cooking, larger combi oven loads 150mm 150mm ~22L ~11L Deep storage, bulk prep, proteins marinating, bulk sauce 200mm 200mm ~28L ~14L Large-batch storage only; typically too deep for active cooking applications Check your combi oven runner spacing before specifying depth. Most combi ovens accept 65mm pans on standard runners. 100mm pans typically require every second runner position to be used. 150mm and 200mm pans may require removal of multiple runners. Confirm with your oven manual before ordering deep GN pans. Equipment Compatibility Guide Equipment Type Compatible GN Sizes Compatible Depths Notes Combi Oven (full size) 1/1, 1/2, 2/3, 1/3 40–100mm standard; 150mm possible (check runner spacing) Pan width must not exceed oven rail width — confirm specifications per oven model Bain Marie (wet or dry) 1/1, 1/2, 1/3, 1/4, 1/6, 1/9 65mm most common; 100mm in deep models Pan must sit in the aperture with 20–30mm lip for support — verify frame size Blast Chiller / Freezer 1/1, 1/2, 2/3 40–65mm for fastest chilling; shallower = faster temperature drop Shallower pans chill faster; maximum load depth is critical for food safety compliance (HACCP) Cold Well / Salad Bar 1/1, 1/2, 1/3, 1/4, 1/6 65–100mm typical Drain placement at base of cold well affects pan fit — confirm aperture dimensions Salamander / Oven Tray Rack 1/1, 1/2, 2/3 20–65mm recommended Deep pans increase distance from heating element — check clearance for even cooking GN Pan Rack / Storage Trolley All sizes (rack-dependent) All depths Rack runner spacing must match pan depths; mixed-depth use typically requires rack adjustment Common Buying Mistakes Mixing brands with different tolerances: While external dimensions are standardised, some budget manufacturers produce pans that are fractionally out of spec — just enough to bind or rattle in equipment runners. Buy EN 631-compliant pans from reputable commercial suppliers and stick to consistent brands within your operation. Buying the wrong depth for your combi oven: The most common GN mistake. Check your oven's runner spacing against the pan depth, not just the pan size designation. A 100mm GN 1/1 pan in an oven designed for 65mm will either not fit or will occupy two runner positions. Confusing pan size with lid size: GN lids are made for specific pan depths. A lid designed for a 65mm pan will not create a proper seal on a 100mm pan. Always match lid depth to pan depth. Ordering 1/9 pans expecting useful storage volume: GN 1/9 pans are for service — garnishes and condiments. At 150mm depth they hold roughly 1.5L. They're not suited to prep storage. Not stocking the right mix: Most kitchens need a mix of sizes. The most versatile mix for a new kitchen: GN 1/1 × 65mm and 100mm, GN 1/2 × 65mm, GN 1/3 × 65mm, and a selection of 1/6 for bain marie service. Add others based on your specific equipment and menu.

Commercial Dishwasher Size Guide: Choosing the Right Machine for Your Venue
Commercial Dishwasher Size Guide: Choosing the Right Machine for Your Venue The right commercial dishwasher keeps your service running. The wrong one creates bottlenecks, breakages, unhappy staff and a mountain of handwashing in the middle of a busy service. Before you spec a machine, you need to know two things: how much ware you need to turn over per hour, and what space you have to put the machine in. Dishwasher Types and Their Capacity Commercial dishwashers fall into three main categories, each suited to different throughput volumes and kitchen configurations: Underbench / Glasswasher These are compact machines that fit under a standard 900mm bench. They handle one rack at a time with a door that opens on the front. Cycle times are typically 90–120 seconds. Best for low-to-medium volume operations where floor space is constrained. Note that glasswashers use lower temperatures and gentler cycles than full dishwashers — don't use a glasswasher for food-contact plates if it's not rated for sanitising temperatures. Pass-Through / Hood-Type The industry workhorse. A rack slides into the machine, the hood comes down, the cycle runs (typically 60–120 seconds), and the rack comes out the other side onto a clean staging table. Staff load one end, unload the other — efficient, fast and ergonomic when set up correctly. Requires inlet and outlet benching space either side. For a deep-dive on pass-through dishwashers, see our guide: The Ultimate Guide to Commercial Pass-Through Dishwashers. Conveyor / Rack Conveyor For high-volume operations — large hotels, universities, event catering, hospitals. Racks move continuously through a tunnel-style machine. Output can exceed 250+ racks per hour. These are major infrastructure investments and require significant space and utility provisions (3-phase power, hot water, drain capacity). Wash temperature matters for compliance. Under Australian food safety standards (Standard 3.2.2), equipment used in contact with food must be effectively sanitised. Most commercial dishwashers achieve this via high-temperature sanitising cycles (final rinse 82–85°C at the rack surface) or chemical sanitising. Confirm your machine meets the requirements for your state health authority. Capacity Comparison Table Machine Type Racks / Hour Covers / Hour Equivalent Ideal Venue Size Footprint (approx.) Price Tier (AUD) Glasswasher (underbench) 20–40 Up to 40 covers Small bar, café, kiosk 430–600mm W × 500mm D × 850mm H $1,500–$3,500 Underbench Dishwasher 20–30 Up to 60 covers Small café, takeaway, food truck 600mm W × 600mm D × 850mm H $2,500–$5,000 Pass-Through (mid-range) 40–60 60–120 covers Café, bistro, pub kitchen 600–660mm W × 700mm D × 1,450mm H (hood up) $5,000–$12,000 Pass-Through (high-capacity) 60–100 120–200 covers Full-service restaurant, club, hotel 660–720mm W × 750mm D × 1,500mm H (hood up) $10,000–$20,000 Conveyor / Rack Conveyor 150–350+ 300–700+ covers Hotels, catering, institutional 3,000–6,000mm L × 800mm W (varies) $30,000–$80,000+ How to Calculate Your Throughput Requirements Here's the working formula: Determine covers per service: Use your peak service period (e.g. 120 covers in a 2-hour dinner service) Estimate items per cover: Count all plates, bowls, glasses, cutlery pieces per setting. A typical restaurant cover = 2–3 plates + 2–3 glasses + full cutlery set ≈ 8–12 pieces per cover Calculate pieces per hour: 120 covers × 10 pieces = 1,200 pieces over 2 hours = 600 pieces/hour Convert to racks per hour: A standard commercial rack holds approximately 25 plates, or 36 glasses. Mixed loads average ~20–25 pieces. 600 pieces ÷ 20 pieces per rack = 30 racks/hour Add a buffer: Add 20–30% for re-washes, peaks in the service, and handover time between racks. 30 × 1.25 = 38 racks/hour minimum machine capacity Don't forget pot wash. If your pots and pans go through the same machine, add volume for those separately. Bulky pots reduce effective rack capacity and require longer pre-rinse time. High-volume operations often have a dedicated pot wash sink alongside the main dishwasher. Water and Chemical Usage Comparison Machine Type Water per Rack (L) Energy per Rack (kWh) Chemical Cost Indicator Notes Underbench glasswasher 2.5–4L 0.05–0.10 Low Low water volume suits glass-only operation Underbench dishwasher 3–5L 0.10–0.18 Low–Medium Uses detergent + rinse aid; check booster heater sizing Pass-through (standard) 2.5–4L 0.15–0.25 Medium Most efficient per-rack water use at this tier Pass-through (heat recovery) 2.5–3.5L 0.10–0.18 Medium Heat recovery condenser reclaims energy from exhaust steam — reduces energy costs 20–30% Conveyor 0.8–1.5L 0.05–0.12 High (volume) Best per-rack water/energy efficiency at scale; high absolute consumption due to throughput For venues on water restrictions or high utility tariffs, a pass-through with heat recovery condenser can pay for the premium in utility savings within 12–18 months at moderate throughput. For more on maintaining your machine, see: Should I Get My Commercial Dishwasher Serviced? Why It's Worth It. Common Sizing Mistakes Sizing to average throughput, not peak: Your machine has to handle the dinner rush, not Tuesday lunch. Calculate for peak service and add your buffer on top of that. Ignoring staging bench space: A pass-through dishwasher without adequate soiled inlet table and clean outlet table creates immediate bottlenecks. Allow minimum 900mm each side; 1,200mm preferred. Without it, clean ware and soiled ware clash and staff can't keep up. Underspecifying the hot water supply: Commercial dishwashers draw large volumes of hot water rapidly. If your hot water system can't maintain supply temperature, wash performance and sanitisation effectiveness both drop. Confirm the incoming water temperature and flow rate against machine specs. Buying a glasswasher for a full kitchen: Glasswashers use gentler cycles and lower temperatures — they're not a substitute for a commercial dishwasher for plates and kitchen ware. Not checking drain height compatibility: Some pass-through models drain at a specific height that may not match your existing floor waste configuration. Confirm drain specs before purchase. What to Look for When Buying Cycle time: Shorter cycles improve throughput but require adequate hot water recovery. Check manufacturer-stated racks/hour under continuous operation. Heat recovery condenser: Worth the premium for any machine doing 50+ racks/day. Reduces steam in the kitchen and energy costs. Self-cleaning programs: Machines with automatic descaling and self-clean programs reduce maintenance labour and extend service life. Chemical dosing pump integration: Built-in peristaltic pumps for detergent and rinse aid ensure consistent dosing and reduce waste. Rack compatibility: Check rack dimensions are compatible with your existing ware if you're replacing an existing machine. Standard racks are 500×500mm — most machines are compatible, but confirm. Service agent availability: Dishwashers are mission-critical equipment. Confirm your chosen brand has service agents in your area with parts in stock.

Commercial Refrigerator Size Guide: What Fridge Capacity Does Your Kitchen Need?
Commercial Refrigerator Size Guide: Choosing the Right Capacity for Your Kitchen Choosing the wrong commercial refrigerator capacity is one of the most expensive mistakes you can make in a kitchen fitout. Too small and you're cramming product, compromising food safety, and making multiple runs to cold storage mid-service. Too large and you're paying to refrigerate dead air and occupying valuable kitchen floor space. This guide explains how to read capacity specifications, match fridge types to use cases, and calculate what you actually need. Commercial Fridge Capacity Explained Commercial refrigerator capacity is typically expressed in litres (L) in Australia. You'll occasionally see cubic feet (cu ft) on imported product specs — 1 cu ft ≈ 28.3 litres. Gross capacity vs net capacity: Gross capacity: The total internal volume of the cabinet. This is the number most commonly quoted in marketing specs. Net (usable) capacity: The actual usable space after accounting for shelving, evaporator coils, fans and internal fittings. Net capacity is typically 65–80% of gross capacity. Always compare net capacity, not gross. A fridge advertised at 600L gross might deliver only 380–420L of usable shelf space. When comparing models, ask for the net capacity figure or count the usable shelf area. For food safety and temperature compliance, see our guide to commercial fridge temperature requirements. Refrigerator Types and Their Use Cases Type Capacity Range Best For Footprint Underbench Refrigerator 60–250L Below prep bench or bar; supplementary cold storage; ingredient access at the station 600–900mm W × 600–700mm D × 850mm H Upright 1-Door 300–600L Small kitchens, cafés, bakeries; general ingredient storage 600–700mm W × 600–700mm D × 1,850–2,000mm H Upright 2-Door 900–1,400L Restaurants, hotels, institutional kitchens; primary cold storage 1,200–1,400mm W × 700mm D × 1,900–2,100mm H Upright Glass Door 300–1,200L Front-of-house display, beverage fridges, retail display As per solid door equivalents Prep / Saladette Fridge 200–600L Pizza prep, salad bars, sushi prep — cold storage + accessible prep surface in one unit 1,000–2,000mm W × 700mm D × 850–900mm H (surface) Display / Deli Fridge 200–800L Retail display, grab-and-go, café counter display 900–2,000mm W × 600–700mm D × 1,200–1,500mm H Capacity Comparison Table Net Capacity (L) Estimated Cover Capacity Typical Venue Type Approx. Dimensions (W × D × H) 80–150L Up to 20–30 covers Small café, food truck, kiosk 600 × 600 × 850mm (underbench) 200–350L 30–60 covers Café, small restaurant, bakery 600–700 × 600 × 1,900mm (upright 1-door) 400–600L 60–100 covers Mid-sized restaurant, pub kitchen 700 × 700 × 2,000mm (upright 1-door) 700–1,000L 100–180 covers Full-service restaurant, hotel kitchen, club 1,200–1,400 × 700 × 2,000mm (upright 2-door) 1,000–1,400L 180–300+ covers High-volume restaurant, events kitchen, institutional 1,400 × 700 × 2,100mm (upright 2-door) Cover capacity is a guide only. It assumes a typical mix of ingredients — a predominantly fresh-fish restaurant will need 30–40% more refrigeration than an equivalent pasta-focused operation. Always audit your specific ingredient volumes when calculating. Space Planning Considerations Door Swing Clearance This is the most frequently overlooked dimension in kitchen planning. An upright fridge door opens to 90–115° depending on model. You need: Full door width as clearance in front of the unit for access Minimum 700–800mm from the fridge face to any opposite wall or equipment to comfortably load and unload shelves Check whether the door is reversible — most commercial fridges allow hinge reversal; specify at time of order for fitted kitchens Ventilation Clearance Air-cooled condensers need airflow to operate efficiently and maintain food safety temperatures: Sides: Minimum 100–150mm clearance from walls or adjacent equipment Rear: 100–150mm from the wall (rear-condensing models); some front-breathing models can be installed flush — check specifications Top: Where condenser is top-mounted, allow 200–300mm for heat dissipation Never install a refrigerator directly next to a heat source (oven, fryer, or high-heat cooking equipment) without a thermal barrier or significant separation. The compressor will overwork to compensate, dramatically shortening service life and increasing energy consumption. Floor Levelling Commercial refrigerators must be level for the door seal to function correctly and for the condensate drain to flow properly. Use the adjustable feet to level — most units provide 20–40mm of adjustment. Common Sizing Mistakes Sizing for today, not 18 months from now. If you're a new venue growing into your covers, size up by one tier. Retrofitting a larger fridge into a fitted kitchen mid-operation is expensive and disruptive. Comparing gross capacity across brands. A 600L fridge from Brand A may have significantly more usable shelf space than a 600L fridge from Brand B. Compare net capacity and shelf count. Ignoring door swing in the floor plan. Consistently one of the most common kitchen design errors — the fridge fits but the door can't open fully without hitting the bench opposite. Installing against cooking equipment without separation. Even a metre of separation between a fryer and a refrigerator makes a material difference to compressor load and service life. Forgetting condenser clearance. Blocking rear or side vents — even partially — will cause the unit to run at elevated temperatures, compromising food safety compliance and triggering premature compressor failure. What to Look for When Buying Temperature range: Confirm the unit maintains 0–5°C under full load in Australian ambient conditions (some cheaper units struggle above 30°C ambient). Look for units rated to 43°C ambient (Climatic Class 4/5). Energy efficiency: Refrigerators run 24/7. Check the annual energy consumption figure (kWh/year) in the spec sheet — this directly impacts running costs. Shelf load rating: Commercial shelves should be rated to at least 40–60kg per shelf. Verify if you're storing heavy containers. Door seal and gasket quality: Easy-to-replace magnetic door gaskets significantly reduce maintenance costs over time. Digital thermostat and alarm: Required for HACCP-compliant operations. Confirms the unit can maintain documented temperature logs. Local service support: Confirm service agents are available in your state for the brand you choose before committing.
