The Euronorm for crates (EN 4147) explained 

The Euro standard is a European sizing system for crates, based on the base dimensions of 600 x 400 mm. Crates of this size fit onto Euro pallets and block pallets without any wasted space. This ensures that storage and transport are seamlessly integrated throughout the entire supply chain. 

How the Euro Standard system works 

All Euronorm sizes are derived from the base dimensions of 600 x 400 mm. Smaller sizes fit into this space an exact number of times, whilst larger sizes are multiples of the base dimensions. 

This modular structure makes combining crates simple. Four 600 x 400 mm crates fill exactly one layer on a 1200 x 800 mm Euro pallet; five fit on a 1200 x 1000 mm block pallet. 

The table below shows the standard Euro-norm sizes and how they relate to the base size and the Euro pallet. 

Where does the designation EN 4147 come from? 

The term ‘EN 4147’ frequently appears in searches for the standard behind Euronorm crates. However, there is no official European standard with that number for crates. 

The number 4147 originates from the VDA-KLT system used by the German automotive industry. In this system, 4147 is a size code for a stacking bin measuring approximately 400 x 300 x 147 mm (RL-KLT 4147), not a standard number. 

In practice, the dimensions of Euronorm crates are based on the pallet standard EN 13698 and on product standards such as DIN 55423 for stackable crates. If in doubt, always request the specifications and test reports from your supplier. 

Why the logistics sector runs on the Euronorm 

Standardised dimensions mean that every link in the chain operates on the same basis. Pallets, roll containers, racking, washing systems and lorries are designed around the Euronorm base dimensions. 

This delivers immediate savings. Full pallet layers with no wasted space reduce transport costs per unit and shorten loading and unloading times. 

Automation also benefits. Conveyor belts, palletising robots and warehouse systems process standardised crates more quickly and with fewer malfunctions than non-standard sizes. 

Fixed base dimensions, flexible height 

The Euronorm specifies only the base dimensions. You are free to choose the height based on the product, its weight and the desired stacking height on the pallet. 

Common heights range from 75 to 420 mm. A low crate is suitable for heavy or fragile products; a tall crate makes better use of the pallet volume for light and bulky products. 

When making your choice, work backwards from the maximum stacking height. For example, a 1200 x 800 mm pallet with crates measuring 600 x 400 x 200 mm can accommodate nine layers within a loading height of two metres, including the pallet itself. 

Euronorm alongside other sizing systems 

In addition to the Euronorm, there are sector-specific systems. The automotive industry uses VDA-KLT bins, which are based on the same modular principle but employ their own base structures and codes. 

There are also variations in design within the Euronorm itself. Stackable crates sit firmly on top of one another, nestable crates slide into one another when empty, and twist-stackable crates combine both functions by rotating a quarter turn. 

Folding crates go one step further: when empty, they fold flat, reducing the return volume by more than three-quarters. For return logistics involving a lot of empty mileage, this is often the most cost-effective choice. 

What to look out for when choosing Euronorm crates 

Within the Euronorm dimensions, crates vary greatly in design. When making your choice, bear the following points in mind: 

• Stackability and load-bearing capacity determine how high you can safely stack crates during storage and transport. 

   

• Solid walls protect against moisture and dirt; perforated walls ensure air circulation for fresh produce. 

   

• Food-safe materials are required where there is direct contact with foodstuffs. 

   

• The temperature range is important for frozen storage or hot contents; high-quality crates operate from minus 18 to plus 40 degrees Celsius. 

   

• Label integration via barcode or RFID makes every crate traceable throughout the supply chain. 

A good Euronorm crate will last well over fifteen years under normal use. The purchase price is therefore less important than the cost per cycle.
