Knowing how many pallets can fit inside a shipping container is one of the most common questions in logistics—and a key factor for planning costs, preparing cargo and optimizing load efficiency. The answer depends on three main variables: container size (20 ft or 40 ft), pallet type (EUR or US standard), and the chosen loading layout.
This guide provides a clear and practical breakdown of pallet capacity for both 20ft and 40ft containers, including diagrams, real measurements, layout techniques and best practices to ensure a safe and efficient load.
20ft vs 40ft containers: internal dimensions
The number of pallets that can fit inside a container depends directly on its internal measurements, not the external ISO dimensions.
Below are the standard internal dimensions used globally:
📌 20ft Standard Container (20’ DV)
- Internal length: ~5.90 m
- Internal width: ~2.35 m
- Internal height: ~2.39 m
- Volume: ~33 m³
📌 40ft Standard Container (40’ DV)
- Internal length: ~12.03 m
- Internal width: ~2.35 m
- Internal height: ~2.39 m
- Volume: ~67 m³
📌 40ft High Cube Container (40’ HC)
Same width and length as a 40 ft standard, but with extra height:
- Internal height: ~2.70 m
- Volume: ~76 m³
Height does not affect pallet count directly, but helps with tall cargo.
Pallet standards used in global shipping
There are two main pallet standards used for international cargo:
✔ EUR Pallet (European Pallet – EUR / EPAL)
- Dimensions: 1200 × 800 mm
- Common in Europe, Middle East, Africa.
✔ US Pallet (ISO / North American Pallet)
- Dimensions: 1219 × 1016 mm
- Common in the Americas and Asia-Pacific.
How many pallets fit in a 20ft container?
Because of the shorter length, a 20ft container accommodates fewer pallets and offers only one main layout option.
A) EUR Pallets in a 20ft container
- ➡ Capacity: 11 EUR pallets
This is globally recognized as the standard maximum.
Layout (top-down view):
| 5 | 6 | | pallets |
Total: 11
Distribution:
- 5 pallets lengthwise
- 6 pallets arranged using a mixed orientation
B) US Pallets in a 20ft container
- ➡ Capacity: 9–10 pallets
The standard capacity is:
- 10 pallets using mixed orientation
- 9 pallets using uniform orientation
Layout:
| 4 + 5 pallets | or | 9 aligned pallets |
The width and corners limit capacity beyond 10.
How many pallets fit in a 40ft container?
A 40ft container offers significantly more space and multiple layout possibilities.
A) EUR Pallets in a 40ft container
- ➡ Capacity: 25 EUR pallets
This is the globally accepted maximum, using optimized layout.
Layout:
| 11 pallets | 14 pallets |
Total: 25 EUR pallets
Achieved via alternating vertical/horizontal pallets, using a tight-fit method.
B) US Pallets in a 40ft container
- ➡ Capacity: 20 US pallets
This is due to their larger dimensions.
Layout:
| 10 pallets | 10 pallets |
Total: 20
Simple, symmetrical loading.
C) Mixed/irregular pallets
When pallets vary in size or have irregular overhang, real capacity may drop to:
- 18–24 pallets depending on configuration.
Visual pallet capacity summary
20ft Container
| Pallet Type | Capacity |
| EUR (120 × 80 cm) | 11 pallets |
| US (121.9 × 101.6 cm) | 9–10 pallets |
40ft Container
| Pallet Type | Capacity |
| EUR (120 × 80 cm) | 25 pallets |
| US (121.9 × 101.6 cm) | 20 pallets |
Best loading practices to maximize pallet capacity
Loading pallets efficiently is not only about quantity—safety, stability and compliance matter as well. Here are best practices used by freight forwarders and warehouse teams worldwide.
A) Alternate pallet orientation
This helps maximize space without damaging boxes or creating pressure points.
Orientation examples:
- Long side–long side
- Long side–short side
- Brick pattern for mixed cargo
B) Avoid overhang
Overhanging boxes reduce the pallet count and increase the risk of:
- Box crushing
- Shifting
- Damage during transport
Make sure boxes stay within pallet edges.
C) Check weight distribution
Containers must be loaded:
- Heavier pallets at the front (near the nose)
- Balanced left/right
- Evenly distributed across the length
Improper balance increases risks during:
- Crane lifting
- Vessel stowage
- Road transport braking
D) Use proper securing equipment
A safe load requires:
- Lashing straps
- Dunnage bags
- Anti-slip mats
- Blocking and bracing material
- Corner protectors
This prevents shifting under sea movement.
E) Consider pallet height
Standard internal container heights:
- 20ft/40ft DV: 239 cm
- 40ft HC: 270 cm
When palletized cargo exceeds these heights, capacity changes.
Examples:
- 2-tier stacking may be possible inside a 40ft HC if pallet height < 135 cm
- Certain European FMCG loads are pre-stacked to 180–220 cm
Volume vs pallet count: which one matters more?
Many shippers think pallet count is the most important metric, but in reality, density can be equally limiting. Examples:
Low-density cargo (e.g., paper towels, textiles)
- You may fill the container by volume before reaching pallet limit.
High-density cargo (e.g., liquids, tiles, canned goods)
- You may reach MAXIMUM WEIGHT before all pallets fit.
Weight limits:
- 20ft container max payload: ~28,000 kg
- 40ft container max payload: ~28,500 kg
Even though the 40ft has more space, its weight capacity is nearly the same as a 20ft.

Frequently asked questions
Yes—taller pallets may limit stacking and affect total load height.
Yes, but capacity usually drops.
No, pallet count is limited by floor dimensions, not height.
Depends on cargo; mixed orientation maximizes space but requires careful securing.
A 20ft container fits 11 EUR pallets or 9–10 US pallets, while a 40ft container fits 25 EUR pallets or 20 US pallets. The exact configuration depends on pallet type, orientation, height, and whether the cargo is dense or volumetric.
By understanding dimensions, layouts and best loading practices, shippers can optimize space, reduce transport costs and ensure safe, stable loads during international movement.
