Introduction
A 20 ft container holds 9 standard 48" × 40" pallets on the floor, and a 40 ft container holds 20. Those two numbers shape freight cost, loading time and how much cargo you can move per shipment.
Many guides round the 20 ft figure up to 10. The container's inside width makes that tight, so planning for 9 avoids surprises at the warehouse. This post explains the layouts, the basics of pallets, and why palletized loading pays off.
What is a standard pallet?
A pallet is a flat platform made of wood, steel, plastic or fiber that carries goods through storage and transport. Forklifts and hand pallet trucks move it in and out of containers.
Attribute | Standard 48" × 40" pallet |
|---|---|
Length × width | 48 × 40 in (1,219 × 1,016 mm) |
Height | 5 to 6.5 in |
Typical load capacity | 1,000 kg or more (confirm with the manufacturer) |
Handling equipment | Forklift, hand pallet truck |
Export requirement | Wooden pallets need fumigation and a certificate in most countries |
The 48" × 40" size is the most widely used pallet, especially in North America.
20 ft container: 9 pallets
A 20 ft container measures about 5.90 m long and 2.35 m wide inside. That width decides the layout.
- Two pallets fit side by side only with their 40" sides across the width (2 × 1.016 m = 2.03 m).
- Each pair uses 1.219 m of length, so four pairs take 4.88 m.
- The remaining 1.02 m fits one more pallet turned sideways.
That gives 4 × 2 + 1 = 9 pallets. Two pallets turned the other way need 2.44 m of width, which the container does not have, so a 10th pallet will not fit reliably.
40 ft container: 20 pallets
A 40 ft container is about 12.03 m long and the same 2.35 m wide. The best layout runs two lanes with mixed orientation.
Lane | Pallet orientation | Lane width | Pallets |
|---|---|---|---|
Lane 1 | 48" along the length | 1.016 m | 9 |
Lane 2 | 40" along the length | 1.219 m | 11 |
Total | 2.235 m | 20 |
Both lanes together use 2.235 m of the 2.35 m width, leaving a small gap for dunnage or airbags.
Benefits of palletized shipping
- Operational efficiency: Forklift loading and unloading is much faster than manual stuffing and de-stuffing. It also cuts reliance on headload workers.
- Better use of space: Pallets can be stacked, using the container's vertical space. Double stacking roughly doubles capacity to about 18 pallets (20 ft) and 40 pallets (40 ft), if the cargo can bear the weight.
- Less damage: Goods secured with lashing and shrink-wrap move as one unit. That reduces damage during stuffing, de-stuffing and transit.
Key takeaways
- A 20 ft container fits 9 standard 48" × 40" pallets in a single tier; plan on 9, not 10.
- A 40 ft container fits 20 pallets using two lanes with mixed orientation.
- Double stacking can roughly double these counts if cargo strength and weight limits allow.
- Payload limits (about 28 t for a 20 ft) often cap heavy cargo before floor space does.
- Wooden pallets usually need fumigation and a certificate for export and import.
- Palletizing speeds loading, saves space and reduces cargo damage.
Frequently Asked Questions
Q1: How many 48" × 40" pallets fit in a 20 ft container?
Nine in a single tier. Some sources say 10, but the 2.35 m inside width makes a 10th pallet impractical.
Q2: How many fit in a 40 ft container?
Twenty in a single tier, using one lane of 9 and one lane of 11 pallets.
Q3: Does a 40 ft high cube container hold more pallets?
Not on the floor; it has the same length and width. Its extra height (about 30 cm) makes double stacking easier.
Q4: How many Euro pallets (1200 × 800 mm) fit?
About 11 in a 20 ft container and 23 to 24 in a 40 ft container.
Q5: Can pallets be double stacked?
Yes, if the goods and pallets can bear the load and the total stays within the container's payload limit.
Q6: Do wooden pallets need treatment for export?
Yes, most countries require heat treatment or fumigation under the ISPM 15 standard, with a certificate or stamp.
Q7: How do I stop pallets moving inside the container?
Fill leftover gaps with airbags or dunnage and secure loads with lashing and shrink-wrap.
