A 40-foot container's floor is 28.3 m². A Euro pallet's footprint is 0.96 m². The math says 29 pallets. The field says 25. Most operations stop at 20–21 — and cover the gap by booking a second container.
The short answer: a 20ft container takes 11 Euro pallets (800 × 1,200 mm) or 10 industrial pallets (1,000 × 1,200 mm) in a single tier; a 40ft and a 40ft high cube take 25 Euro pallets, 21 industrial, or 20–21 GMA 48 × 40s. If you can double-stack, those numbers double on paper; in practice the weight limit usually fills before the space does.
What separates 20–21 from 25 isn't the container's dimensions — it's which way the pallets face. Every number below was verified, pallet by pallet, in real load plans.
Quick Answer: Pallet Capacity by Container Type
| Container | Internal floor (L × W) | Euro pallets (800 × 1,200) | Industrial (1,000 × 1,200) | Double-stacked Euro* |
|---|---|---|---|---|
| 20' DC | 5.90 × 2.35 m | 11 | 10 | 22 |
| 40' DC | 12.03 × 2.35 m | 25 | 21 | 50 |
| 40' HC | 12.03 × 2.35 m | 25 | 21 | 50 (more comfortably) |
| 45' HC | 13.58 × 2.35 m | 27 | 24 | 54 |
Why do a 40' DC and a 40' HC take the same number of pallets? Because their floors are identical: 12.03 × 2.35 m. The high cube's only difference is ~31 cm of extra internal height — which buys you a more comfortable second tier, not more floor positions. Full internal dimensions and the volume math are in our CBM calculation guide.
Pallet Standard Changes Everything
"Pallet" is not one thing. Most palletized freight moving through Europe rides the Euro pallet (EPAL); the US runs on the GMA 48 × 40 in pallet — the everyday "skid"; and deep-sea lanes will show you at least two more standards. The answer to "how many pallets fit in a container?" changes with every one of them.
| Pallet type | Footprint (mm) | In a 20ft | In a 40ft | Where you'll meet it |
|---|---|---|---|---|
| Euro pallet (EPAL 1) | 800 × 1,200 | 11 | 25 | Europe, UK retail, most deep-sea FCL |
| GMA pallet (48 × 40 in) | 1,016 × 1,219 | 9–10 | 20–21 | US domestic freight — sits awkwardly in ISO boxes |
| Industrial pallet (EPAL 2) | 1,000 × 1,200 | 10 | 21 | Chemicals, appliances, heavy industry |
| Asia pallet | 1,100 × 1,100 | 10 | 20 | Japan and Far East lanes |
| Half pallet (EPAL 6) | 800 × 600 | 21 | 45 | Retail, e-commerce |
The differences look small on paper and hit hard inside the box. The GMA 48 × 40 was shaped around US truck trailers, not ISO containers: two 48 in sides need 2,438 mm across a floor that offers 2,352 mm, so the layout locks and a 40ft takes only 20–21 of them against 25 Euro pallets. Re-palletizing a Europe-bound product from GMA to Euro is worth up to 25% more capacity per container — and even Euro versus industrial is a 4-pallet, 16% swing.
How Many Pallets Fit in a 20ft Container? The Math Behind 11
Let's open up the math. A 20' DC's internal floor is 5.90 × 2.35 m = 13.84 m². A Euro pallet's footprint is 0.96 m². Division says "14.4 pallets". The real answer is 11 — pallets don't split, and edges don't land flush. The count depends on the layout you choose:
5.90 ÷ 1.20 = 4 rows × 2 across = 8 pallets 1.10 m of dead floor left at the door end
5.90 ÷ 0.80 = 7 rows × 1 across = 7 pallets a 1.15 m strip runs empty along the width
120 cm lane: 7 pallets on their 80 cm side remaining 115 cm lane: 4 pallets on their 120 cm side 7 + 4 = 11 pallets
Same container, same pallet; three layouts, three answers: 7, 8, or 11. Worst to best is a 57% spread. The image below is Layout C as real CargoDuo output:
A 40ft Container: 20 Pallets in One Orientation, 25 in Two
A 40' DC's internal floor is 12.03 × 2.35 m. Line every pallet up the same way, 120 cm side along the length, and you get 10 rows × 2 across = 20 pallets, with a 75 cm strip wasted along the wall. Pinwheeling splits the floor into two lanes instead: 15 pallets on their 80 cm side in a 120 cm-wide lane, plus 10 pallets on their 120 cm side in the remaining 115 cm lane — 25 in total. This is where the question from the intro gets answered: the entire difference between an operation stuck at 20–21 and one loading 25 is turning part of the pallets 90°. Those 4–5 pallets are, on an average shipment, the difference between booking one container and booking two.
When does the 40ft high cube pay off?
The HC's ~2.70 m internal height allows double-stacking for pallet loads up to about 1.30 m; in a standard 40' DC (2.39 m) the same limit is ~1.15 m. In other words, the high cube doesn't buy you floor — it buys you the second tier:
| Pallet-load height (pallet included) | Double-stack in a 40' DC (2.39 m) | Double-stack in a 40' HC (2.70 m) |
|---|---|---|
| 1.00 m | Yes | Yes |
| 1.15 m | Borderline (9 cm to spare) | Yes |
| 1.30 m | No | Yes |
| 1.60 m | No | No |
In Double-Stacking, the Binding Limit Is Weight, Not Volume
Before doubling the pallet count, run this check: the payload on the container's equipment sheet sits at around 28 tonnes, but the road leg cuts real loading off at ~26,000 kg on UK/EU combinations — and even earlier in the US (details below). Divide that ceiling by the pallet count and the table gets blunt:
| Scenario | Pallet count | Max weight per pallet* |
|---|---|---|
| 40ft — single tier | 25 | ~1,040 kg |
| 40ft — double-stacked | 50 | ~520 kg |
| 20ft — single tier | 11 | ~2,360 kg |
| 20ft — double-stacked | 22 | ~1,180 kg |
Real Scenario: 25 Pallets of Flat-Pack Furniture, Shanghai to Rotterdam
A furniture maker outside Shanghai is loading flat-pack wardrobes for a distributor in Rotterdam: 25 Euro pallets, load height 1.55 m including the pallet, 380 kg gross each — 9,500 kg all in. The planner works off the "a 40ft takes 21 pallets" rule of thumb and books 1 × 40' DC + 1 × 20' DC.
The right plan falls out of two quick checks. One: a 1.55 m pallet load can never double-stack in any dry box (2 × 1.55 = 3.10 m against at most 2.70 m of headroom). Two: it doesn't need to — pinwheeled, all 25 pallets sit on the floor of a single 40' DC. The hero image at the top of this article is that exact shipment. Weight check: 9,500 kg, nowhere near the ~26 t ceiling.
| Plan A: the "40ft takes 21" rule of thumb | Plan B: the pinwheeled load plan | |
|---|---|---|
| Equipment | 1 × 40' DC + 1 × 20' DC | 1 × 40' DC |
| Floor plan | 21 + 4 pallets, the 20ft half empty | all 25 pallets in one container |
| Freight (Drewry WCI, 6 August 2026) | ~$7,100 | ~$4,297 |
| Customs and port paperwork | 2 sets | 1 set |
| Difference | — | ~$2,800 + one set of paperwork |
The difference isn't in the container and it isn't in the pallets. It's in the load plan.
The 5 Most Common Pallet-Loading Mistakes
- Treating single-orientation loading as the default. Lining every pallet up the same way costs 4–5 pallet positions in a 40ft; the pinwheeled layout should be the standard, not the exception.
- Not measuring pallet overhang. The 800 × 1,200 on the label can be 850 × 1,250 once wrapped — and a full pallet position disappears along the length.
- Ignoring weight distribution. Bunching heavy pallets at one end unbalances the container; on the road leg it comes back as an axle overload at the weighbridge.
- Not planning the door zone and unloading order. The pallets nearest the door come off first; get the order wrong on a multi-stop load and the first stop means restowing the entire container.
- Double-stacking without checking crush strength. If the bottom cartons crush, the damage claim costs more than the space you saved.
The pre-loading checklist
- Was the pallet's true outer footprint, stretch wrap included, measured?
- Pallet-load height ÷ internal height — how many tiers?
- Is the total weight under the road-legal ceiling (~26 t UK/EU, ~19–20 t US)?
- Double-stacking: is the per-pallet weight under the threshold?
- Was a pinwheeled (mixed-orientation) layout tried?
- Does the unloading order match the stop sequence?
Don't Forget the Road Leg
The pallets you fit into the box still have to reach the port on a truck. In the UK, a 6-axle articulated combination carrying an ISO container runs at a 44-tonne maximum gross under the Road Vehicles (Authorised Weight) Regulations 1998; subtract the tractor and skeletal trailer (~12–13 t combined) and the 40ft box's ~3.8 t tare, and roughly 26–27 t is left for cargo. EU intermodal legs under Directive 96/53/EC land in the same place — which is where this article's ~26,000 kg convention comes from. On a US road leg the ceiling drops hard: the 80,000 lb (36,287 kg) federal gross limit plus the bridge formula leaves roughly 19–20 t of cargo in a 40ft on a standard chassis, state overweight permits aside; Singapore hauliers work to LTA rules that cap laden trailer weights in the same spirit. Note the gap against the box's own rating — a 40ft can legally hold ~26,700 kg at 30,480 kg max gross, more than most roads let you drive. And a layout that bunches weight at one end may cross the ocean untouched, then earn you an axle-overload fine at the weighbridge; the load plan has to spread weight along the full length.

Conclusion: The Number Isn't Fixed — the Plan Is the Variable
"How many pallets fit in a container" has no single right answer; it depends on your pallet standard, your load height, your tonnage, and most of all your floor plan. The same 40ft container takes 20 pallets or 25 with the very same pallets — and those 5 pallets compound into dozens of containers a year.
Frequently Asked Questions
How many pallets fit in a 40ft container?
25 Euro pallets (800 × 1,200 mm) in a single tier — but only with a pinwheeled floor plan; a single-orientation layout stops at 20. Industrial pallets (1,000 × 1,200 mm) come to 21, and GMA 48 × 40 in pallets to 20–21. A 40ft high cube takes exactly the same floor counts. Double-stacking doubles the numbers in theory, but road-leg weight limits usually bind first.
How many Euro pallets fit in a 20ft container?
11 in a single tier: a 120 cm-wide lane takes 7 pallets on their 80 cm side, and the remaining 115 cm lane takes 4 on their 120 cm side. Industrial pallets come to 10. If the pallet load is under about 1.15 m and the weight allows it, double-stacking can lift a 20ft to 22.
Can you double-stack pallets in a shipping container?
Yes — when three conditions hold at once: twice the pallet-load height fits the internal height (up to ~1.15 m per tier in a 40' DC, ~1.30 m in a 40' HC); total weight stays under the road ceiling — 50 pallets in a 40ft leaves only ~520 kg per pallet; and the bottom tier's goods can carry the top tier without crushing (check the ISO 780 stacking mark on the cartons). In practice, weight and crush strength say no long before the geometry does.
How many pallets fit in a 40ft high cube container?
The same as a standard 40ft: 25 Euro or 21 industrial pallets, because the floors are identical at 12.03 × 2.35 m. The high cube's ~31 cm of extra internal height doesn't add floor positions — it makes double-stacking realistic, taking pallet loads up to ~1.30 m per tier where the standard box stops at ~1.15 m.
Do 48x40 (GMA) pallets fit in a shipping container?
They fit, but inefficiently. The GMA pallet (1,016 × 1,219 mm) was shaped around US 53-foot trailers, not ISO boxes: two 48 in sides need 2,438 mm across a floor that is 2,352 mm wide, so the layout locks up and a 40ft takes only 20–21 GMA pallets against 25 Euro; a 20ft takes 9–10. For Europe-bound freight, re-palletizing onto Euro pallets often pays for itself in container count alone.
What is pinwheeling pallets, and how does it get you to 25?
Pinwheeling (mixed orientation) splits the container floor into lanes with the pallets turned 90° to each other. In a 40ft: a 120 cm-wide lane takes 15 Euro pallets on their 80 cm side, and the remaining 115 cm lane takes 10 on their 120 cm side — 25 in total, against 20 for an all-one-way layout. We verified the 25-pallet layout with a real load plan; it's the hero image of this article.
How much weight can a 40ft container carry on the road?
The box itself is rated for ~26,700 kg of payload at 30,480 kg max gross — but the road leg binds first. A UK or EU container combination is limited to 44 tonnes gross, which leaves roughly 26,000 kg for cargo after the tractor, chassis, and container tare. On US roads, the 80,000 lb federal gross limit leaves roughly 19–20 t in a 40ft on a standard chassis. Plan to the road-leg number, not the container's rating.
Is it cheaper to floor-load cartons than to ship on pallets?
Per cubic meter of freight, usually yes: floor-loading recovers the pallet's own ~14.4 cm of height plus its footprint losses, and often fits 10–15% more cartons in the same box. But the saving moves to the other side of the ledger — loading and unloading by hand takes hours instead of minutes, damage rates climb, and every touch needs labor instead of a forklift. Floor-loading tends to win for light, uniform cartons on long ocean lanes; palletized freight wins wherever handling speed, damage risk, and warehouse flow matter more.
Container internal dimensions are from ISO 668 and carrier equipment sheets (Maersk, Hapag-Lloyd, MSC); Euro pallet dimensions and load ratings from the EPAL standard; the carton stacking mark from ISO 780; road weight limits from the UK Road Vehicles (Authorised Weight) Regulations 1998, EU Directive 96/53/EC, and the US 80,000 lb federal gross limit with the bridge formula. The 25 / 11 / 50-pallet layouts and fill rates in this article are the output of real load plans run in CargoDuo.
