Pallet and Container Loading Calculator
How many pallets fit a container or trailer? Floor pattern, stacking tiers and payload are calculated together, and the calculator names which limit binds.

Worked example
Opened with its default case — Transport unit: 20' standard container — internal 5,898 × 2,352 × 2,393 mm · Pallet type: EUR / EPAL — 1,200 × 800 mm · Loaded pallet height (mm): 1500 — the calculator returns the figures below. The headline result is 11 pallets (loadable pallets). They are written out here so the output is readable without running JavaScript: in print, with scripts disabled, or by a search engine.
| Input | Value |
|---|---|
| Transport unit | 20' standard container — internal 5,898 × 2,352 × 2,393 mm |
| Pallet type | EUR / EPAL — 1,200 × 800 mm |
| Loaded pallet height (mm) | 1500 |
| Loaded pallet weight (kg) | 600 |
| Stacking | Not stackable — single tier |
| Result | Value |
|---|---|
| Pallets on the floor · pattern | 11 pallets · mixed pattern |
| Stacking tiers | 1 tier |
| Pallets by volume | 11 pallets |
| Pallets by payload | 47 pallets |
| Loadable pallets | 11 pallets |
| Binding constraint | Volume (floor pattern) |
| Floor utilisation | 76% |
| Payload utilisation | 23% |
| Total load | 6,600 / 28,200 kg |
| Unused floor area | 3.3 m² · 20' standard container |
Change any field above and the calculator recomputes; this table is the default case only.
How many pallets fit in a container?
The answer is not one number but the smaller of two limits: how many pallets fit by volume, and how many fit by payload. Light goods run out of space first; dense goods run out of tonnage first — and loading stops at whichever comes first. The floor pattern matters as much as the arithmetic: a 20' container takes 8 EUR pallets in a single orientation but 11 in a mixed pattern, because two 1,200 mm pallet edges side by side (2,400 mm) do not fit the 2,352 mm internal width. This calculator tries both and reports the better one.
Two limits, one answer
Every loading question has two independent ceilings and the load stops at the lower one:
| Limit | How it is calculated | What makes it binding |
|---|---|---|
| Volume | Pallets that fit on the floor × stacking tiers | Light, bulky goods — insulation, packaging, plastics, textiles |
| Payload | Payload capacity ÷ loaded pallet weight | Dense goods — fasteners, liquids, tools, tiles, metal stock |
A rough pre-check: above roughly 350–400 kg/m³ the payload runs out first; below that the volume does. This is why a container can look half empty and still be legally full.
The calculator shows both ceilings separately and names the binding one, because knowing which limit binds tells you what to change — repack for density, or split the consignment.
Why the floor pattern changes the number
This is where published “how many pallets fit” tables usually go wrong. A 20' container has an internal width of 2,352 mm. A EUR pallet is 1,200 × 800 mm. Two pallets placed side by side along their long edge need 2,400 mm — so they do not fit, and a naive single-orientation calculation returns 8 pallets.
In practice 11 are loaded. The difference is the mixed pattern: the floor is split into two strips, one loaded lengthwise and the other crosswise. The calculator runs a guillotine (single-cut) two-zone search in both directions and keeps the best result, so the figure it reports matches what a loading team actually achieves.
| Pattern | How the floor is used | Pallets on the floor |
|---|---|---|
| Single orientation | All pallets the same way round | 8 |
| Mixed pattern | One 800 mm strip lengthwise (4) + one 1,552 mm strip crosswise (7) | 11 |
The result is a geometric upper bound: no allowance is deducted for handling clearance, lashing or forklift access. Treat it as the ceiling a good loading plan approaches, not a guarantee.
Internal dimensions, not the name on the box
“20 foot” and “40 foot” describe the external length. Wall panels, corner castings and the floor structure all eat into the usable space: the internal length of a 20' standard container is 5,898 mm, roughly 200 mm shorter than the outside. Loading plans are always drawn on internal dimensions. ISO 668 and ISO 1496 define them.
| Unit | Internal L × W × H (mm) | Payload (kg) |
|---|---|---|
| 20' standard container | 5,898 × 2,352 × 2,393 | ≈ 28,200 |
| 40' standard container | 12,032 × 2,352 × 2,393 | ≈ 26,700 |
| 40' High Cube | 12,032 × 2,352 × 2,698 | ≈ 26,500 |
| Curtainsider trailer | 13,600 × 2,450 × 2,700 | ≈ 24,000 |
| 10-wheel rigid truck | 7,200 × 2,400 × 2,400 | ≈ 11,000 |
⚠ These are typical builder actuals, not ISO minima. ISO 668 specifies only a minimum internal size (5,867 × 2,330 × 2,350 mm for a 20') and no payload at all — it sets a maximum gross weight of 30,480 kg, and the payload on the CSC plate of the specific container governs. The trailer and rigid-truck rows follow no standard whatsoever; get the dimensions from your carrier in writing. Road weight limits at destination may also bite before the payload does.
Door openings: the limit people forget
A pallet planned against the internal height can still fail to pass the door. The ISO minimum door opening is 2,286 × 2,261 mm on a standard 20' or 40', and 2,286 × 2,566 mm on a High Cube — many containers are actually wider and taller (2,340 × 2,280 mm is common), but planning to the minimum is what keeps you safe. Check the loaded pallet against the door, not the roof. The calculator now runs this check itself and returns zero if the pallet cannot enter.
Calculate the pattern on the overhang, not the pallet. A load that projects 20 mm on each side of a 1,200 × 800 mm pallet actually occupies 1,240 × 840 mm — enough to lose a row across a container floor, and enough to weaken the stretch wrap at the corners.
Standard pallet sizes
| Pallet | Footprint (mm) | Where it is standard |
|---|---|---|
| EUR / EPAL | 1,200 × 800 | Europe, incl. Türkiye — the default |
| Industrial | 1,200 × 1,000 | Heavier goods, chemicals, drums |
| Half pallet | 800 × 600 | Retail display, small consignments |
ISO 3676 covers unit load dimensions. If your buyer’s warehouse runs a different footprint, say so at quotation stage — repalletising at destination costs more than getting it right at despatch.
Wood pallets on export shipments
On any shipment leaving Türkiye the pallet itself is regulated. Wood packaging falls under ISPM 15, which requires heat treatment and the IPPC mark; untreated wood can get an entire consignment refused at destination. Wood thinner than 6 mm and processed products such as plywood and particle board are outside the scope, which is why plywood and plastic pallets sidestep the question entirely.
The full picture — treatment parameters, what the mark must contain and where it must appear — is in our export shipping guide, together with the Incoterms and document sets that go with an export order.

Frequently Asked Questions
How many EUR pallets fit in a 20' container?
Eleven on the floor in a mixed pattern — four laid lengthwise in an 800 mm strip plus seven crosswise in the remaining 1,552 mm. A single-orientation layout gives only eight, which is why published tables disagree. Stacking and the container’s payload then decide the final number.
How many pallets fit on a trailer — 33 or 34?
Two layouts, two numbers, and that is where the confusion comes from. On a 13,600 × 2,450 mm curtainsider: turn the pallets crosswise (2 × 1,200 = 2,400 mm across) and 17 rows of 800 mm come to exactly 13,600 mm — 34 pallets, with literally zero slack. Turn them lengthwise (3 × 800 = 2,400 mm across) and 11 rows of 1,200 mm come to 13,200 mm, leaving 400 mm — 33 pallets. The trade figure is 33; the calculator’s 34 is the geometric ceiling with no handling clearance deducted. Industrial pallets give 26. All single-tier; where goods stack, the 2,700 mm internal height allows more and the practical ceiling is usually the 24-tonne payload.
How do I know whether volume or weight is the binding limit?
Work out both and take the smaller: pallets by volume = pallets on the floor × tiers; pallets by weight = payload ÷ loaded pallet weight. As a quick check, loads denser than roughly 350–400 kg/m³ run out of payload first, lighter ones run out of space.
Are these numbers a guarantee?
No. The result is a geometric upper bound calculated from internal dimensions: no allowance is deducted for handling clearance, lashing, dunnage or forklift access, and the CSC plate on the actual container governs its payload. Use it to plan and to sanity-check a forwarder’s figure, not as a loading certificate.
Do you handle the shipping as well as the goods?
We supply the materials and pack them for export. Carriage, insurance and customs clearance sit where the agreed Incoterms 2020 rule puts them, and the quote states line by line which is ours and which is yours.
