Calculator 09 / Cargo & Load Space
Cargo & Load Space Calculator
How many pallets fit depends on their orientation, not just the floor area — turning them ninety degrees often changes the count. Get cargo volume and how many pallets fit in a truck bed, box, or trailer based on interior dimensions.
How this calculator works
Units below default automatically — Metric for non-English pages (or if your device's language is set to one we support), US customary otherwise — and convert automatically if you switch the toggle above the form. Changing language resets to that language's default unless you toggle again.
The calculator checks both possible pallet orientations (lengthwise and rotated 90°) and uses whichever fits more pallets per layer — this is the same "pallet pattern" logic freight planners use before booking a load. It assumes pallets are loaded in a simple grid with no angled or interlocking patterns, which is a conservative (safe) estimate — a skilled loader may fit slightly more with a mixed pattern.
Worked example: a 26-foot box truck
The defaults are a 26 ft × 8 ft × 8.5 ft box, GMA pallets at 48 × 40 in, stacked 48 in high:
- Interior in inches = 312 × 96 × 102
- Pallets 48 in along the length: (312 ÷ 48) × (96 ÷ 40) = 6 × 2 = 12
- Pallets turned 90°: (312 ÷ 40) × (96 ÷ 48) = 7 × 2 = 14
- Better orientation wins = 14 per layer
- Layers = 102 ÷ 48 = 2 high
- Total = 14 × 2 = 28 pallets, in 1,768 ft³
Turning the pallets is worth two extra per layer here — about 17% more floor positions from nothing but orientation. That is the single biggest lever in this calculation, and it is why the tool tests both ways round rather than assuming one.
Floor positions in common equipment
Every row is this calculator's own output for GMA 48 × 40 in pallets, so you can reproduce any of them by typing the dimensions in. Interior dimensions vary between makes and model years — measure yours rather than trusting a category.
| Equipment | Interior used | Straight | Turned | Best |
|---|---|---|---|---|
| 53 ft dry van | 53 × 8.5 ft | 26 | 30 | 30 |
| 48 ft dry van | 48 × 8.33 ft | 24 | 28 | 28 |
| 28 ft pup | 28 × 8.33 ft | 14 | 16 | 16 |
| 26 ft box truck | 26 × 8 ft | 12 | 14 | 14 |
| 40 ft container | 39.5 × 7.7 ft | 18 | 11 | 18 |
| 20 ft container | 19.4 × 7.7 ft | 8 | 5 | 8 |
The 53 ft row is the standard sanity check: 26 pallets loaded straight, 30 turned are the figures the industry quotes, and the model reproduces both. Containers are the opposite case — they are narrow enough that turning the pallets makes things worse, which is why their straight and turned columns are so far apart.
Standard pallet footprints
| Pallet | Metric | Inches | Where you meet it |
|---|---|---|---|
| GMA / North American | 1219 × 1016 mm | 48 × 40 in | The default across US grocery and general freight |
| Square | 1219 × 1219 mm | 48 × 48 in | Drums, chemicals, some industrial freight |
| Euro EUR1 | 1200 × 800 mm | 47.24 × 31.5 in | The European standard; the calculator's third preset |
| Euro EUR2 / industrial | 1200 × 1000 mm | 47.24 × 39.37 in | Heavier European freight — enter as custom |
| Asia / ISO | 1100 × 1100 mm | 43.31 × 43.31 in | Common across Asian trade lanes — enter as custom |
A EUR1 pallet is narrower than a GMA one and taller in its long dimension, so a space that suits one often wastes room with the other. If your freight arrives on pallets you did not choose, measure them — "Euro pallet" covers several sizes and the calculator's preset is only the most common.
You will usually run out of weight first
This calculator counts space and nothing else. On a tractor-trailer at the 80,000 lb federal gross limit, payload is roughly 42,000–47,000 lb once the tractor and trailer tare is deducted — so on all but the lightest freight, the weight limit binds long before the cube does. Below, a 53 ft van that holds 30 pallets by space, against a 45,000 lb payload.
| Weight per pallet | 30 pallets weigh | Pallets by weight | What binds |
|---|---|---|---|
| 800 lb | 24,000 lb | 56 | Space — a true "cube-out" load |
| 1,000 lb | 30,000 lb | 45 | Space |
| 1,200 lb | 36,000 lb | 37 | Space, with little margin |
| 1,500 lb | 45,000 lb | 30 | Both at once — the balance point |
| 1,800 lb | 54,000 lb | 25 | Weight — 5 floor positions go empty |
| 2,200 lb | 66,000 lb | 20 | Weight — a third of the trailer stays empty |
Around 1,500 lb per pallet the two limits meet. Below it you are shipping air and should be looking at cube; above it, floor positions stop being the constraint entirely and the question becomes where the weight sits, not whether it fits. Gross weight is also only one of the limits — single-axle, tandem-axle and Bridge Formula limits apply at the same time, and state limits differ.
Where this goes wrong
- It only tries two uniform orientations. Real loaders mix orientations and pinwheel the last row, which can gain positions this model does not see — the 40 ft container above is a case where hand-loading beats the calculation. Treat the answer as a floor, not a ceiling.
- Using exterior dimensions. Wall thickness, liner and posts cost several inches each way, and a few inches decides whether another row fits. Measure inside.
- Ignoring overhang. Freight stacked wider than its pallet does not occupy a 48 × 40 in footprint any more, and the count silently becomes wrong.
- Forgetting what else is in the box. Load bars, dunnage, airbags, a reefer unit's bulkhead and the wheel wells on a box truck all take space this calculation gives you.
- Assuming everything is stackable. The layer count is pure arithmetic on the height you enter. Crushable freight, mixed pallet heights and "do not double stack" labels are all invisible to it.
- Treating a fit as a legal load. Securement under 49 CFR 393 subpart I, weight distribution across the axles, and the load's own centre of gravity are separate questions, and none of them are answered by whether the pallets fit.
Where these numbers come from
Volume tells you whether a load fits. It does not tell you whether it is legal or secured, and those are decided elsewhere.
- 49 CFR 393.102 — Cargo securement performance — Minimum performance criteria for tiedowns, and the forces a load must be restrained against.
- 49 CFR Part 393 — Parts and Accessories — Subpart I holds the full cargo-securement rules, including the commodity-specific ones.
Does this account for weight limits?
No — this is a space/volume calculator only. Check your Towing & Payload numbers separately to make sure the cargo weight stays within your vehicle's rating even if it physically fits.
Why would real-world pallet count be different?
Door swing clearance, load bars, uneven pallet sizes, and non-stackable freight can all reduce usable space below the theoretical grid maximum calculated here.
Estimates only. Always confirm actual load space against your specific trailer or truck body's real interior dimensions, which can vary from nominal/advertised sizes.
