How many pallets fit in a truck? 33… or 34 — here's the proof

Updated

Short answer: a standard 13.6 m European semi-trailer takes 33 Euro pallets on the floor with the classic 3-wide pattern… and 34 with a pattern most industry tables never mention. Never 35 — and we'll prove that geometrically.

This guide gives floor counts (single-stacked) for each vehicle type, based on the interior dimensions of ALPHA LOADING's presets (trailer: 13,600 × 2,450 mm). It also shows the working — because a number without proof is just an opinion.

The classic pattern: 33 pallets, 3-wide

A Euro pallet measures 1,200 × 800 mm. Loaded lengthwise (1,200 mm along the trailer), three fit side by side: 3 × 800 = 2,400 mm, within the 2,450 mm interior width. Along the length: 13,600 / 1,200 = 11 rows (13,200 mm). 11 × 3 = 33 pallets, with 400 mm of floor wasted at the back.

This is the pattern everyone knows — the one in loading tables and FTL rate cards. It's simple, fast to load, and it leaves one pallet on the dock.

The true optimum: 34 pallets, turned sideways

Rotate every pallet 90°: 800 mm along the trailer, 1,200 mm across. Widthwise: 2 × 1,200 = 2,400 mm ≤ 2,450 mm. Lengthwise: 13,600 / 800 = exactly 17 rows — not a millimetre wasted. 17 × 2 = 34 pallets.

Why do industry tables say 33? Because they only consider the 3-wide pattern. The sideways pattern uses 34 × 0.96 = 32.64 m² of the 33.32 m² floor — 98% versus 95% for 3-wide. The 34th pallet isn't a software gimmick: it's geometry that a spreadsheet never goes looking for.

And never 35. The proof is one division: the floor offers 13.6 × 2.45 = 33.32 m²; a Euro pallet occupies 0.96 m²; 33.32 / 0.96 = 34.7. Even if you could slice pallets — which physics forbids — 35 don't fit. Any tool claiming 35 Euro pallets on the floor of a 13.6 m trailer is inventing space. Change tools.

Industrial 1200 × 1000 pallets: 26 on the floor

For the 1,200 × 1,000 mm industrial pallet (EPAL 2 / EPAL 3), the width only allows 2 pallets abreast (2 × 1,200 = 2,400 mm; 3 × 1,000 = 3,000 mm won't go). With the 1,000 mm side along the trailer: 13,600 / 1,000 = 13 rows. 13 × 2 = 26 pallets. This is the decisive factor in pallet choice: the 1200 × 800 goes 3-wide where the 1200 × 1000 only goes 2-wide.

Euro pallets (1200 × 800) on the floor, by vehicle typeALPHA LOADING presets, pallets on the floor, no overhang. Note the 13.3 m reefer: the sideways pattern only yields 16 rows × 2 = 32 — the 34-pallet layout needs the full 13.6 m (17 × 0.80 m). Turning pallets there LOSES a slot.

The trap: weight maxes out before floor space

34 slots don't mean 34 full pallets. A standard trailer carries about 24,000 kg of payload: across 34 pallets, that's 705 kg per pallet maximum — while a Euro pallet is rated up to 1,500 kg dynamic load. For dense freight (beverages, tiles, paper), weight saturates long before the floor does: 24 t / 1,500 kg = just 16 fully-laden pallets.

Then come axle loads: a load within the gross weight limit can still fail the weighbridge because heavy pallets are bunched at the front or rear. That's a distribution problem — one that only a full load plan checks.

Finally, double-stacking changes everything when the goods allow it: 33 floor pallets become 66 double-stacked — if the height (2,700 mm in a standard trailer, 3,000 mm in a mega) and the strength of the bottom pallets permit.

Frequently asked questions

How many Euro pallets fit in a 13.6 m trailer?
33 on the floor with the classic 3-wide pattern (11 rows × 3), and 34 with the sideways pattern (17 rows × 2, pallets rotated 90°). 34 is the absolute geometric maximum: the area bound is 33.32 / 0.96 = 34.7.
Why does my haulier only count 33 pallets?
Industry loading tables only consider the 3-wide pattern. The sideways pattern needs the full 13.6 m and more careful side loading — but it's perfectly legal and fits the width (2 × 1,200 = 2,400 mm ≤ 2,450 mm).
How many pallets fit in a rigid truck?
On our presets: about 18 Euro pallets in a 12-tonne rigid (7.2 m floor) and 20 in a 19-tonne rigid (8.0 m, sideways pattern). Watch the payload: 5,800 kg on a 12-tonner is barely 320 kg per pallet at full floor.
Can you fit 35 Euro pallets in a trailer?
No. A 13.6 m trailer floor offers 33.32 m² and 35 pallets would need 33.60 m². Any software or table claiming 35 on the floor is wrong — or is quietly talking about double-stacking or a longer combination vehicle.
Does the maths change for a refrigerated trailer?
Yes: insulation shortens the body (13.3 m on our preset). It takes 33 Euro pallets 3-wide, but the sideways pattern caps at 32 — the 34-pallet layout strictly requires a 13.6 m floor.
