How many 400 × 300 × 300 mm boxes fit on a UK pallet?
400 × 300 × 300 mm boxes of 400 × 300 × 300 mm (also called 40 × 30 × 30 cm cartons, quarter-Euro cartons) on a UK / industrial pallet 1200 × 1000 mm (stacked to 1.8 m) — deck 1,200 × 1,000 mm, cargo up to 1,656 mm high. Calculated by the Cubestow engine on 2026-09-08.
Boxes may be laid on any side. 94% of the space used, 7 layers high, about 312 kg (31% of payload). Open this load in the 3D planner →

The answer in detail
The 400 × 300 footprint is a quarter of a EUR pallet deck (eight per layer), which makes it a favourite e-commerce shipping carton.
The 1,200 × 1,000 mm "industrial" or UK standard pallet, stacked to 1,800 mm including the 144 mm pallet (1,656 mm of cargo). No overhang.
The simple grid estimate is 3 along the length × 3 across × 7 high = 63. The engine found 52 — 7 more than either uniform grid — by mixing orientations so that the leftover strip along the wall is used and by choosing the orientation that gives the most layers. The top view above shows the pattern.

Frequently asked
How many 400 × 300 × 300 mm boxes fit on a UK pallet?
52 400 × 300 × 300 mm boxes of 400 × 300 × 300 mm fit on a UK pallet (deck 1,200 × 1,000 mm, cargo up to 1,656 mm high), boxes may be laid on any side. That uses 94% of the 2.0 m³ available and weighs about 312 kg.
How high can a UK pallet be stacked?
This plan stacks cargo to 1,800 mm including the 144 mm pallet — 1,656 mm of boxes on a 1,200 × 1,000 mm deck with no overhang, up to 1,000 kg. Many warehouses and carriers set their own limits (1.2 m, 1.8 m or 2.2 m are common), so check the receiving site's rules.
How much does a full load of 400 × 300 × 300 mm boxes weigh?
52 × 6 kg ≈ 312 kg, which is 31% of the 1,000 kg payload — so this load is limited by space, not weight.
How was this number calculated?
By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing all six orientations, stacking with at least 80% base support and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.
