How many 12 × 12 × 12 in boxes fit on a UK pallet?
12 × 12 × 12 in boxes of 305 × 305 × 305 mm (also called 1 cubic foot boxes, small moving boxes) 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. 64% of the space used, 5 layers high, about 270 kg (27% of payload). Open this load in the 3D planner →

The answer in detail
The one-cubic-foot box (12 × 12 × 12 in, about 305 mm) is the standard small US shipping and moving carton. Being a cube, its count is simple grid arithmetic.
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 × 5 high = 45. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (45).

Frequently asked
How many 12 × 12 × 12 in boxes fit on a UK pallet?
45 12 × 12 × 12 in boxes of 305 × 305 × 305 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 64% of the 2.0 m³ available and weighs about 270 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 12 × 12 × 12 in boxes weigh?
45 × 6 kg ≈ 270 kg, which is 27% 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.
