UK Pallet Calculator — 1200 × 1000 mm

For operations using a 1200 × 1000 mm pallet footprint, calculate cases per layer, number of layers, total weight and utilization from the actual carton dimensions.

By PackMize · Published

Quick answer: On the PackMize 1200 × 1000 mm Industrial / ISO planning preset, 400 × 300 × 250 mm cartons fit 60 per pallet: 10 per layer × 6 layers under an 1800 mm total-height limit.

A 1200 × 1000 mm planning page, not a claim of one universal UK pallet

UK logistics uses more than one pallet system. This page targets searches for the commonly used 1200 × 1000 mm industrial footprint and deliberately avoids claiming that every UK pallet has the same construction, height or load rating. If your operation uses a 1200 × 800 EPAL pallet or a pool-specific pallet, choose that exact profile instead.

Worked example: 400 × 300 × 250 mm cartons

InputValue
Planning footprint1200 × 1000 mm

Carton400 × 300 × 250 mm
Carton weight8 kg
Result60 cartons · 10/layer · 6 layers
StatusPROVEN OPTIMAL for the modelled constraints

The wider 1000 mm deck changes the footprint arrangement compared with an 800 mm Euro pallet. This is why pallet footprint must be part of the calculation rather than inferred from a generic “standard pallet” label.

Which inputs should come from your operation?

Use the measured pallet base height, allowed total load height, pallet tare and safe operational payload supplied by your pallet provider or internal standard. Those operational values can matter more than a nominal pallet family name.

Compare the result with the Euro pallet

Using the same 400 × 300 mm carton footprint, the 1200 × 1000 mm deck fits 10 per layer while the 1200 × 800 mm EPAL deck fits 8. That comparison is a clean illustration of why layer geometry is more useful than pallet volume alone.

Assumptions and data sources

PackMize separates published reference data from planning assumptions. Always replace a preset with the specification of the pallet, container, sheet or stock you will actually use when operational accuracy matters.

ISO 6780:2003 — International standard covering principal dimensions and tolerances of flat pallets; useful context for dimensional planning.

Frequently asked questions

Is 1200 × 1000 mm the only UK pallet size?

No. UK supply chains use multiple pallet formats and pooling systems. This page is specifically for a 1200 × 1000 mm planning footprint.

Can I enter a different pallet height or payload?

Yes. Use a custom profile whenever the preset does not match the actual pallet specification.

Can overhang be modelled?

The public pallet calculator assumes the usable rectangular deck dimensions you enter. If overhang is permitted, model the intended usable footprint deliberately and validate the operational rule separately.
