What are the dimensions of a 40 × 40 pallet in millimetres?

40 × 40 in is 1016 × 1016 mm. Overall height depends on the build: 4-3/4 in for the stringer pallet, 5-3/4 in for the block pallet, 4-1/4 in for the skid.

How much does a 40 × 40 pallet weigh?

About 53 lb (24 kg) for the stringer pallet in mixed hardwood, green. The block pallet is about 88 lb. The skid is about 67 lb. Species and moisture change this by up to a third; see the weight guide.

How much weight can a 40 × 40 pallet hold?

It depends on how the pallet is supported: floor-stacked, racked or stacked loads each get a different safe load, and the same pallet can rate several times higher on the floor than in a rack. Certified ratings come from a Pallet Design System analysis or physical testing; see pallet load capacity.

Is 40x40 the same as 40x40?

Same footprint, different pallet. The first number is the stringer (or stringerboard) length, so a 40x40 has 40 in stringers and 40 in top boards. See pallet dimensions explained.
