The standard size of a wooden shipping pallet is 40 inches by 48 inches. The two types of wooden pallets are stringer and block pallets, both of which are similar but vary slightly in their construction.
Both types of wooden pallets are constructed with the same size of wood; however, stringer pallets are built with plastic or metal stringers, while block pallets are made with blocks of wood. Two-way pallets have two forklift openings located at the bottom of the pallet, while four-way pallets have four openings to make them accessible from all sides with a forklift. Partial four-way pallets have standard openings on two ends and smaller openings on the remaining two ends.
