How many books fit in an Amazon FBA Oversize box?
About 76, for a 21×14×3 cm item weighing 0.4 kg packed into a 157.5×78.7×78.7 cm box with a 31.75 kg limit. Your real number depends on exact dimensions — use the calculator above.
Does it account for the weight limit?
Yes. The simulation stops adding units once the 31.75 kg limit is reached, so the count reflects both space and weight.
