Box dimensions from volume
Turn a target volume into box dimensions with the proportions you want.
How it works
Length = ∛(volume ÷ (width ratio × height ratio)); width and height follow the ratios.
Tip
A ratio near 1 : 0.75 : 0.5 is a common, material-efficient shipping shape.
Questions
Why does shape matter?
Very long or flat boxes use more board for the same volume.
Does it include board thickness?
No, these are inside dimensions.
