Uline: FAQ Answer

How do you measure a box?

Listed dimensions are always inside dimensions.
The first dimension is length.
Length is always the longest side of the box that has a flap.
The next dimension is width.
The width side also has a flap, but is always the side shorter than the length.
Height is the only dimension without a flap.
The height measurement does not include the flaps.

NOTE: Acceptable manufacturing variance is +/- 1/8".
