How Boxes are Measured
Box dimensions are displayed as: Length x Width x Depth.
Dimensions are always the inside dimensions. This also helps you to accurately determine whether your item(s) will fit.
Length - As you view the base of a box, the length is the longest side.
Width - As you view the base of a box, the width is shortest side.
Depth - At the side of the box, measuring from the base to the top, determines the depth.
