How do you measure a box?

To measure a box, you will need to use a ruler or measuring tape to measure the length, width and height of the box. Listed dimensions are always inside dimensions.

The first dimension to measure 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.
Measure the height of the package. Height is the only dimension without a flap. Measure the standing side of the box from top to bottom. The height measurement does not include flaps.

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

Find the right box for you with the Uline Box Guide.
