How to Measure a Box

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

  1. The first dimension to measure is length.  Length is always the longest side of the box that has a flap.
  2. The next dimension to measure is width.  The width side also has a flap, but is always the side shorter than the length.  
  3. 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".
