How to Determine the Size of a Box

Understanding the dimensions of your box is similar to packing a suitcase for a trip. Begin by collecting the contents you wish to ship in your package.

  1. Lay out the item or items on a table or flat surface just as you wish to display them in the final packaging.

  2. Measure and record the L x W x D.

  3. Finally, add 1/16 - 1/18" to each measurement. This will ensure every item is packaged just right.

Expert tip: We strongly recommend that you measure your dimensions at least twice to ensure every specification is correct.
