All of our dimensions are given as inside measurements to make it easy for you to determine if your product will fit. The dimensions are given as Length × Width × Depth.
Here is our advice for finding the perfect size!
- Length is the measured side-to-side. For mailer boxes, this is the side on which the box opens and hinges.
- Width is measured front to back
- Depth is measured from top to bottom
When measuring your contents to determine the box size you need, we recommend adding at least .25 inches to your actual product dimensions, for ease in packing and unpacking.
If you'd like to know the corresponding outside dimensions, here are the dimensions for boxes using our popular E Flute:
Internal Length + .625" = Outside Length
Internal Width + .1875" = Outside Width
Internal Depth + .125" = Outside Depth
There is a tolerance of +/- .125" on all measurements.
