How to Measure Custom Boxes


Whether you need to ship out an off-sized product or to revamp your existing packaging solutions, it is always important to have custom boxes with the correct dimensions. Correct measurements assure you that products will fit correctly, the box itself will fit inside any secondary packaging, and you pay for the right shipping cost. This alone can save your business thousands of dollars in lost revenue.

The easiest rule of thumb in measuring custom boxes is that all measurements are taken from interior dimensions. By always using interior measurements, you’re assured that all products will fit inside your box, regardless of how thick the material is. If you measure the exterior dimensions, you run the risk of items not fitting properly.

Another important thing to remember is that when we measure the dimensions of boxes, we go by length, width, and height. For example, one of the most common mailer box sizes is 9” x 7” x 3”. This means it’s 9 inches long, 7 inches wide, and 3 inches deep. Knowing this measurement informs you that anything within those dimensions can fit inside the custom box.


Packola offers standard boxes in practically every conceivable size. Do you find the standard sizes a little bit too snug or roomy? We’ll create one for you that fits perfectly. If you don’t see the size you need, contact us at or 1-855-PACKOLA and we’ll build it for you.

All our custom boxes are measured the following way:

  • Length – measured side to side
  • Width – measured from back to front
  • Depth – measured from top to bottom


When measuring boxes, refer to this short step-by-step guide:

  1. Lay out the products on a flat surface. Simulate exactly how you want them placed inside a box.
  2. Once you're happy with the alignment and how it looks, measure the space it takes up.
  3. For off-sized items, start by measuring the widest part of product. This way, you’ll have an easier time envisioning how it looks inside a box.
  4. Measure the length from side to side.
  5. Next, measure the width from back to front.
  6. Get the depth from top to bottom.
  7. Finally, add an allowance of .25” (a quarter of an inch) to make the items easy to place and remove. This also gives you enough room for packaging supplies such as bubble wrap or packing peanuts.

It must provide useful information, protection for your product, and be sustainable.
