How to Measure a Perfect Box Size?

One thing that matters the most in manufacturing a custom box is its size. If it’s size is not properly measured, then it means that your product is not going to sit right in the box.

To manufacture a perfect box, you must have to know its size, which later helps in manufacturing the packaging itself. There are three main dimensions in measuring of your product:

  • Length (L)
  • Height (H)
  • Width (W)


  • Box dimensions are measured in length, width, and height. In other words, 14″ (L) x 11″ (W) x 4″ (H) means 14″ (L) x 11″ (W) x 4″ (H).
  • In order to assist you, please let us know if the dimensions of your box are those of the inner or outer box.
