  2. Enter the dimensions of the carton or container, it should me measured in centimetres (CM).
  3. Enter the weight of the item, try to be as accurate as you can.
  4. Press “Calculate”.

What the results will tell you

  1. The first column will show you the dimensions used in the calculations. These will match those that you have entered on the form to the left.
  2. The Real Weight will show you the weight you have entered.
  3. The Volumetric Weight will show you the calculated weight based on the object's dimensions.
  4. You will then be told what weight (Real or Volumetric) will be used by the carrier, the final weight will be the higher of the two..
