Worried about your package’s size and shipping price? At PostPlan, we’ve got you covered!

If you are an online seller, you have probably experienced that some of the stuff you send doesn’t always fit neatly into a flat rate box which makes the packing and shipping process pretty hard. When the dimensional weight comes into play, it’s flat-out complicated.

As your eCommerce fulfillment center, we’re here to help you calculate dimensional weight. But first, let’s start with a quick overview of how dimensional weight works.

How dimensional weight works?

In order to determine the dimensional weight of the package, first measure the length, width, and height of the package in centimeters using the longest point on each side. Please take into account any bulges or misshaped sides.

You can calculate the cubic size of a package by multiplying its length, width, and height. You can read the example below.

We use the following conversion to work out the cubic weight.
(L cm A— W cm A— H cm)/5000

Example 45 x 45 x 45cm = 91,125 / 5000 = 18kg

It’s important to keep in mind that most shipping carriers will have you round to the nearest whole number when calculating the dimensional weight of your package.
