What is Dimensional Weight

Stackry is open for business as usual, while following health guidelines. See our latest COVID-19 updates.

Experienced internet shoppers are familiar with the fact that all international carriers base their shipping rates on the greater of actual weight and dimensional weight. Actual weight is the weight of the package when put on a scale. On the contrary, dimensional weight is based on the size of the package. By charging only by weight, lightweight, low density packages become unprofitable due to the amount of space they take in proportion to their actual weight. That is why the concept of dimensional weight has been adopted. 

You should know that the volume used to calculate dimensional weight is not absolutely representative of the true volume of the package. The freight carrier will measure the longest dimensions in each of the three axis (x,y,z) and use these measurements to determine the package volume. 

How can you calculate dimensional weight? It is simple. Here’s the formula: (Length x Width x Height) / (Dimensional Factor). Measurements can be both in inches and centimeters but you must use the appropriate dimensional factor. Stackry's dimensional factor is 166.
