Calculating Package Weight and Package Size

Here at TNT, we want to ensure our customers are fully informed with everything they need to know about our services. So if you’re unsure about anything from parcel weight restrictions to calculating package weight, here’s what you need to know:

Calculating Volumetric Weight

For larger yet lightweight parcels and packages, we charge you for the space that they take up rather than their actual weight. This means you need to work out its volumetric weight. When calculating the volumetric weight, you need to initially work out the volume of your package and then multiply this by the relevant conversion factor. For more detail see below:
