Volumetric size and volumetric weight are calculations which are used to consider whether a service is available for the delivery of your parcel and the rates which will be charged.

For the standard services this is currently determined on volumetric size only. However for the express services both volumetric size and volumetric weights will be used to determine the availability and rate for the service.

### Volumetric Size

Volumetric size is calculated by multiplying the height and width of your parcel by two, and then adding the length of the longest side. Written as a calculation this is expressed as 2 x (width + height) + length. For example a parcel which has the following dimensions - length: 30cm, width: 10cm, height: 20cm - will have a volumetric size of 90cm.

### Volumetric Weight

Volumetric weight is calculated using a different formula to volumetric size. This weight is calculated by multiplying the parcel's length by its width and by its height and dividing this sum by 5000. Written as a calculation this is expressed as length x width x height / 5000.

For example a parcel which has the following dimensions - length: 30cm, width: 10cm, height: 20cm - will have a volumetric weight of 1.2kg
