Two ways cargo can be measured
Actual weight is what a scale records. Volumetric weight is a calculated measure of the space a package occupies. Depending on the carrier and service, chargeable weight may use the greater result.
The general idea
A common method multiplies length by width by height and divides by a carrier-specific factor. The exact divisor varies by carrier and transport method, so it must be confirmed in the quote rather than assumed from an online example.
A simple example
Imagine two cartons with the same actual weight. One is compact and the other is twice as large. The larger carton uses more aircraft or vehicle capacity, so its space-based calculation may affect the quote even though the scale reading is unchanged.
How to measure accurately
Measure the longest outside edges after final packing. Include bulges, handles or protective material. Use centimetres or inches consistently and identify the unit on your quote request.
- Measure after packing
- Use the furthest outside points
- Record each package separately
- Share actual scale weight as well
Avoid unnecessary volume
Choose packaging that protects the cargo without leaving excessive empty space. Do not compromise safety to reduce size; suitable cushioning and structural strength remain essential.
