Crate size and volumetric weight calculator

Use this volumetric weight calculator to estimate the packed size of furniture, design pieces or artworks. Enter the object’s dimensions to calculate an estimated crate volume, then include the packed gross weight to compare freight charging calculations.

Crate weight is estimated from the surface area of the crate.

Indicative conversions only. You are responsible for verifying them yourselves. Chargeable weight depends on the packed gross weight, dimensions and carrier’s charging rules. Confirm ratios, minimum charges and rounding before quoting. The sea comparison is for LCL shipments sharing a container.

What volumetric weight is

Volumetric weight expresses the space a shipment occupies as a weight. A large, light crate may therefore be charged at more than its actual weight.

For air and courier services, the carrier generally compares volumetric weight with packed gross weight and uses the greater figure.

How it is calculated

Multiply the packed length, width and height in metres to calculate volume in cubic metres. One cubic metre is approximately 35.315 cubic feet.

For air freight, a common calculation is volume in cubic metres × 167, giving volumetric weight in kilograms. Courier services commonly use × 200. Road freight uses the carrier’s agreed ratio.

For LCL sea freight using a weight-or-measure basis, compare the volume in cubic metres with the gross weight in tonnes. The larger figure determines the charging units.

Allowing for the crate

The packed dimensions include protective materials, timber and any skids beneath the crate.

The allowances shown are starting estimates. The piece, packing method and journey determine what is needed. Confirm the finished external dimensions and packed gross weight before booking freight.

Keep the dimensions with the asset

In Lucett, descriptions, dimensions and photographs stay with the asset’s record, giving your team a reference for the next quote, crate or move.
