How to calculate dimensional weight?

Dimensional weight (also known as volumetric weight) is a value adopted by carriers worldwide for calculating shipping rates. It uses a formula of length multiplied by width and height, divided by dim factor (LxWxH)/SF, which may vary from carrier to carrier.

Dim Weight Calculations

To calculate dimensional weight for FedEx divide the cubic size by the FedEx dim divisor. Increase any fraction to the next whole pound or kilogram. The divisor varies by weight unit: 139 (lb) and 5,000 (kg). FedEx Dimensional Weight = (L x W x H) ÷ Divisor.

To calculate dimensional weight for DHL divide the cubic size by the DHL dim divisor. Increase any fraction to the next whole pound or kilogram. The divisor varies by weight unit: 166 (lb) and 5,000 (kg). DHL Dimensional Weight = (L x W x H) ÷ Divisor.

To calculate dimensional weight for UPS divide the cubic size by the UPS dim divisor. Increase any fraction to the next whole pound or kilogram. The divisor varies by weight unit and rate type: 139 (lb) and 5,000 (kg) for Daily Rates; 166 (lb) and 6,000 (kg) for Retail Rates. UPS Dimensional Weight = (L x W x H) ÷ Divisor.

To calculate dimensional weight for USPS divide the cubic size by the USPS dim divisor. Increase any fraction to the next whole pound or kilogram. The divisor varies by weight unit: 166 (lb) and 5,000 (kg). USPS Dimensional Weight = (L x W x H) ÷ Divisor.

To calculate dimensional weight for Canada Post divide the cubic size by the Canada Post dim divisor. Increase any fraction to the next whole pound or kilogram. The divisor varies by weight unit and rate type: 139 (lb) and 5,000 (kg) for Priority and International Rates; 166 (lb) and 6,000 (kg) for Regular Parcels. Canada Post Dimensional Weight = (L x W x H) ÷ Divisor.

More about Dimensional Weight

Dimensional weight kg/cm calculations determine shipping costs based on a package's volume rather than its actual weight. Carriers like FedEx, UPS, USPS, DHL, and Canada Post use dimensional weight to ensure fair pricing for bulky, lightweight shipments. To calculate dimensional weight, carriers measure a package's length, width, and height, then apply a formula (multiplying dimensions and dividing by a dimensional factor).

Dimensional weight significantly impacts shipping rates, especially for larger but lightweight packages. Carriers charge based on the higher value between actual weight and dimensional weight. This ensures accurate pricing, preventing undercharging for spacious yet lighter shipments. Properly calculating dimensional weight is crucial for cost-efficient shipping, as inaccuracies can lead to unexpected costs. Understanding each carrier's dimensional weight rules and accurately measuring packages ensures precise rate calculations and helps businesses optimize shipping strategies while avoiding unforeseen expenses.
