Volumetric weight (also called dimensional weight) is a pricing technique used by shipping carriers to account for the space packages take up in their vehicles. Carriers charge based on whichever is greater: the actual weight or the volumetric weight. This calculator helps you quickly determine the billable weight of your shipments.
E-commerce sellers calculating shipping costs before listing products. Freight forwarders quoting customers on international shipments. Product packaging optimization to reduce dimensional weight. Comparing shipping rates across different carriers.
Enter your package dimensions (length, width, height) and actual weight. Select your unit of measurement and the divisor (5000, 6000, 7000, etc.). The calculator shows both the volumetric weight and the billable weight. For multiple packages, add each one to get the total billable weight. Enter your shipping rate to estimate the total cost.
Volumetric weight (or dimensional weight) is a way shipping carriers charge for the space a package occupies, not just its weight. Carriers charge the greater of actual weight or volumetric weight. This is why a large, light box can cost more to ship than a small, heavy one.
The divisor determines how many cubic centimeters equal one kilogram. A smaller divisor (5000) means higher volumetric weight (worse for shippers). DHL, FedEx, and UPS typically use 5000 for international express. Many economy services and postal services use 6000 or 7000.
Use the smallest possible box that fits your product safely. Remove unnecessary packaging materials. For soft goods, use vacuum compression. Consider flat-rate shipping options if they're cheaper. Consolidate multiple items into one package when possible.
Virtually all major carriers use dimensional weight: DHL, FedEx, UPS, USPS (for certain services), and most freight companies. The specific divisor varies by carrier and service level. Always check with your carrier for their current rules.
