Formula

Volumetric Weight = (L × W × H) / Divisor

Carriers charge by whichever is greater: actual weight or volumetric weight. Volumetric weight = (Length × Width × Height in cm) / 5000 (standard divisor). Lightweight but bulky packages cost more due to space.

Worked Example

Package: 40 × 30 × 20 cm, Actual: 2 kg Volumetric: (40 × 30 × 20) / 5000 = 4.8 kg Billable: 4.8 kg (volumetric > actual) You're paying for 2.8 kg of "air"

What Is Volumetric Weight?

Volumetric weight, also known as dimensional weight, is a pricing technique used by courier companies and freight forwarders to account for the space a package occupies on a vehicle, aircraft, or vessel. Instead of solely charging based on a package's actual weight, carriers charge by whichever is greater: the actual weight or the volumetric weight. This method prevents packages that are light but very bulky from taking up disproportionate space without sufficient revenue generation. The standard calculation involves multiplying the length, width, and height of a package and then dividing the result by a specific divisor. This divisor varies by carrier and mode of transport, with common values being 5000 or 6000 for international air freight when dimensions are in centimeters. Understanding volumetric weight is crucial for businesses, especially those in e-commerce, as it directly impacts shipping expenses and can significantly increase costs for items like clothing, pillows, or certain electronics packed with protective materials. By knowing how volumetric weight is calculated, shippers can optimize packaging strategies to minimize these charges.
  • Volumetric weight accounts for package space, not just mass.
  • Carriers bill based on the greater of actual weight or volumetric weight.
  • Different shipping companies and services may use different divisors.
  • Optimizing package dimensions can reduce volumetric weight charges.

Frequently Asked Questions

What is volumetric weight?

Volumetric weight (or dimensional weight) measures the space a package occupies, not its actual weight. Carriers charge by whichever is higher because lightweight but bulky packages take valuable cargo space.

Which divisor should I use?

5000 is standard for most carriers (DHL, FedEx, UPS, TNT). Some international or economy services use 6000. Check your specific carrier agreement.

How can I reduce volumetric weight charges?

Use smaller packaging, remove excess void fill, use vacuum packaging for soft goods, or consider flat-rate shipping options that ignore dimensions.
