Dimensional Weight Calculator

In one line: Find out whether your parcel bills by its size instead of its weight — before the carrier surprises you with a higher invoice.

When to use

  • Pricing freight for a light but bulky product
  • Comparing carriers that use different divisors (5000 vs 6000)
  • Deciding whether smaller packaging would lower your shipping bill

Inputs

Field Notes
Length × Width × Height Outer carton dimensions in cm
Actual weight Gross parcel weight in kg
Carrier divisor Volumetric factor, e.g. 5000 (express) or 6000 (economy)

Outputs

  • Volumetric weight (L × W × H ÷ divisor)
  • Billable weight (the greater of actual vs volumetric)
  • Carrier comparison: how the billable weight shifts across divisors

Steps

  1. Open https://www.niceggie.com/tools/dimensional-weight
  2. Enter length, width, height, and actual weight
  3. Choose your carrier divisor (5000 or 6000)
  4. Read the billable weight and adjust packaging if volumetric dominates

When does size win?

A parcel bills by volume whenever its density falls below the divisor threshold — roughly 200 kg/m³ at divisor 5000. Light, oversized items (pillows, lampshades, foam) almost always bill by volumetric weight, so shrinking the box matters more than shaving grams.

FAQ

Why is my billable weight higher than the actual weight?

Carriers charge for the space a parcel occupies, not just its mass. If the volumetric weight exceeds the actual weight, the volumetric figure becomes the billable weight. Reduce void space or use a smaller carton to bring it down.

Which divisor should I use?

Express services typically use 5000, while economy or freight services often use 6000. A higher divisor produces a lower volumetric weight, so always confirm the exact divisor in your carrier's rate card before quoting.
