How to Calculate Volumetric Weight: Practical Examples
Shipping costs are often determined not only by actual weight but also by a calculation called volumetric weight, or dimensional weight (DIM weight). This method, widely used by international shippers, considers the space a package occupies rather than its physical weight.
For example, shipping a box of feather pillows versus a box of smartphones: the pillows occupy far more space but weigh less. To ensure fair pricing, carriers calculate shipping costs using volumetric weight for lightweight but bulky items. Understanding dimensional weight calculations in various shipping methods is essential to avoid unexpected fees and manage shipping expenses effectively.

What is Volumetric Weight and Why is it Important?
Definition
Volumetric weight, or dimensional weight (DIM weight), is determined using the dimensions of packaging (length, width, height) to calculate the cubic volume. This volume is then divided by a carrier’s divisor (DIM factor) to convert it into dimensional weight.
Why is Volumetric Weight Important?
- Fair Pricing: Ensures carriers are compensated for the space a package occupies, not just its physical weight.
- Cost Control: Helps businesses predict and manage shipping costs more effectively.
- Encourages Better Packaging: Drives shippers to optimize packaging to reduce costs.

How to Calculate Volumetric Weight for Each Method
The process of calculating dimensional weight is straightforward. Follow these steps:
Step 1: Measure the Package
Measure the length, width, and height of the package’s outer dimensions in consistent units (e.g., centimeters, meters, or inches).
Step 2: Find the Cubic Volume
Multiply the package’s dimensions to calculate its cubic volume.
Step 3: Apply the Carrier’s Divisor (DIM Factor)
Divide the cubic volume by the carrier’s divisor to determine the dimensional weight.
Volumetric Weight for Air Freight
Air freight typically uses a DIM factor of 6000 cm³ = 1 kg or 167 kg per cubic meter (CBM).
Formula for Air Freight:
- Using centimeters:
Vol. Wt (kg) = Length (cm) × Width (cm) × Height (cm) / 6000 - Using meters:
Vol. Wt (kg) = Length (m) × Width (m) × Height (m) × 167 - Using inches:
Vol. Wt (kg) = Length (in) × Width (in) × Height (in) / 366

Practical Example 1: Centimeters
Package dimensions: 500 cm × 450 cm × 350 cm.
- Cubic Volume:
500 × 450 × 350 = 78,750,000 cm³ - Volumetric Weight:
78,750,000 / 6000 = 13,125 kg
Practical Example 2: Cubic Meters (CBM)
Convert to cubic meters:78,750,000 cm³ = 78.75 m³
Apply the formula:78.75 × 167 = 13,162.25 kg (round up to 13,163 kg)
Practical Example 3: Inches
Package dimensions: 50 in × 45 in × 35 in.
- Cubic Volume:
50 × 45 × 35 = 78,750 in³ - Volumetric Weight:
78,750 / 366 = 215.2 kg (round up to 216 kg)
Volumetric Weight for Sea Freight
For sea freight, the divisor is typically 1000 cm³ = 1 kg.
Example:
Package dimensions: 350 cm × 450 cm × 300 cm.
- Cubic Volume:
350 × 450 × 300 = 47,250,000 cm³ - Volumetric Weight:
47,250,000 / 1000 = 47,250 kg

Express Couriers (DHL, UPS, FedEx)
Couriers like DHL, UPS, and FedEx use different DIM factors, such as 5000 cm³ = 1 kg or 139 in³ = 1 lb.
Example:
Package dimensions: 70 cm × 80 cm × 75 cm.
- Cubic Volume:
70 × 80 × 75 = 420,000 cm³ - Volumetric Weight (kg):
420,000 / 5000 = 84 kg

Determining Accurate Shipping Costs
Carriers charge based on the greater of two weights:
- Actual Weight: The physical weight of the package.
- Volumetric Weight: The calculated dimensional weight.

How to Optimize Packaging for Volumetric Weight
Tips for Reducing Volumetric Weight:
- Use Appropriately Sized Boxes:
Avoid oversized boxes that increase volumetric weight unnecessarily. - Redesign Packaging:
Eliminate void fillers and excess materials to minimize dimensions. - Optimize Pallet Usage:
Use compact pallets like the Euro pallet (1200 x 800 mm) instead of larger options to reduce wasted space.
