Dimensional Weight (Volumetric Weight) Calculator
Calculate the dimensional (volumetric) weight of a package for shipping cost estimation based on its dimensions and carrier divisor.
Calculate the dimensional (volumetric) weight of a package for shipping cost estimation based on its dimensions and carrier divisor. Enter your Length, Width, Height, Dimensional Divisor to get an instant dimensional weight. Formula: (length * width * height) / dimensional_divisor.

How It Works
How It Works
This calculator estimates the shipping weight of a package based on how much space it takes up, not just how heavy it is. Shipping companies often charge based on size when a package is large but lightweight.
It multiplies the package’s length, width, and height to find its total volume. Then it divides that volume by the dimensional divisor provided by the carrier to calculate the dimensional (volumetric) weight.
- Step 1: Multiply length × width × height to get the package volume.
- Step 2: Divide the volume by the dimensional divisor (such as 139 or 5000).
- The formula used is: (length * width * height) / dimensional_divisor.
- The result is the dimensional weight used for shipping charges.
Understanding the Results
The result shows the dimensional weight of your package. Carriers compare this number to the actual scale weight and charge you based on whichever is greater.
If you use inches with a divisor like 139, the result is in pounds. If you use centimeters with a divisor like 5000, the result is in kilograms.
- A higher result means higher shipping costs.
- Large but lightweight packages often have higher dimensional weight.
- Use 139 for inches (commonly in the US).
- Use 5000 for centimeters (commonly for international shipping).
Frequently Asked Questions
What is dimensional (volumetric) weight?
Dimensional weight, also called volumetric weight, is a pricing method used by shipping carriers to account for the space a package occupies rather than its actual scale weight. It is calculated using the package's length, width, height, and a carrier-specific dimensional divisor. Carriers charge based on whichever is greater: the actual weight or the dimensional weight.
When should I use the Dimensional Weight Calculator?
You should use this calculator when shipping packages that are large but lightweight. Carriers such as UPS, FedEx, and DHL apply dimensional weight pricing to ensure they are compensated for cargo space used. This calculator helps you estimate your billable shipping weight before sending the package.
What dimensional divisor should I use?
The dimensional divisor depends on the carrier and measurement system. In the United States, a common divisor is 139 when dimensions are measured in inches, resulting in weight in pounds. International shipments often use 5000 when dimensions are in centimeters, resulting in weight in kilograms. Always confirm the correct divisor with your shipping provider.
What units should I enter for length, width, and height?
Use consistent units that match your dimensional divisor. If you are using a divisor of 139, enter dimensions in inches to get the result in pounds. If using 5000, enter dimensions in centimeters to get the result in kilograms. Mixing units will produce incorrect results.
Does dimensional weight replace actual weight?
Dimensional weight does not replace actual weight but is used for comparison. Shipping carriers calculate both the actual weight and the dimensional weight, then charge based on the higher value. This ensures fair pricing for both heavy compact items and large lightweight packages.
Can reducing package size lower shipping costs?
Yes, reducing the package dimensions can significantly lower dimensional weight and overall shipping costs. Even small reductions in length, width, or height can decrease the calculated volumetric weight. Using appropriately sized packaging helps avoid unnecessary charges.
