Discover how to calculate dimensional weight (DIM weight) for your packages to accurately estimate shipping costs. Our free online calculator helps you understand volumetric weight and avoid unexpected surcharges, ensuring cost-effective logistics for both domestic and international shipments.
Formula:
The Dimensional Weight (DIM Weight) is calculated using the following formula:
DIM Weight = (Length × Width × Height) / Divisor
Where:
- Length, Width, Height: The external dimensions of your package (e.g., in inches or centimeters).
- Divisor: A carrier-specific dimensional factor. Common divisors are 139 or 166 for US domestic/international shipments (when dimensions are in inches) and 5000 or 6000 for metric shipments (when dimensions are in centimeters).
