Dimensional weight is a pricing technique used by shipping carriers that takes into account package density. It's calculated by multiplying length × width × height and dividing by a dimensional factor (usually 5000 for cm³/kg or 139 for in³/lb).
Carriers use dimensional weight to ensure they are fairly compensated for lightweight but bulky packages that take up significant space in their vehicles, making shipping operations less efficient.
Our calculator uses industry-standard dimensional factors and formulas used by major carriers. The results are highly accurate for estimation purposes, though actual shipping costs may vary based on carrier-specific policies and surcharges.
Use the measurement units required by your shipping carrier. Most international shipments use centimeters and kilograms, while domestic US shipments typically use inches and pounds. Our calculator supports both systems.
