Determine Dimensional Weight
Dimensional weight reflects package density, which is the amount of space a package occupies in relation to its actual weight. Dimensional weight may apply to all international package services.
Determine the package dimensions in inches. For each dimension, measure at the longest point, rounding each measurement to the nearest whole number (for example, 1.00 to 1.49 will be considered 1, and 1.50 to 1.99 will be considered 2). Measure the length, width, and height of the package at its extreme points. If the package has a bulge or is irregularly shaped, include in the measurements the bulge or irregular aspects of the package. Multiply the package length by the width by the height. The result is the size in cubic inches. When you have the size in cubic inches, divide it by 139 (international standard) to determine the dimensional weight.
Dimensional Weight = (L X W X H)/139
Determine Billable Weight
International shipping rates are based on billable weight. Billable weight compares a package's actual weight to its dimensional weight. The greater of the two is the billable weight and should be used to calculate the shipping rate.
