For a rectangular prism, measure the length, width and height. The length is the longest dimension. 3. Use the following formula to calculate girth where W is the width and H is the height: Girth = 2(W + H) For example, if you had a box that measure 5 inches by 8 inches by 12 inches, 12 inches would be the length. Add 5 and 8 to get 13 and then multiply by 2 and you get 26 inches. This is the girth. Most shipping services charge extra to deliver unusually large packages.
Tape measure. Measure the height and width around the largest point of the package. The USPS uses inches for its package measurement. Therefore, you should take these measurements in inches. For example, assume the height of a package is 50 inches and the width around the largest point of the package is 40 inches. Make sure you measure all the way around the width of the largest point of the package.
