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.
USPS Shipping Girth. Use a measuring tape to find the height, width and length of the box in inches. For USPS shipping, the length is always the longest dimension of the box. Multiply the width by 2 and multiply the height by two. Add the results together to find the girth. For example, suppose you measure the height of a box as 10 inches, the width as 12 inches and the length as 60 inches. Multiply 10 inches by 2 and 12 inches by 2. Add the results. The total of 44 inches is the girth of the box. Add the 60-inch length to the 44-inch girth for a total of 104 inches.
