Dimensional Weight Measurements

Carriers charge shippers based on billable weight. Billable weight is defined as the GREATER of either the ACTUAL weight or the DIMENSIONAL weight (dim weight) of a package. Carriers charge this way because they are essentially charging for the space that the package takes on the truck vs. the weight of the package in order to properly account for the costs of delivering the packages.

Understanding Dim Weight Calculations

Dimensional weight is calculated by taking the cubic volume of a shipment and dividing it by a carrier’s dim divisor–a negotiated, variable factor used by all carriers in order to calculate dimensional weight. Multiplying the length x width x height (in inches) and then dividing by the dim divisor will give you the billable weight of a package–the equivalent weight which you are charged when shipping the package.

If you are shipping dumbbell hand weights you may be charged based on the actual weight. However, if you are shipping a large box of feathers, you will be charged based on the dim weight, not the actual weight.

For example, a 20-inch x 20-inch x 10-inch box of feathers might weigh 3 pounds, but the dim weight would be 25 pounds. Since this weight is greater than the actual weight, the dim weight would be used to calculate shipping costs.

Length + Girth Measurement

Calculate girth and length of a package using the parcel dimensions.

Many carriers restrict the maximum length and girth of each package sent. To manage these restrictions they rely on a measure of length + girth. These measurements matter as they ensure your packages fit into standard carrier and fulfillment centers processes as they move from a storage location to their end destination. Our easy-to-use calculator will help you with your planning and calculations!

Understanding Length + Girth Parcel Measurement

When it comes to logistics, the measurement of each side of your parcel is called a “dimension.” Every parcel has three dimensions: length, width, and height. The largest measurement is always considered the “length.”

1. Measure the three parcel dimensions in inches.

Example: 20 inches (Length) x 10 inches (Width) x 10 inches (Height).

2. Add the measurements of the two smallest dimensions together and multiply the result by 2.

Example: 10 inches (Width) + 10 inches (Height) = 20 inches. 20 inches x 2 = 40. So, 40 is the girth of your package.

3. To get the Length & Girth calculation, simply take the longest dimension and add this to the package girth. This result is the combined length and girth of your parcel.

Example: 20 inches (length) + 40 inches (girth) = 60 inches (combined length and girth).
