Find the billable (DIM) weight of any package. Enter dimensions, get the number carriers use to price it.
Ballpark estimates. Verify exact rates with each carrier before shipping.
Dimensional weight equals length times width times height, divided by the carrier's DIM divisor. UPS and FedEx domestic ground use 139. USPS and international shipments typically use 166. Carriers charge the greater of dimensional weight and actual weight, rounded up to the next whole pound, which is how a 2-lb pillow in a 18x12x10 box becomes a 16-lb billing line item.
Estimate rates and DIM weight with our free shipping tools.
A calculated weight based on package volume: L x W x H divided by the DIM divisor. If that number is larger than your actual weight, carriers charge for it instead.
139 for UPS and FedEx domestic ground shipments. USPS Ground Advantage and most international services use 166.
A truck full of feather pillows still only hauls so many boxes. DIM pricing lets carriers charge for the space a package occupies, not just how much it weighs.
Use the smallest box that fits. Shaving two inches off each dimension of an 18x12x10 box cuts its DIM weight from about 16 lbs to about 9 lbs at a divisor of 139.
Yes. Carriers round up to the next whole pound, so a DIM weight of 9.1 lbs bills as 10 lbs.
