About These Packaging Calculators
Getting your packaging right directly impacts your shipping costs. Oversized boxes trigger DIM weight charges, meaning you pay for the space your package occupies rather than its actual weight. These tools help you find the right box size, calculate dimensional weight before you ship, and plan pallet loads efficiently. All calculations use carrier-published DIM divisors and standard industry formulas.
DIM weight is calculated as length times width times height, divided by the carrier DIM divisor. UPS and FedEx use a divisor of 139 for domestic shipments (cubic inches per pound). USPS applies DIM weight only to Priority Mail packages over one cubic foot, using a divisor of 166. If your DIM weight exceeds actual weight, the carrier charges the DIM weight. Choosing a box that fits your product snugly is the simplest way to avoid paying for air.
The box size calculator works in reverse: enter your product dimensions and it finds the smallest standard box that fits. The pallet calculator helps logistics teams figure out how many cases fit on a standard 48x40 pallet at a given stack height, which is useful for freight planning and warehouse space estimates.
DIM divisors and carrier policies change periodically. Always verify with your carrier before finalizing packaging decisions for high-volume shipments.
