About the DIM Weight Calculator

The DIM Weight Calculator was built by a team of eCommerce and logistics professionals who were tired of unexpected shipping charges. We noticed that many small businesses and independent sellers were losing their profit margins because they didn't fully understand how Dimensional Weight (DIM Weight) algorithms worked for major carriers.

Our mission is to provide a fast, accurate, and free tool to help you calculate your true billable weight before you print a shipping label. We maintain up-to-date DIM divisors for UPS, FedEx, DHL, and Canada Post so you can ship with confidence.
