How to Calculate UPS Dimensional Weight
UPS publishes different divisors for U.S. Daily and Retail Rates. Here is how that changes the answer.
Choose the rate type first
UPS publishes 139 for Daily Rates and 166 for Retail Rates in its U.S. dimensional-weight guidance. Account contracts can contain additional rules, so treat the public preset as a starting point.
| Rate type | Published divisor | 3,888 in³ example |
|---|---|---|
| Daily Rates | 139 | 28 lb after rounding |
| Retail Rates | 166 | 24 lb after rounding |
