Package Dimension Rounding for UPS and USPS
I've always rounded up my measurements, for example whether it was 12.1" or 12.9", I would put 13".
After reading another post, it got me wondering and I did some searching:
From the UPS Site:
- Round Up
Round to the nearest whole number when taking your measurements. For example, 1 to 1.49 will be considered 1, and 1.5 to 1.99 will be considered 2.
However for USPS, there's is a bit more difficult to navigate for what we use here on eBay:
Their example: A box measures 20.75" x 20.25" x 20"
Priority Mail dimensional weight for rectangular shaped parcels to zones 1–9.
- Measure the length, width, and height in inches. Round off 1 each measurement to the nearest whole inch (length = 21, height = 20, and width = 20)
But this is under Retail- Priority Mail page.
I cannot find anything under Ground Advantage that has this type of information. Does it follow the same rule?

·1 year agoYes, Ground Advantage follows the same dimensional rounding as Priority. See section 1.4.2: https://pe.usps.com/text/dmm300/283.htm
The exception for both services is measurements for USPS Cubic rates, which round down to the nearest 1/4 inch. Just to keep things interesting.
1.3.3 Determining Cubic Tier Measurements for Rectangular and Nonrectangular Parcels
Follow these steps to determine the cubic tier measurement for rectangular and nonrectangular parcels:
1.3.4 Determining Cubic Tier Measurement for Soft Pack and Padded Envelopes
Cubic-tier measurements for soft pack (poly, plastic, cloth, or similar soft packaging) and padded envelopes are based, in inches, on the outside dimensions of length plus width of the original packaging material. Pleated (e.g., expandable) mailpieces must meet the measurement guidelines in 1.3.3 to be eligible for cubic pricing. Determine cubic-tier measurements as follows:

Cubic for Priority is similar, bt with a size limit of .5 cubic foot: https://pe.usps.com/text/dmm300/223.htm
