Overview
Measuring Length Plus Girth (201.7.0)
For parcels, length is the measurement of the longest dimension and girth is the distance around the thickest part (perpendicular to the length).
Except for USPS Retail Ground and Parcel Select, no mailpiece may measure more than 108 inches in length and girth combined. USPS Retail Ground and Parcel Select pieces measuring over 108 inches but not more than 130 inches in combined length and girth are mailable at the applicable oversized price (253.1.0).
The Postal Service classifies parcels as machinable parcels, irregular parcels, or nonmachinable parcels.
Machinable Parcels (201.7.5)
If you prepare your parcels so that they can be processed on Postal Service equipment, your mail is “machinable.” Machinable parcels must meet specific standards for size, shape, content, and weight.
Minimum weight: 6 ounces (3.5 ounces for parcels prepared under 201.7.5.2).
Maximum weight: 25 pounds (35 pounds for Parcel Select and Parcel Return Service parcels that do not contain books and other printed matter). Lower weight limits apply to First-Class Package Service, USPS Marketing Mail, and Bound Printed Matter.
Dimensions:
Soft goods wrapped in paper or plastic bags and printed matter are machinable only if all packaging standards in 601 are met.
Irregular Parcels (201.7.6)
Irregular parcels include parcels that do not meet the dimensional criteria of machinable parcels and other parcels that cannot be processed by parcel sorters, including:
Nonmachinable Parcels (201.7.7)
Nonmachinable parcels exceed any of the maximum dimensions for machinable parcels. This category also includes certain high-density items, cartons containing more than 24 ounces of liquids in one or more glass containers, cartons containing 1 gallon or more of liquid in metal or plastic containers, and items in 201.7.7.
First-Class Package Service (201.8.3)

Oversized Price: pieces measuring more than 108 inches in combined length and girth, but not more than 130 inches in combined length and girth, are mailable at the applicable Parcel Select oversized price. Oversized pieces are not subject to nonmachinable prices.
Balloon Price: Parcel Select pieces measuring more than 84 inches in combined length and girth, but not more than 108 inches in combined length and girth, and weighing less than 20 pounds are mailable at the price equal to that of a 20-pound parcel for the zone to which the parcel is addressed.

- Parcels with characteristics (such as inadequate packaging) that could result in damage to the contents of the mailpiece, other parcels, or postal machinery if mechanical sortation is used.
Examples of Balloon Price, Oversized Price, and Priority Mail Dimensional Weight |
Priority Mail (zones 1–4) and Parcel Select (all zones) Balloon Price if: | | Nonmachinable Price: No Balloon Price: Yes Oversized Price: No In this example, length and girth is 90 inches. |
Priority Mail (zones 5-9) Dimensional weight for rectangular shaped parcels. For Priority Mail dimensional weight for nonrectangular shaped parcels to zones 5–8, see 223.1.6. | | Dimensional Weight: Yes Balloon Price: No In this example the dimensional weight for a package to zones 5–9 is 44 pounds. - Round off each measurement to the nearest whole number (length = 21, height = 20, and width = 20).
- Multiple length x height x width (21 x 20 x 20) = 8,400 cubic inches
- If more than 1,728 cubic inches, divide the result by 194 and round up to the next whole number to determine dimensional weight (8,400/194 = 43.29). Dimensional weight = 44 pounds.
