DMM TOC > 100 Retail Letters, Cards, Flats, and Parcels|
[6-2-14] Letter-size mail is:
a. Not less than 5 inches long, 3-1/2 inches high, and 0.007-inch thick.
b. Not more than 11-1/2 inches long, or more than 6-1/8 inches high, or more than 1/4-inch thick.
c. Not more than 3.5 ounces (First-Class Mail letter-size pieces over 3.5 ounces pay flat-size prices).
d. Rectangular, with four square corners and parallel opposite sides. Letter-size, card-type mailpieces made of cardstock may have finished corners that do not exceed a radius of 0.125 inch (1/8 inch). See Exhibit 126.96.36.199.
b. Is polybagged, polywrapped, enclosed in any plastic material, or has an exterior surface made of a material that is not paper. Windows in envelopes made of paper do not make mailpieces nonmachinable. Attachments allowable under applicable eligibility standards do not make mailpieces nonmachinable.
d. Contains items such as pens, pencils, keys, or coins that cause the thickness of the mailpiece to be uneven; or loose keys or coins or similar objects not affixed to the contents within the mailpiece. Loose items may cause a letter to be nonmailable when mailed in paper envelopes; (see 601.3.3).
e. Is too rigid (does not bend easily when subjected to a transport belt tension of 40 pounds around an 11-inch diameter turn).
f. For pieces more than 4-1/4 inches high or 6 inches long, the thickness is less than 0.009 inch.
[6-2-14] Flat-size mail is:
a. More than 11-1/2 inches long, or more than 6-1/8 inches high, or more than 1/4 inch thick, except as allowed for EDDM-Retail flats under 140. For general retail mailability, all pieces 1/4 inch thick or less must be a minimum of 5 inches long and 3-1/2 inches high and 0.007 inch thick.
b. Not more than 15 inches long, or more than 12 inches high, or more than 3/4 inch thick.
d. Rectangular with four square corners or with finished corners that do not exceed a radius of 0.125 inch (1/8 inch). See Exhibit 188.8.131.52.
The length of a flat-size mailpiece is the longest dimension. The height is the dimension perpendicular to the length.
[6-2-14] Flat-size pieces must be flexible. Boxes—with or without hinges, gaps, or breaks that allow the piece to bend—are not flats. Tight envelopes or wrappers that are filled with one or more boxes are not flats. At the customer's option, a customer may perform the following test on their own mailpieces. When a postal employee observes a customer demonstrating that a flat-size piece is flexible according to these standards, the employee does not need to perform the test. Test flats as defined in 201.4.3.
Flat-size mailpieces must be uniformly thick so that any bumps, protrusions, or other irregularities do not cause more than 1/4-inch variance in thickness. When determining variance in thickness, exclude the outside edges of a mailpiece (1 inch from each edge) when the contents do not extend into those edges. Also, exclude the selvage of any polywrap covering (see 201.5.3 from this determination. Mailers must secure nonpaper contents to prevent shifting of more than 2 inches within the mailpiece if shifting would cause the piece to be nonuniform in thickness or would result in the contents bursting out of the mailpiece (see 601.3.3).
USPS categorizes parcels into one of three mail processing categories: machinable, irregular, or outside parcel. These categories are based on the physical dimensions of the piece, regardless of the placement (orientation) of the delivery address on the piece.
[6-2-14] All parcels must be large enough to hold the required delivery address, return address, mailing labels, postage, barcode, endorsements, and other mail markings on the address side of the parcel. No mailpiece may weigh more than 70 pounds or measure more than 108 inches in length and girth combined, except Standard Post, which may not measure more than 130 inches in length and girth combined. For parcels, length is the distance of the longest dimension and girth is the distance around the thickest part. Lower size or weight standards apply to mail addressed to some APOs and FPOs subject to 703.2.0 and 703.4.0 and for Department of State mail, subject to 703.3.0. For additional information on machinable, irregular, and outside parcels see 201.7.0.
[6-2-14] With the exception of USPS-produced Flat Rate Envelopes and Boxes, two or more packages may be mailed as a single parcel, if they are about the same size or shape, if they are securely wrapped or fastened together, and if they do not together exceed the weight or size limits.
4.0 Additional Physical Standards for Priority Mail Express
[6-2-14] Each piece of Priority Mail Express may not weigh more than 70 pounds. The combined length and girth of a piece (the length of its longest side plus the distance around its thickest part) may not exceed 108 inches. Lower size or weight standards apply to Priority Mail Express addressed to certain APO/FPO and DPOs. Priority Mail Express items must be large enough to hold the required mailing labels and indicia on a single optical plane without bending or folding.

The address side of a card is the side bearing the delivery address and postage. The address side may be formatted to contain a message area. Cards that do not contain a message area on the address side are subject to the applicable standards for the price claimed. For the purposes of 6.2, miscellaneous graphics or printing, such as symbols, logos, or characters, that appear on the address side of cards not containing a message area are generally acceptable provided the items are not intended to convey a message.
6.2.9 Double Cards
A double card (a double stamped card or double postcard) consists of two attached cards, one of which is designed to be detached by the recipient and returned by mail as a single card. Double cards are subject to these standards:

b. A double card must be folded before mailing and prepared so that the address on the reply half is on the inside when the double card is originally mailed. The address side of the reply half may be prepared as Business Reply Mail, Courtesy Reply Mail, meter reply mail, or as a merchandise return service label.
c. Plain stickers, seals, or a single wire stitch (staple) may be used to fasten the open edge at the top or bottom once the card is folded if affixed so that the inner surfaces of the cards can be readily examined. Fasteners must be affixed according to the applicable preparation requirements for the price claimed. Any sealing on the left and right sides of the cards, no matter the sealing process used, is not permitted.
