Currently Folded Self Mailers are either a single sheet or multiple sheets folded to letter size. Booklets are described as having front and back covers with a bound edge. The proposed rules define a Folded Self Mailer as a single, continuous sheet of paper with no binding, folded to letter size. It then redefines the dimensions of what is letter sized (201.3.15.3). This means that there can not be any attachments to the single sheet of paper.
Flats (Large Letter) The US flats postage rate is for large envelopes, as used when sending a document of letter or legal size or a magazine through the post.

Size 16 envelopes qualify as flats as do the catalog envelope sizes 1Â¾, 3, 6, 8, 9Â¾, 10Â½, 12Â½, 13Â½, 14Â½, 15, 15Â½.
