SEPTEMBER 8, 2009 The Postal Service adopts new
Mailing Standards of the United States Postal
Service, Domestic Mail Manual (DMM) to reflect
changes to the construction and sealing of
letter- sized booklets mailed at automation,
presorted machinable or carrier route letter
prices. We also adopt a definition of booklets
and clarify weight standards for letter- sized
mail.

Booklets definition Multiple sheets of paper
bound together on one edge to form a spine may
be perfect-bound or permanently fastened with
staples (saddle stitched) or another method that
creates a uniformly thick mailpiece. Larger
booklets may be folded to letter-size so long as
final mailpiece remains uniformly thick. Spiral
bindings are not machinable and do not qualify
for automation prices.

Booklets º Height 3.5 inches to 6 inches º
Length 5 inches to 10.5 inches º Thickness
0.009 inch to 0.25 inches measured at the booklet
spine º Aspect ratio within 1.3 to 2.5 º
Maximum weight 3 ounces
Note some booklet designs have shorter maximum
lengths

The current maximum weight of 3 ounces has not
changed and is applicable to all mailpieces
prepared without envelopes. However, to improve
machinability we recommend reducing the length of
3-ounce booklets to a final trim size of 9 inches.

Cover stock requirements vary with 40-pound
minimum basis weight for folded booklet designs
and 60- or 70-pound minimum basis weight for
pieces longer than 9 inches. The use of paper
that is 10 pounds heavier than the required
minimum basis weight is recommended for better
processing performance. We strongly recommend
using a minimum of 70-pound paper as cover stock
on mailpiece designs that approach maximum
booklet dimensions.

The bottom edge of booklets must be a bound edge
or fold unless the mailpiece is prepared as an
oblong booklet. Oblong booklets must be
prepared with a spine on the leading edge.
Oblong booklets with the spine on the trail edge
are non machinable.

Tabs, wafer seals, cellophane tape or permanent
glue (continuous or spot) must not interfere with
recognition of the barcode, rate marking, postage
identification or required address
information. Cellophane tape is not acceptable
within the barcode clear zone. Tabs or wafer
seals placed in the barcode clear zone must
contain a paper face meeting standards for
reflectance and, if the barcode is not printed by
the mailer, the standards for water based ink.
