Format Options
There are four basic
formats: upright, oblong, narrow, and square. Certain measurement
ratios, described below, will qualify a given folded piece as
a specific format. It is important to note that not all folding
styles can be built in all four formats.
 |

Oblong
To qualify as an oblong format, the finished width of
the piece must be more than 3/4 inch greater than the
finished height. Some common oblong dimensions are 6"
x 4" or 8" x 5". An example of how to
communicate format to the printer would be: "4-page
Standard, oblong format," followed by the finished
dimensions.
There are
special considerations for an oblong format piece—check
with the printer or print finisher about the minimum
height capabilities of the folding machinery.

|
Narrow
To qualify as a narrow format, the finished height must
be at least twice the finished width. Some common narrow
dimensions are 4" x 8" or 3" x 9".
An example of how to communicate format to the printer
would be: "4-page Standard, narrow format,"
followed by the finished dimensions.
There are
special considerations for an narrow format piece—check
with the printer or print finisher about the minimum
width capabilities of the folding machinery.

Square
To qualify as a square format, the difference between
the finished height and finished width cannot be more
than (+/-) 3/4 inch. Some common square dimensions are
6" x 6" or 6" x 5 1/2". An example
of how to properly specify a square format fold to the
printer would be: "4-page Standard, square format,"
followed by the finished dimensions.
There are
special considerations for a square format piece—if
planning a piece that will go through the mail, please
note that square mail will require extra postage.
