Tabbing of Booklets

July 23, 2010

The changes in tabbing regulations for booklets that took effect in September of 2009 continue to confuse designers and mailers.  First of all, one needs to understand what the Post Office considers to be a “booklet”.  A booklet is a letter-size piece (maximum size of 6.125 x 11.5) that consists of multiple sheets of paper that are bound together by some sort of permanent fastening (most commonly staples or saddle-stitching).  If a multi-page piece, held by a corner and shaken, does not fall apart, it is a booklet.  The bound edge on a booklet must be on the bottom or right edge, as one looks at the addressing panel.  Three tabs will be required, and the tabs must be at least 1.5” in diameter, frosted, and non-perforated.  The positioning of the tabs depends on where the closed edge is.
