New Regulations For Folded Self-Mailers

January 5, 2013

There will be new regulations for folded self-mailers (FSM) and other unenveloped mail pieces beginning January 5, 2013. These new rules do not apply to cards, envelopes, booklet style letters or mailpieces designed to carry discs.

You should make sure to use up any old stock and make design changes now before the deadline sneaks up on you!  Review the regulations and compare with your existing mailpieces to insure they meet requirements. Don’t get stuck with unmailable pieces or higher postage rates.

  • Length:  Minimum 5” and maximum 10 ½”
  • Height:  Minimum 3 ½” and maximum 6”
  • Thickness:  Minimum 0.007” (0.009” if the height exceeds 4 ¼” or the length exceeds 6”)  Maximum thickness is ¼”
  • Weight:  Maximum 3 ounces
  • Rectangular, with four square corners and parallel opposite sides
  • Aspect Ratio (length divided by height) 1.3 to 2.5 inclusive

The regulations include information on “panels” and approved folding and panel configurations. Sealing options are also addressed – including glue lines, spot glue and tabbing options. There are also options for other design elements such as die cuts, perforations, loose enclosures and attachments.

More information regarding the revised regulations can be found on the RIBBS website:
