As they say, “A penny saved is a penny earned.”
Because the postage rate for a flat is considerably higher than that of a letter, taking size and postal regulations into account before you design a folded self mailer can save not just one penny… but many.
What’s a folded self-mailer? By definition it is a mailpiece “formed of two or more panels created when a single or multiple unbound sheets of paper are folded together and sealed.”
Per USPS Regulations, to be eligible for mailing at the letter rate as of January 5, 2013 a folded self-mailer must be:
- A minimum of 3.5 inches high x 5 inches long
- A maximum of 6 inches high x 10.5 inches long
- Rectangular (must meet proper spec ratio of length divided by height)
- Minimum spec ratio of 1.3
- Maximum spec ratio of 2.5
Thickness and weight also matters, but that depends more on the stock you choose than it does on design, so we will save that for another day.
The Bottom Line? If you are producing a folded self-mailer and plan your crop lines and folds strategically, you can take advantage of letter rate postage.
A quick trim will take an 11 x 17” sheet down to 10.5 x 17”. The right fold will take it down to 10-1/2” x 5.66.” If you forget the trim, or do an uneven fold that brings the height dimension up your piece will go as a flat.
