  • Rectangular
  • At least 3 ½ high x 5 inches long x .007 inches thick

Flats (Nonletters)

The Postal Service uses the words “flats” and “nonletters” to refer to large envelopes, newsletters, and magazines. The words are interchangeable. Whatever you call them the flats must:

    • Have one dimension that is greater than 6 1/8 inches high or 11 ½ inches long or ¼ inch thick
