These are the four main size categories that USPS uses to classify mail and determine postage. Is your mail a postcard, letter, flat or parcel? Here's the quick answer:
(Click on the links for more detailed information.)
A postcard is a card (not an envelope) that fits ALL THREE of the following:
  • 3½ - 4¼ inches tall; and,
  • 5 - 6 inches wide; and,
  • 0.007 - 0.016 inches thick.
    For Marketing Mail (bulk mail) and Periodical Class (newspapers and magazines), postcard-size pieces are classified as letters, not postcards.
A letter is a rectangular card or envelope that fits ALL THREE of the following:
  • 3½ - 6⅛ inches tall; and,
  • 5 - 11½ inches wide; and,
  • 0.007 - ¼ inches thick
    (except at least 0.009' thick if the piece is larger than 4¼' x 6').
  • weighs no more than 3½ ounces (applies to First Class letters only).
    If your letter is an unusual size, shape or material, or have unusual content, find out if you have to pay a surcharge. For First Class mail only (including regular mail and Presorted First Class), a card that is postcard-sized is a postcard, not a letter.
A flat is a rectangular card or envelope that is larger or heavier than a letter, meeting AT LEAST ONE of the following:

A parcel is an envelope, carton, tube, or anything else that fits ANY one of the following:
