How much postage do you need to mail a 5 X 5 inch envelope in the US?

Answer 1

I mailed 5 x 5 inch Christmas cards . most were returned to me , rubberbanded together , saying insufficient postage. I went to my postal annex and they said because they were square they required an extra 15 cent stamp. i asked why only some were returned and they said sometimes the postmaster will let them thru or possibly charge the recipient. Considering the size of regular cards is much larger I feel this is not fair.

Answer 2

To qualify for the First Class postage price for letters, a piece must be:

• Rectangular and have angular (90 degree) corners.
• At least 3- inches high x 5 inches long x .007 inch thick
• No more than 6-1/8 inches high x 11- inches long x 1/4 inch thick.
• Square letters (such as the popular "musical" greeting cards) are mailable, but do not fit well into mail processing equipment. Therefore, square mail-pieces are subject to a $0.20, non-machinable surcharge because their length/width ratio is less than 1:3.

Example 1:A slightly flexible greeting card that measures 6-1/8" long x 6-1/8" high x 1/4" thick and weighs 1.5 ounces. Although it falls within letter-size standards, it does not meet the aspect ratio criterion (it is square and therefore has an aspect ratio of less than 1:3). The mail-piece is classified as a non machinable letter and the customer pays the 2-oz. letter price ($0.59) plus the $0.20 non machinable surcharge, for a total of $0.79.

Example 2:A uniformly thick, slightly flexible musical greeting card that measures 6-1/4" long x 6-1/4" high x 1/4" thick and weighs 2 oz. It exceeds the maximum letter height of 6-1/8", but it meets the rectangular, uniform thickness, and flexibility criteria for a flat letter. The mail-piece is classified as a flat and the customer pays the 2-oz. flat price of $1.00.(see Large Envelopes - Qualifications & Prices for additional information)
