$1.20 Stamps for Large Envelope Letters (2 oz)

After January 24th, 2021, if you are mailing your "large envelope" wedding invitations or any other letter the post office deems as a large envelope (sometimes called "Flats") and it weighs 2 oz you will need $1.20 in postage to mail it 1st-class. Letters are considered "large envelopes" or "flats" if they measure greater than 6-1/8 inches high OR 11-1/2 inches long OR 1/4 inch thick. You can determine if your letter is a standard letter or a large envelope by using our postage calculator, but be sure to double-check the weight of your invitations with your local USPS post office.

There are no stamps with a face value for this specific rate. If you want to use stamps you'll need to combine stamps with a smaller face value to add up to $1.20 or greater.
