"A regular sized letter weighing less than 1 ounce will need $0.55 worth of postage. Each additional ounce will cost you $0.20. So, a 2 ounce letter would need $0.75 worth of postage. Once your letter reaches 3.5 ounces, then your item is considered a flat package and no longer follows the letter mailing rules."
