Large Mailpieces, Envelopes, & Small Packages Between 22 and 30 inches long: add $4.00. More than 30 inches long: add $7.00. More than 2 cubic feet (3,456 cubic inches): add $15.00.

That said, there are often cases where a large envelope weighs more than just one ounce. A letter covered by First-Class stamps can be up to three ounces, and if your letter weighs more than one ounce, you'll need to pay for the “Additional Ounce” postage to cover each additional ounce up to three ounces total.

For any domestic mail piece that weighs more than one ounce, you must include additional postage along with your Forever Stamp to ensure USPS delivery. Also, you may purchase higher denomination postage stamps for heavier postage at the Post Office™. Avoid placing two Forever Stamps on a mail piece for heavier mail.
