How many pages can a forever stamp mail

According to the United States Postal Service (USPS), a Forever Stamp can mail a standard letter weighing up to 1 ounce. This typically includes a standard-sized letter with a maximum size of 11.5 inches long, 6.125 inches high, and 0.25 inches thick.

Here are some guidelines on what you can mail with a Forever Stamp:

• Standard letters: Up to 1 ounce, 11.5 inches long, 6.125 inches high, and 0.25 inches thick
• Large envelopes (flats): Up to 13 ounces, 12 inches long, 15 inches wide, and 0.75 inches thick
• Postcards: Up to 1 ounce, 4.25 inches long, 6 inches high, and 0.016 inches thick

If your mailpiece exceeds these dimensions or weighs more than 1 ounce, you'll need to use additional postage. Here are some examples of what might require extra postage:

• Large envelopes (flats) over 13 ounces
• Letters over 1 ounce
• Packages or parcels
• Oversized or irregularly shaped mailpieces

Keep in mind that the USPS has specific rules and regulations for mailing certain items, such as packages, periodicals, and international mail. If you're unsure about the postage requirements for your mailpiece, you can consult the USPS website or visit your local post office for guidance.
