Can you mail a 5x7 postcard

Yes, you can mail a 5x7 postcard, but it's not a standard postcard size. In the United States, the standard postcard size is 3.5 x 5.5 inches, and that's what the US Postal Service (USPS) recommends for postcards.

However, you can still mail a 5x7 postcard, but it will be considered a letter, not a postcard. Here are a few things to keep in mind:

  1. Size and shape: A 5x7 postcard is larger than a standard postcard, so it may not fit in a standard postcard envelope. You'll need to use a larger envelope, such as a #10 envelope or a flat rate envelope.
  2. Weight: A 5x7 postcard is heavier than a standard postcard, so it may cost more to mail. The USPS charges by weight, so a larger postcard will cost more to mail than a standard postcard.
  3. Postage: You'll need to affix the correct postage to your 5x7 postcard. For a letter weighing up to 1 ounce, the current postage rate is $0.55. If your postcard weighs more than 1 ounce, you'll need to add additional postage.
  4. Delivery: Since a 5x7 postcard is considered a letter, it will be delivered like a letter, not a postcard. This means it may take longer to arrive, and it may not be delivered to a post office box.

If you still want to mail a 5x7 postcard, make sure to follow these guidelines:

Keep in mind that some countries may have different postcard sizes and regulations, so be sure to check with the destination country's postal service for specific guidelines.
