Question: Are A2 cards suitable for postcards?
Answer: Yes! Because our A2 cards meet the US Postal Service's requirements for First-Class Mail postcards, they are a great choice. At 4 1/4 x 5 1/2 inches, they are within the USPS minimum and maximum dimensions and within the minimum and maximum thickness. Since First-Class Mail postcard stamps are less expensive than letter stamps, you can enjoy the convenience of a postcard and save on postage!/p>
Question: for a standard card is 4 1/4 x 5 1/2 the size once it's folded (meaning its the size of only one side), or is that the whole paper and is it then folded in half?
Answer: The size listed is the folded size. If you are looking at the flat card, the size listed is also the final size. /p>
