Below, we’ve listed several common postcard sizes. The size you end up with will depend on your budget and your message. Keep in mind that the smaller sizes offer more affordable postage, while the larger sizes are more likely to be noticed in a stack of mail.

4″ x 6″  4.25″ x 6″  5″ x 7″
 5.5″ x 8.5″ 6″ x 9″  5″ x 11″ 

It’s important to note that 4.25″ x 6″ is the largest size that still falls within first class postcard postage rates, and all other sizes will be charged at higher postal rates.
