4" × 6"
The default mailed postcard. Big enough for one image and one idea.
Whether this size mails at the postcard rate depends on its final caliper as well as its dimensions. We confirm the class before the paper is ordered rather than guess at it here. Exact USPS dimensions and rates are confirmed per job.
