If worried about the size of your postcard, a standard postcard is measured 4 by 6 inches. Postcards can actually be any size so they can be different in any country.
The standard size for a postcard is 4x6" and the biggest size is 6x11". I am not sure if there are postcards smaller than the 4x6".
Creating your own photo postcards will cost anywhere from $.10-$.60 each depending on if you are getting standard size or oversized ones. It also depends on the quanity you are ordering. Standard size and a bulk order of 500 or more would be the most economical method. Mailing it domestically through USPS is a $.27 each for a standard postcard and $.42 each for an oversize one.
The postage for a postcard is valued at $0.33 as of 2014. This can vary depending on the size of the postcard and may change as the Postal Service changes its rates.
The layout of a postcard must follow specific USPS guidelines. These guidelines include size, zones that designate where the sender's address goes, and proper layout.
The standard postcard size ranges from 3.5" x 5" to 6.125" x 11.5". Any sizes that will not fit within this range will not be processed by the Post Office.
