Postcards
Per U.S. Postal regulations, a post card cannot be smaller than 3.5” x 5” nor larger than 6.125” x 11.5”. The most common sizes for post cards are 4” x 6”, 5.5” x 8.5”, and 6” x 9”. Larger post cards work especially well for one and two color jobs as they draw greater attention to themselves without being an overwhelming block of color. A variety of card stocks are available to suit any type of printing.
