Postcards are useful when trying to promote specific programs, courses, or events to the larger community. Postcards can be mailed in bulk via the US postal service. If mailing is not an option, postcards can also be distributed on campus. Generally produced in a landscape format, postcards are designed in the following sizes: (4”x 6”), (5”x 7”), or (5.5”x 8.5”). Depending on design layout, postcards can also be designed in a portrait format in special circumstances.
