A Guide to Standard Postcard Sizes for Mailing
Direct mail postcards remain one of the most reliable ways to drive local consumer traffic. However, sizing your postcard correctly is the most important financial decision of your entire campaign. Choosing an arbitrary dimension can accidentally bump your mailer into a significantly higher USPS postage bracket, destroying your marketing budget.
Understanding the Standard Formats
The post office has strict size categories that dictate exactly how much you will pay per piece.
- The Economy Format: The classic 4×6 inch postcard is the cheapest to mail. It qualifies for the lowest tier of first-class postcard postage, making it perfect for massive, high-volume blasts.
- The High-Visibility Format: The 5×7 inch postcard stands out significantly more in a crowded mailbox, offering more room for graphics, but it requires standard letter postage pricing.
