4.25 x 11 – Postcards

The Postal Service has increased the maximum size for a commercial presorted or automation First-Class Mail (FCM) postcard from 4.25 inches high by 6 inches long to 6 inches high by 9 inches long. This means that businesses can now create larger postcards that can accommodate more information or graphics, making them more visually appealing and effective for advertising. Additionally, the larger size can help postcards stand out in the mail and catch the attention of recipients. This change is part of the Postal Service’s efforts to provide greater flexibility and options for businesses to use direct mail as a marketing tool.
