A 6 x 11 postcard is the largest standard postcard size available for direct mail marketing campaigns. They are also the largest postcard mailing size that qualifies for letter-sized postage rates according to the USPS guidelines making them affordable and extremely effective marketing pieces.

6 x 11 postcards are EDDM (Every Door Direct Mail) eligible and offer a large canvas to deliver your message in a way that can’t be missed.

Because 6 x 11 postcards are so large, they provide you with the opportunity to include a wide range of design elements and images. Plus, the powerful large postcard size stands out from any other mail piece in the average mailbox.

When designing your 6x11 postcard, you first need to determine the purpose of your marketing campaign and define your target audience. This will help you create a design that aligns with your message and appeals to your specific audience. After you have determined these, you need to gather high-quality images to use, choose a color palette that is on brand, create an intriguing call to action, and then take advantage of a 6 x 11 postcard template.
