What’s the Best Poster Card Size for Direct Mail?
When it comes to getting noticed in the mailbox, the 6" x 11" postcard delivers the perfect balance of size, impact, and versatility. It is also the ideal size for EDDM visibility. Here's why it stands out as the top choice:
- The postcard size makes it easily stand out in the mailbox.
- While oversized, it's still compact enough to qualify as a postcard and avoid extra mailing costs.
- This size also complies fully with USPS EDDM guidelines, making it a hassle-free option for local outreach.
- Its generous space allows for bold visuals, detailed branding, promotional offers, and clear calls to action.
- You can also easily customize the layout by putting all visuals and key info at the front, while details can be printed at the back.
- It's a versatile choice used across industries—from real estate and retail to food services and healthcare.
- The size feels premium and professional, helping your business make a stronger impression toward potential customers.
What About the Other Postcard Sizes?
