Size Matters in Direct Mail
Choosing the right postcard size is one of the most critical decisions in your marketing campaign. The size doesn't just determine how much info you can fit; it also determines your postage cost, your "stickiness" in the mailbox, and the perception of your brand.
The Standard 4" x 6" Postcard
This is the classic postcard dimension. It is cost-effective and qualifies for the "Postcard Rate" (which is cheaper than a letter). It's perfect for thank-you notes, appointment reminders, and quick announcements.
Efficiency: The 4x6 is the workhorse of the industry, offering the lowest entry point for direct mail.
The Large 6" x 9" Postcard
The 6x9 is our most popular size for general marketing. It is large enough to stand out from regular bills and letters but still fits comfortably in standard mailboxes. It provides ample space for high-quality images and itemized service lists.
The Jumbo 6" x 11" Postcard
If you want to absolutely dominate the mailbox, the 6x11 is your winner. This is the largest size allowed at standard letter rates. It is impossible to ignore. Real estate agents and home service providers love this size because it feels "premium" and offers a huge canvas for luxury branding.

Design Considerations per Size
When designing for a 4x6, keep it simple. Large text, one offer. When moving up to a 6x11, you can afford to use multiple images and even include a sidebar with "Frequently Asked Questions" or customer testimonials.
