Standard & Bestseller Postcards

The most popular sizes for EDDM campaigns are the 4.25″ × 11″ and 6.25″ × 9″. These formats are cost-effective and help businesses save money while still meeting USPS requirements. They are great for getting your message out without breaking the bank.

Medium to large postcards

If you want to include more details or visuals, consider these sizes:

  • 6″ × 10.5″
  • 6″ × 11″
  • 6″ × 12″

These larger postcards give you more space to work with and are perfect for local advertising. They are more visible and can stick around longer, but keep in mind they do cost more to print.

Jumbo & oversized postcards

The largest sizes offer a lot of space but are often folded or bundled with other mail:

  • 8.5” × 11”
  • 12” × 15”

While these oversized postcards are sure to stand out, they might not be the best choice for every budget. Make sure to consider the higher printing costs and how they will be handled.

Mailer formats and restrictions

The USPS has clear size and shape requirements for EDDM mailpieces. The format you choose affects your postage rates and whether your mail gets delivered. It’s important to know these formats to comply with USPS standards and ensure smooth processing.

For your mailpieces, make sure they are either rectangular or square shaped. This means they should have either four square corners or rounded corners that are not more than 0.125 inches. Triangular or circular shapes are not accepted by the USPS. Following these guidelines will help your mailing campaigns run more smoothly.

Thickness of mailpieces

The USPS has specific thickness requirements for EDDM mailpieces. Following these guidelines helps with mail processing and delivery.

  • Minimum thickness: Must be more than 0.25 inches.
  • Maximum thickness: Must not be more than 0.75 inches.

Sticking to these thickness standards is important for keeping your mail safe during transit. It also affects how you design and print your mailpieces. By meeting these thickness requirements, you’ll help ensure smooth processing and delivery, which are key for successful direct mail marketing.

Printing and paper thickness

The thickness of your mailpieces depends on a few things. This includes the type of paper you choose, any extras like coupons, and design choices like folded or multi-layered pieces. To qualify as EDDM, your mailpiece must be flat.

The USPS will not accept items that aren't flat. Also, avoid attaching any cards, as this could lead to the need for reprinting. Extra attachments can get stuck in USPS machines and cause problems.
