One of the first decisions businesses face when planning\u00a0an Every\u00a0Door Direct Mail (EDDM) campaign is choosing the right postcard size.<\/span>\u00a0<\/span><\/p>

The United States Postal Service (USPS) reports that over 57 billion pieces<\/a> of marketing mail are delivered every year, and postcards remain the most frequently used direct mail format, with 66% of marketers<\/a> choosing them.<\/p>

While EDDM allows flexibility, most campaign postcards come with specific sizes in mind. The most popular EDDM postcard sizes are 6.5\" \u00d7 9.0\", 6.5\" \u00d7 8.0\", and 6.5\" \u00d7 12.0\". These standard sizes are\u00a0\u00a0 practical to design, efficient to print, and easy to mail under USPS rules.<\/span>\u00a0<\/span><\/p>

\u00a0This article breaks down the three most popular EDDM postcard<\/a> sizes, why they work, and how USPS requirements shape your options.<\/span>\u00a0<\/span><\/p>\n<\/div>

6.5\" \u00d7 9.0\"\u00a0<\/h3>

This is one of the\u00a0most commonly used\u00a0EDDM postcard sizes because it sits comfortably\u00a0within\u00a0USPS\u00a0requirements without feeling oversized. It provides enough space to communicate a clear message while keeping production costs manageable.<\/span>\u00a0<\/span><\/p>\n<\/div>

Businesses often choose this size because\u00a0it\u2019s\u00a0easy to design and\u00a0visible\u00a0in a crowded mailbox.<\/span>\u00a0<\/span><\/p>

This size is commonly chosen when:<\/span>\u00a0<\/span><\/p>

  • The message is simple and focused on one main offer<\/span><\/li>

    6.5\" \u00d7 8.0\"\u00a0<\/h3>

    This slightly compact format is still EDDM-compliant, making it a popular option for cost-conscious campaigns.\u00a0<\/span>\u00a0<\/span><\/p>

    This affordable\u00a0option\u00a0offers slightly less space than the standard size, with most of its designs, relying on strong headlines and minimal copy rather than detailed layouts.<\/span>\u00a0<\/span><\/p>

    This size is commonly chosen when:\u00a0<\/strong><\/p>

    • The primary message is short and direct<\/span><\/li>
    • The campaign is recurring or time-sensitive<\/span><\/li>
    • The goal is to reach customers rather than visual complexity<\/span><\/li><\/ul>\n<\/div>
      \n

      6.5\" \u00d7 12.0\"\u00a0<\/h3>

      The 6.5\" \u00d7 12.0\" size offers more vertical space without crossing into oversized territory. That extra room makes it easier to organize images, headlines, and support information in a more balanced way.<\/span>\u00a0<\/span><\/p>

      This size is often used when campaigns need more flexibility in layout while still staying practical for printing and handling.<\/span>\u00a0<\/span><\/p>

      This size is commonly chosen when:<\/span>\u00a0<\/span><\/p>

      • Campaign provides multiple offers or visuals need room<\/span><\/li>
      • The design requires clearer hierarchy<\/span><\/li>
      • The campaign targets competitive neighborhoods<\/span><\/li><\/ul>\n<\/div>

        \nWhy These Sizes? \n<\/h2>
        \nThese postcard sizes often solve the most common EDDM challenges at once: visibility, cost, and ease of execution. Each\u00a0option\u00a0is large enough to stand out from standard mail, simple enough to design without overthinking layouts, and efficient to produce at scale.<\/span>\u00a0<\/span>\n\nOver time, USPS requirements have reinforced these patterns by rewarding sizes that are clearly larger than standard mail but still easy to process and distribute.<\/span>\u00a0<\/span>\n\n
