Standard Postcard Template Sizes and USPS Specifications<\/p>\n\n\n\n

Postcards are the most common direct mail format and the most cost-effective. The USPS defines three postcard tiers \u2014 each with different postage rates, minimum\/maximum size limits, and template requirements.<\/p>\n\n\n\n

Postcard Size Reference Table<\/h3>\n\n\n\n
Format<\/th>Minimum Size<\/th>Maximum Size<\/th>Most Popular Dimensions<\/th>Postage Class<\/th><\/tr><\/thead>

Thickness requirement:<\/strong> All postcards must be at least 0.007″ thick (approximately 14pt cardstock). Pieces thinner than this are non-machinable and will either be rejected or charged a higher rate.<\/p>\n\n\n\n

Layer<\/th>Dimension<\/th><\/tr><\/thead>
Bleed canvas<\/strong><\/td>6.25″ \u00d7 9.25″<\/td><\/tr>

Safe zone<\/strong><\/td>5.75″ \u00d7 8.75″<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Rule of thumb for any size: Add 0.125″ to each dimension for the bleed canvas. Subtract 0.125″ from each dimension for the safe zone boundary.<\/em><\/p>\n\n\n\n

It is ideal for local businesses targeting a specific neighborhood or ZIP code. The template requirements are stricter than standard postcards because EDDM pieces must qualify as “flats.”<\/p>\n\n\n\n

EDDM Size Requirements<\/h3>\n\n\n\n

To qualify as EDDM Retail, a mail piece must meet ALL of the following:<\/p>\n\n\n\n

Maximum weight: 3.3 oz<\/p>\n\n\n\n

At least one dimension must exceed 6.125″ OR 11.5″ (this is what makes it a “flat”)<\/p>\n\n\n\n

No dimension may exceed 12″ \u00d7 15″<\/p>\n\n\n\n

Minimum thickness: 0.007″ (14pt cardstock minimum \u2014 same as standard postcards)<\/p>\n\n\n\n

Maximum thickness: 0.75″<\/p>\n\n\n\n
