Postcard Size Guide

Choose postcard size by working backward from the message, the audience, and the mailing method. A larger card can create more visual impact and copy space, while a smaller card can encourage a tighter, simpler offer.

4 × 6

A compact format suited to one main visual, one offer, and a concise call to action. Keep type comfortably readable and protect the address and postage area required by the mailing plan.

5 × 7

A balanced format with room for a stronger before-and-after story, service list, event details, or a simple map while still encouraging disciplined copy.

6 × 9

A high-visibility format with space for a more substantial offer, proof points, and a second call to action. It can work well for local campaigns when the additional room improves clarity rather than adding clutter.

6.5 × 9

Often considered for larger direct-mail formats and route-based programs. Eligibility, postage class, aspect ratio, thickness, addressing, and route requirements must be verified for the specific mailing method.

Before choosing

• Confirm the mailing program and current postal eligibility.
• Reserve the correct address, indicia, and barcode areas.
• Choose stock and coating that fit the writing or handling need.
• Verify finished size, quantity, postage, route or list, proof, and schedule.
