Why the 4” x 6” Postcard Endures
In a world saturated with digital ads, pop-ups, and emails, the 4” x 6” postcard continues to deliver results. It’s compact yet substantial, affordable yet premium, and simple yet remarkably flexible.
For more than five years, 4” x 6” postcards have been one of our most requested and most successful print products at Texas Pro Print—and for good reason.
They strike the perfect balance between visibility, usability, and return on investment.

-
Durable feel: Especially when printed on thick 16pt cardstock

Easy distribution: Handouts, mailers, counter displays, packaging inserts

They’re small enough to be convenient and large enough to be remembered.
