What paper thickness should I use for EDDM postcards?

For EDDM postcards, USPS sets a minimum thickness and your card size drives the practical choice. Thicker stock survives sorting and arrives looking crisp, so match the weight to how large the card is.

USPS requires a minimum thickness of 0.007", and both 14pt and 16pt clear it comfortably. As a feel reference, 14pt is like a standard business card, sturdy and professional, while 16pt is closer to a credit card, premium and substantial. With dozens of paper types and multiple finish choices available, you can pick the right weight and look for your specific EDDM size.
