What paper weight and finish do you recommend for postcards that will be mailed through USPS?

For postcards that travel through USPS, use a sturdy cover stock so the card survives sorting and handling. A common, reliable choice is 14pt gloss cover.

• Recommended stock: 14pt gloss cover, rigid enough to protect your design in the mail.
• Mailing fit: it stays within standard USPS mailing requirements for postcards.
• Confirm sizing: check the available stock and size options on the product page or with support for your specific mailing.

A firm cover stock keeps corners and edges crisp through automated postal equipment, so your mailer arrives looking clean.
