Card and Envelope Size Guide
–A new size guide is coming soon!–
*A note on postcards: A 5 by 3.5 inch postcard is the minimum that can be mailed. A2 cards can also be used as postcards.
In addition to the size, postcards must be 0.007 inches thick meet requirements for mailing.
*A note on square envelopes: Square envelopes of any size require additional postage. I recommend budgeting for the cost before placing you order.
