A2 Card - Standard RSVP Post Card Size - For Saving a Little Money
An economical, eco-friendly, and increasingly popular choice, many are choosing to use RSVP post cards. This eliminates the mailing envelope and reduces postage costs.
What size is a post card? The USPS has the following post card size requirements:
Rectangular card, at least:
- 3 1/2 inches tall
- 5 inches long
- 0.007 inches thick
Postcards can be no more than:
- 4 1/4 inches tall
- 6 inches long
- 0.016 inches thick
Measuring 4 1/4 x 5 1/2 inches, A2 cards are a standard post card size and an easy choice for wedding rsvp postcards.
However, any card that fits within these post card size requirements can be mailed without an envelope and with a single, economical post card stamp.
