The Standard RSVP Card and Envelope Size

The most common RSVP card and envelope size is a 5 x 7 inch A7 envelope with a corresponding 3.5 x 5 inch (A7) RSVP card. This size is versatile and popular because it's not too large to be easily lost or too small to be hemmed in by smaller envelopes. It'sroomy enough for guests to write their response yet compact enough to be elegant.

When designing your invitations, remember that the size of the envelope can impact the design. A larger envelope gives you more space to play with your design, but it's essential to ensure that the design isn't too crowded. Conversely, with a smaller envelope, you might want to use simple, elegant designs to allow the invitation to shine.
