Question

What envelope size do I need for a 4.25 x 5.5 inch RSVP card?

Answer

A 4.25" x 5.5" RSVP card pairs with an A2 envelope, which measures 4.375" x 5.75". That gives about 0.125" of clearance on each side.

  • Card: 4.25" x 5.5"
  • Envelope (A2): 4.375" x 5.75"
  • Clearance: about 0.125" per side, so the card slides in and out smoothly.

That small gap is intentional - it keeps the card easy to handle without letting it rattle around inside.
