Question
Invitation Envelope Size Guide
Answer
Invitation envelopes are the A series. They use a thicker, more formal stock than everyday commercial envelopes and have side seams with a clean back panel, which makes them ideal for cards, invitations, and announcements.
| Size | Dimensions (inches) |
| A1 | 3 5/8 x 5 1/8 |
| A2 | 4 3/8 x 5 3/4 |
| A6 | 4 3/4 x 6 1/2 |
| A7 | 5 1/4 x 7 1/4 |
| A8 | 5 1/2 x 8 1/8 |
| A9 | 5 3/4 x 8 3/4 |
| A10 | 6 x 9 1/2 |
- The flap sits on the longer side of the envelope.
- As a rule of thumb, pick the A size about 1/4 inch larger than your card so it slides in and out easily.
