Wedding invitation envelopes come in a wide range of sizes. We recommend A6 for wedding invitations. However, all the other sizes work just as well. Most wedding invitation envelopes are announcement style envelopes – these have a square verses pointy flap. In the chart below are the sizes of announcement envelopes.
| Envelope Size | Envelope Dimension | Wedding Invitation Dimension |
|---|---|---|
| A2 | 4.375″ x 5.75″ | 4.25″ x 5.5″ |
| A6 | 4.75″ x 6.5″ | 4.625″ x 6.25″ |
| A7 | 5.25″ x 7.25″ | 5″ x 7″ |
| A8 | 5.5″ x 8.125″ | 5.25″ x 7.75″ |
| A9 | 5.75″ x 8.875″ | 5.5″ x 8.625″ |
| A10 | 6″ x 9.5″ | 5.75″ x 9.25″ |
