What is the size of a standard wedding invitation envelope?

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.
