A9 Envelopes (FAQs)

What size is an A9 envelope?

A9 size envelopes are 5 3/4 x 8 3/4 inches.

Is A9 a standard envelope size for invitations?

Yes, A9 is a very invitation envelope size because they fit A9, 5 1/2 x 8 1/2 cards - half of a standard 8 1/2 x 11 sheet. This makes set up, printing, and cutting easy!

Can I use A9 size envelopes for half fold cards?

Yes, a half fold is another way of saying a standard letter sized sheet folded in half to yield a 5 1/2 x 8 1/2 inch card.

Do A9 envelopes require more postage?

Based on shape and size along, A9 envelopes require just standard postage provided they are one ounce or under. Anything over an ounce, however, requires more. We recommend bringing one finished invitation ensemble to the post office to determine accurate postage.
