FAQs - Invitation Envelopes By SizeAsk Us A Question
How do I determine the proper envelope size for my invitations?
It is a good rule of thumb to choose an envelope that is 1/8 to 1/4 inch larger than your invitation card. This will allow your invitation to fit in your envelope easily without allowing too much wiggle room.
What is the most popular invitation envelope size?
There is no most popular or best wedding envelope size. People choose many different sizes of wedding envelopes according to preference and what they want their final invitation design to look like. If we had to say which size envelope is the most popular we offer that would be our (A7)5x7 Envelopes, more commonly known as A7 envelopes that measure 5 1/4 x 7 1/4. LCI offers an extensive variety of standard and not so standard envelope sizes to house your invitations, so the sky is the limit! However, we highly recommend that whatever size envelope you choose, that you choose it first, then design your card after! This way you can be sure that there is a suitable mailing envelope available for your invitations right from the start.
What size envelope is the most economical to mail?
The price of postage varies with the shape and size of your envelope as well as the weight of invitation ensemble. A good, general rule of thumb is to avoid unusually shaped envelopes such as squares and to keep the weight of your invitation ensemble to a minimum. For more tips, view the following video: What Size Wedding Invitation Will Save on Postage?
If my invitation is very thick do I need a larger envelope?
The more you put into an invitation envelope, the more the sides bow out, and the less accommodating the envelope becomes. Envelopes are made to accommodate all of the extra cards and embellishments that are often included in wedding invitations, so in most cases you can choose an envelope that is just 1/8 to 1/4 inch larger than your largest card; but do keep in mind that extra stuffed or extra thick envelopes will require special attention in sealing.

Response cards and envelopes are most commonly A1 size
My wedding invitation is printed on A5 paper. I was told that I need a C5 enevelope for this. Plus I also have a response card that needs an envelopes. I really like your double wedding envelopes. Do you have the size I need available?
The A5 size corresponds to a different standard than what is common in the U.S. I believe you are referring to an invitation card size of 210 x 148 millimeters (8.3 x 5.8 inches). Unfortunately we do not carry any Double Wedding Envelopes sized to accommodate this card, nor do we carry any C5 envelopes which measure 162 x 229 millimeters (6 3/8 x 9 inches). To accommodate your card, we do offer an A10 6 x 9 1/2 envelope (152.4 x 241.3 millimeters). But you may find it to be wider than ideal. Also, keep in mind that this is a single envelope, not a double envelope.
I would like to make an invitation that fits into an A10 envelope, but I'm confused; do you have in stock the card that would fit inside, or does that have to be specially cut?
A10 invitation envelope and card sizes are less common than A9. Although we carry a limited selection of A10 envelopes, we do not carry any A10 cards (5 7/8 x 9 1/4). Custom size cutting is not an advertised service available through our web site, but we can arrange for cards to be cut to a certain size specified by you.
I will have wedding invites made which are 5 x 7 inches. I would like to order double (lined) envelope sets. Which do you recommend?
The best double envelope to fit your card is our Jumbo size where the inner measures 5 5/16 x 7 5/8 and the outer measures 5 7/16 x 7 7/8. To find these, just go to our Double Wedding Envelopes page. Under Select Size, choose Inner Envelope 5 5/16 x 7 5/8 Outer Envelope 5 7/16 x 7 7/8.
