FAQs - Invitation Envelopes By Size

Ask 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. For more information, please view the following video:

Standard Envelope Sizes: How to Find the Right Size Envelope for your Invitation

What is the most popular invitation envelope size?

Though there is no most popular wedding envelope size, the following two are certainly up there!

That being said, LCI offers an extensive variety of standard and not so standard envelope sizes to house your invitations, so the choice is yours. However, we highly recommend that whatever size you choose, that you choose it first. This way you can be sure that there is a suitable mailing envelope available for your invitations before you design them.

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 general rule of thumb is to avoid unusually shaped envelopes and to keep the weight of your invitation low. For more tips, view the following video:

What Size Wedding Invitation Will Save on Postage?

Do you sell 5x7 envelopes? I don't see the size listed.

We do not sell 5x7 envelopes, exactly. It is common for customers ask for 5x7 envelopes for 5x7 cards, but what they really need is a slightly larger 5 1/4 x 7 1/4 (A7) envelope. This size we do sell.

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 invitations, so in most cases you can choose an envelope that is just 1/8 to 1/4 inch larger than your largest card.

Do keep in mind that extra stuffed envelopes will require special attention in sealing. For more information, please view the following:

Pay Attention When Sealing Bulky Invitation Envelopes!
