Unless your wedding invitations are a single sheet of 80 lb. cover stock in an average envelope, chances are you will need more than one first-class postage stamp on your envelopes to get them to their destination.
If you guess or assume the amount of postage required and you're wrong, all your wedding invitations will be returned to you rubber stamped "insufficient postage."
They will be returned provided you didn't skip putting a return address on your envelopes. Yes, some people have chosen to ignore the obvious and to save time or money, did not put a return addresses on their envelopes and the post office has no clue what to do with your beautiful invitations except to toss them.

In the planning stages, it is important to ask how much your invitations will cost to mail. If adding $.11 or more postage just to be able to mail square envelopes (has nothing to do with weight, but orientation limitations with the post office scanning equipment) is something that isn't in your budget, you will need to choose a different size invitation before you get to the design, proof and printing stages.
Do NOT buy all your postage until you have mailed a sample to yourself. As soon as you get your invitations, put one together with all the pieces, address it to yourself, take it into the post office and have a postal employee determine and affix the correct amount of postage for your invitation, then mail it to yourself. You can work on assembling and addressing all the invitations after you've mailed this test sample. When your sample arrives in your mailbox, you'll know the postage was correct (or not if it was returned to you with "insufficient postage" stamped on it), you'll also see how it survived its journey and what your guests will see in their mailboxes and you can make any changes necessary before you mail all the invitations. After you've done the test mailing, you can then buy your postage.
Don't guess at postage and don't take chances with your invitations. A few extra steps will ensure your guests receive their invitations.
