What You Need To Know About First Class Mail Postage
A standard First Class Mail envelope measures between 5” and 11.5” in length, between 3.5″ and 6.125” in height and between .007” and 0.25” in thickness with a maximum weight of up to 3.5 oz.
Postage for your First Class Mail wedding invitation is determined by how much the envelope weighs. You get a 1% metered mail discount if you use online postage with Stamps.com.

Extra Fee for Square and Odd Shaped Wedding Invitations
Wedding invitations (and even holiday greeting cards) may not always comply with the USPS standards for First Class Mail. If your custom invites are square, odd-shaped, or have non-standard closures like clamps or strings, the USPS will charge a $0.22 surcharge per mail piece. The additional surcharge fee can add up quickly if you are sending invitations to a large group of guests. Often times, square shaped wedding and greeting cards are discounted, but if you don’t want to pay the additional surcharge fee, stick to the standard envelope size for First Class Mail!

When using Priority Mail International, should I ship Flat Rate or by weight?
Flat Rate Envelopes are ideal for documents or small, dense items weighing 4 lbs or less, as they offer a single price based on the destination country. For items between 4 lbs and 70 lbs, or those that don't fit into the Flat Rate Envelopes, you'll need to ship by weight using your own packaging. It’s more affordable to use Flat Rate boxes if your item is under 20 lbs.
