Need to post your wedding invitations, R.S.V.P cards, save the date and other wedding cards? Do you know when, and how to send? Do you have to pay any extra charges? What is the standard weight and size? Do 5x7 envelopes require extra postage? United States postal service (USPS) has answer to all your important questions. Before buying stamps for your wedding invitation postage, you need to know a few important things about USPS policies.

Do 5x7 Envelopes Require Extra Postage?

In April 2016 USPS has decreased the prices and current rates for 1st class mail are as follows:

A rectangular 5x7 envelope is the standard size that is used in the United States for mailing letters and invitations, so if your envelopes are within the weight range of 1oz, then you just need to pay $.47 for each one, without extra charge. Note that the USPS even offers wedding-themed stamps (1st class 1oz ) at 47 cent!

Posting charges are not only limited to the size but also weight of the mailings. Even if you have used a 5x7 envelope but it is heavy (because along with the wedding invitation you have also inserted the reception card and R.S.V.P card, etc.), you will have to pay extra charges. Layered or folded invitations will require 68 cent per postage stamp or more. Envelope thickness standard should be no more than ¼ inches. Using thick envelopes can also lead to application of nonmachinable charges.  

Rigid, squared cards (or any other shape besides rectangle) are some of the characteristics which may result in extra postage i.e. at least 21 cents extra per card. These extra charges are referred to as nonmachinable charges, because deviation from the standard requirements may block the usual postal equipment and automation process (in others words, these extra charges are due to hand stamping). 

To find out what exact amount you will need to pay, go to the nearest post office and ask them to weigh your mailing items.

Postage calculator is very convenient to use; all you have to do is, enter the dimensions of your invitation and it will tell you about your mailing cost and whether an extra postage is required or not.

What People Have to Say?

Do 5x7 envelopes require extra postage? A lady said:

“If you are mailing wedding invitations in 5x7 envelope then there is no need to paste extra stamp unless or until it is heavier than the standard weight.”

At another forum, one of our brides shared:

“Though I used 5x7 envelope, I pasted 68 cents stamps because my mails were heavier than the standard as I also inserted the R.S.V.P and detail cards.”

The number of cards doesn’t matter, if your 5x7 envelope is under the recommended weight limits:

“My save the date card dimension was 5 1/2 X 7 ½. It was two layered, including 4 business cards enclosed in a small envelope. Postage was 47 cents only because total weight was one ounce”.
