Maximum size for Invitations w/out extra postage cost

It also goes by the weight. Go to the Post office and ask them to slide it through their "fake slot" if it fits it will ship, then you just have to worry about the weight

Oh my envel;ope fit & it was 5 1/4 by 7 1/2.

And my envelope fit through their fake slot it was 5 1/4 by 7 1/2. It barely made it

Haha sorry it didnt post the first time..and now all of a sudden it appears lol!

I hope this helps? I second what Ana said they go by weight.

5 1/2 X 7 1/2 is a good size. Up to 1 oz is 44 cents, 2 oz is 61 cents and 3 oz is 78 cents. My save the dates were 5 1/2 X 7 1/2, they were 2 layers and I included a small envelope with 4 business cards in them. They were just under 1 oz. so postage was only 44 cents.

Square envelopes are extra, no matter what the size. They charge an extra $0.20 for square, since it's considered non-machinable.

A 5.5x7.5 envelope will not require extra postage because of the size.

Depending on how many inserts you have though, it might need extra postage to cover the weight.

ALSO, if the envelope is especially thick (post office can measure for you) it will also require extra postage.

Square invitations will automatically require extra postage as well.

Be careful with your RSVP cards, my RSVP cards and envelopes were 3 1/2 x 4 1/4 and because of their smaller size they ended up costing more than the invite.

Yeah anything too small, too big or too heavy wont go through the machines. Having the machines do most of the work has kept regular postage lower. Gotta pay someone to do the work if the machine cant. Im expecting my 5X7 invites to cost at least 61 cents. But Im doing post card RSVPs to offset the cost.

USPS regulation for First Class Mailing:

at least 3-1/2 x 5 and .007 thick but no more than

6-1/8 x 11-1/2 and .25 thick

Does anyone know how much the postal cost will be for a 5X7 invite and an enclosure card with 220 lb paper each? I know I can go to the post office but if anyone knows, it'll help Thanks in advance.
