I'm making my own invitations. I was planning to make them A7 size (approx 3x4), which I think is cute. But when I checked USPS rules, it says you can't mail things smaller than 3x5. Is that true? Is there no way to mail cards smaller than that? Will they just refuse to let me send it?
I was planning to go shopping for paper tomorrow, and had my dimensions and quantities all worked out based on the A7 size. Now I'm afraid I'll have to rework everything...
Re: Can I mail invitations smaller than 3x5?
Make your invitations 3x5. The USPS does not fuck around.
"Love is the one thing we're capable of perceiving that transcends time and space."
And smaller than that means that your guests are going to have trouble reading them.
So I'd forget about being "cute" and resize your invitations in dimensions that the USPS will deliver and that your guests can actually read. Otherwise plan for there to be very few, if any, acceptances.
