Allowable Label Size

What is the smallest pre-paid printed label size that USPS allows?

about 4"x6" (Prepaid?- why?? until buyer buys you have no idea unless you are using USPS Flat Rate, and even then..you don't want to 'buy' it until you have a 'ship to' address (not counting prepaid flat rate boxes/envelopes)

TY for your response.

On some smaller packages I've been printing postage labels at 70% of full-size with no problem. They've been successfully scanned at the PO and ultimately delivered.

In particular, this current package I'm inquiring about is 4"x4"x 4".  Can I "drape" the label over the side if larger or does it have to be only on one side?

TY again.....

You can "drape"  it over the side.  I see local PO clerks do it all the time.

There is a minimum size for International packages stated because the label has to be a certain size to accommodate the customs information. I had a 4 X 4 X 4 box. I shipped the box in a large plastic Shipping Envelope and it was fine.
