Wrote correct measurements, wrong order for postage?

-I have a package that i am mailing out today

The measurements are 15"x 12" x 5"

I'm sending it via USPS.

I accidentally wrote it as 15"x 5" x 12"

And printed the postage and dropped it off at the post office.

Will there be any problems with this?Probably not as the overall volume will still be the same. You just got the numbers the wrong way round.
