For me, getting the right size meant fewer shipping mistakes and less stress.
How I Check If My Documents Fit
Before buying, I always measure the papers I plan to send. I make sure they are standard letter size or smaller. If I have multiple sheets, I check that they do not create too much thickness. My rule is simple: if the contents feel too bulky, I switch to a different UPS packaging option.

- The size of the documents
- How many pages I need to send
