r/FedEx on Reddit: Question about package weights
May 23, 2024 -

Hello, I am going to ship packages soon with FedEx. I got boxes from your stores however the weight limits on them seem unclear. The boxes themselves state a 30 pound limit but every time Ive shipped something with FedEx, they weigh it there. Am I correct in assuming that as long as the box with its contents in it is below 150 pounds when it gets weighed at the store they will still ship my package or do I have to downsize? A speedy answer would be nice.

TLDR: What is the weight limit for packages, if its under 150 pounds Im good right?
