Does FedEx care about a .25 or .50 inch discrepancy in box size?
Stick with what's on the box. The dimensions are for calculating from dim weight/max size (for the most part). You won't notice a difference unless for whatever reason the round up puts you in a minimum rate due to dimensions. More on reddit.com

r/FedEx on Reddit: is this FedEx box considered a Medium box or large? 20x20x12
March 6, 2026 -

I need to ship an item but the box doesn’t say if it falls under Fedex Medium Box, or Large box. The measurement is 20”x20”x12” (see attached picture).

I am purchasing the label online when I select FedEx Medium Box it’s $22.75 for the 2 days shipping but when I enter the measurement manually as custom entry 20x20x12 the price jumps to $126.32 for the 2-days shipping. Even when I select FedEx extra large box it’s only $39.40

Why such a jump in price? And how do I know if my 20x20x12 is a small medium box or large?
