To hem or not to hem?

Hey y'all, I'm noticing that a lot of the shirts I buy feel like they're comically oversized at times. Specifically, the shirts feel like they're too long for me, which is more pronounced with shorts <= 7". I think it might be related to having longer legs and a shorter torso... here's an example. The dashed red line indicates where I would hem to. So, to hem or not to hem? Thanks!
