We are on opposite ends of the spectrum. I have had a few bags in the past that were too long and it bugged the heck out of me. I had the issue of bags falling to the front when I wore them crossbody and I went to pick up my kids when they were tiny. Then the bag smacks the baby and knocks him or her to the ground.....ugh....that’s why I loved backpacks for such a long time.I'm 5'2 and a size 4, and find that crossbody straps are sometimes longer than I'd prefer.
If I crouch down (and I do this a lot, with a 2 year old) and the bag manages to hook under my butt or touch the ground, that's almost an immediate expulsion from my bag collection. I like the bag to hit my hip exactly.
