I'm 6,0 and 197 lbs, waist is between 34 and 36,whats my size? L?

The waistband is very forgiving on these pants. I am your same build and if stretch out the waist I could fit both arms in easily whilst wearing them. The large would fit perfect in my opinion if your looking for a somewhat tight look in the leg area go for a med I'm sure they will stretch to fit the waist. But for a relaxed fit in the leg stay with the large.

what my size if im 5,9 120lbs my mom wont reply?

I don’t understand about your mom but my son is 6’3 and 145 pounds and he got the medium.They work well with boots or high tops really well.

Does medium fit a 5’4 guy 145 lbs?

I would do a large or xl so it could fit loose like the style fits
