This is definitely a "one size fits all" sort of poncho. I'm 5'4" and it came past my knees and was very wide on me and i'm 180lbs.  But it worked WONDERFULLY.  I wore it to an all day jazz festival where it rained for 5 hours straight.  It kept me dry and was large enough to cover most of my body when seated.  I wish the hood was a little more oversized but overall, it was well made and did what I expected.
