It depends, I have one stand in a small tree out in a pasture that's only 7' off the ground. I have one stand where I have a creek behind me and I'm 30-35'high but in front and to my left and right 20yds out it goes up hill and I'm only 10' above the ground but from the base of the tree I'm 20' off the ground, weird but very productive area.

My other stands are 20-25'.
