Depends on your set up and where you can have some cover as well as have a good opportunity for a shot. It will depend on the terrain you hunt...I have placed hang on stands from 10' to 35' b/c of the terrain and surroundings...There is not a set height to put it, put it where you are comfortable shooting from as well as feel safe....
