For me, it depends on the terrain and where the deer will be coming in. Like, if im on level ground I might not be even 10ft high. I get up near 20ft on hillsides where deer can come out above me and anything lower could put me almost eye level with the deer. I get really high when Im rifle hunting though, usually because its later in the year and the cover is fading away. Plus the shot angle isnt as critical as is with my bow. I never get too high though because I might shoot my foot off or fall out of my stand!
