You want 7' if there is cows around. You best have it tied down well if there are cows or pigs. They learn if they bump it, corn will come out. Hanging feeder is best. They hit legs, it won't make corn come out. I like to pull them up from a tree limb. I put wench on tree, cable goes up to limb with pulley. My son in law hunts where they have black bears. Hanging feeders only way to keep a bear from jacking feeder up.
