Are there children in the home? maybe two level? For children 4 feet adults Aprox 5 feet off the floor is a average leaving roughly 3 feet above the bench for jackets to hang down. Longer coats would need to be higher. Generally coat hooks are for casual jackets & coats that are not knee length. Long coats just don't work well on hooks above benches. With out looking oddly highly hung. A pic would be a great help for more ideas.
