The height and reach relationship between the saddle and handlebars is a very personal one and there are several important questions that need to be answered in coming up with a position on the bike that works well for YOU.
Your position has to be somewhat comfortable to you or at least close enough to comfortable that you can condition yourself and train your muscles and skeleton to be comfortable.
A racer will train himself to be low and aerodynamic for efficiency and power. A commuter or bike path pleasure rider might be more upright for good vision, comfort and repeated stopping/starting. A recreational or sport rider might be somewhere in between the two.
Riders that spend many hours in the saddle such as tourists or club riders, for example, want to distribute more of the body weight on the hands, arms and shoulders to relieve some percentage of weight and pressure on the saddle. What percentage weight you carry on the saddle, the pedals and the handlebars is whatever works best for the style of riding you do, how well your body conforms to a particular position and the goals you have set for yourself.
