To check how far away you want to stand from the ball, there's a neat and easy drill for you. When you're addressed comfortably, take your left hand off your grip and spread your 4 fingers. This 4 finger spread should then fit between your right hand and leg. (see photo). This way you can be certain you're not too close or too far away. Most amateurs tend to stand way too far away which will cause faulty balance and a poor swing. The 4 fingers will set you right every time, with every club and it's so easy to do.
