How high over the net should I hit the tennis ball?
Players in a singles match, try to get the ball about 4 to 6 feet above the net, this requires less power and helps land the ball deep in the court near the baseline. the reason they like to land it there is, because, it prevents the player from striking the ball for a winning shot. The shots that land deep tend to be put in play. The shot that lands short tend to be scoring opportunities.
