So we have a vertical tester and decided to roll it out to the courts. The one depicted is 10 foot at the top rung. 8 foot at the bottom. He did a test jump without a racket up to 9‘ feet 6 inches”. From prior posts of mine I’ve made it clear that he’s hitting a pretty good twist serve but he’s not hitting the booming flat serve yet. He hit a test flat (ish) serve depicted below and his contact height with a racket is a solid foot below where he can reach without a racket. What to make from this observation?

tennisdad you can PM or email me for more info because I can't post a lot about this online, but be very careful about prioritizing contact height. You are better off focusing on the hand path and racquet path going up and through the ball and then once you are happy with that have the kid challenge himself with the toss (I love that phrase stolen from Pat Dougherty) so the throwing mechanics will stay intact and the contact point relative to the body will stay the same but the legs will be used for more up and out. If you emphasize high contact from the beginning you will lose the forearm to racquet angle and the ability to go through the ball and end up with a slower serve that often goes into the net and or to a righty's forehand.

These are interesting photos and interesting data. What about the contact point inside the baseline?

But I agree with @J011yroger that there are a lot of moving parts that are more important than absolute height of contact.
Flat fast serves are great. However, Sam Stosur and Patrick Rafter did a lot without hitting flat serves. And Thiem uses a very heavy serve to setup his points. The rumor was that Sampras could hit 20 mph faster than he did but opted to hit with much more spin which gave him a big advantage.
Unless, your son can hit over 130 mph with a flat serve consistently, I think variation in spin will get him a lot farther. It will also allow him to use the serve as a setup for what he wants to do.
Even world class servers like Roddick and Sampras, eventually met someone who could neutralize their serves. The question is what to do when the serve is neutralized.
Nadal and Federer are masters at using the serve as a setup.
Because their serve speed is not considered to be elite by pro standards, they may serve as the ultimate tactical guide for rec and junior players.

I'm going to ruffle some feathers and say that contact height is absolutely critical, Its all important but the height of contact rains supreme! Its so important as to take priority over every thing else. However this assumes your son is fundamentally sound to begin with.
After the fundamentals have been learned ( not necessarily mastered yet) contact height becomes crucial because it directly effects net clearance and the amount of energy you can create with your swing. The higher the contact the higher the net clearance, The higher the contact the "longer" you are making your limbs, You can gain a lot of inches by extending at contact more than you think you have to. Jumping to get the extra height at contact doesn't have the same benefits of stretching and extending. I'm not saying don't jump. Jumping is more of byproduct.
Try having your son keep his feet on ground and really extend to increase contact height. I teach a student to imagine reaching to a high shelf to get a book down, Really reach and stretch as far as you can. If you practice it enough the muscles in the Pectoral Region will let you know your doing it correctly.Last edited by Error; 01-05-2020, 08:20 PM.

2 questions.
1) What is the position of the elbow, wrist and racquet head at contact? Are they perfectly straight or a bend? Trying to visualize what ur saying.
2) Does the contact height vary with type of serve? Slice, topspin or flat?
