Visual Analysis of Vertical Jump:
With this tool you can easily analyze vertical jumps of all heights! Check the height of the jumper at any point during the jump in the graph below and find out how much hang time you have at different jump heights.
You can also see how fast the takeoff velocity is , how quickly a jumper is high enough to dunk (speed of dunk) and how long he is high enough in the air to still dunk (effective hang time).

Interesting facts when analyzing Vertical Jumps :
- When you are asking yourself: "How tall do I have to be to dunk?" - you are asking the wrong question! Wingspan is also very important as it is a big part of the standing reach.
- If you have a vertical jump of 100cm you will be spending more than 50% of the hang time above 72cm. This explains why it oftens seams as if a jumper is "stopping" mid air.
- If you can jump just high enough to squeeze in dunks right now, then an improvement of only a few inches can have a huge impact. For example if you need a jump height of 30 inches to dunk and you can jump exactly 30 inches you have an effective hang time of 0.39 seconds. This will be the fastest time in which you can complete a dunk. If you improve your vertical jump by only 2 inches your effective hangtime increases by 30% to 0.51 seconds giving you much more time in the air for stuff like windmills. The speed of the dunk becomes much faster as you can complete a dunk within 0.31 seconds making you much harder to block!
- While small dunkers have to train a lot more to make a dunk they also have the advantage of great hang time.
