You’ll need to jump roughly 24 inches to touch the rim and 30 inches to dunk a full sized basketball (assuming average arm length). While the height difference between a 5 foot 9 person and a 6 foot person is only 3 inches, it’s actually a lot easier around this height for two reasons.
Easy 6’5 and above. At this height, you will still need to be physically fit to dunk a basketball unless a person is closer to the 7-foot mark…. With barely any vertical training, a person who is 6’5 or taller should be dunking fairly easily. Being this tall lets a person have a huge advantage or an average person.
How tall do you have to be to dunk? The truth is, there is no one required height. While having some extra length helps, as we’ll get into below, you don’t need to be seven feet to get to the rim. There are many people out there who are less than six feet tall who can dunk with relative ease.
Now, the minimum height to dunk depends upon how good your standing reach and vertical jump get. A rough idea, however, of how much height benefits in dunking is as follows: 5’7” – 5’9”: Difficult Enough; Well, it’s not impossible with this height. But you have to improve your vertical jump a lot.
Anyway, considering that basketball hoops are generally mounted 10 feet high from the ground, your vertical jump needs to cover the difference between your standing reach and 10 feet, plus around 6 inches to comfortably reach over the hoop to dunk. So the taller you are, the less you will have to jump.
Professional basketball requirements provide a general view that guides us in deducing the minimum height for dunking in non-competitive scenarios. We know that the standard basketball rim sits at 10 feet above the ground. You don’t need to be 6′ tall to dunk as the shortest professional male dunker Spud Webb is only 5 feet and 7 inches tall.
