How Tall Do You Have To Be To Dunk?

Height To Dunk

To dunk a basketball, you must be tall enough to reach the hoop. The average height of an NBA player is around 6 feet 7 inches, but you do not need to be that tall to dunk. Some players in the NBA are shorter than 6 feet 7 inches and can still dunk the ball. If you are taller than 6 feet 2 inches, you should be able to dunk a basketball.

Requirements To Dunk A Basketball:

Standing Reach

Tall Basketball Player

To dunk, basketball players need a standing reach of at least 28 inches. That means they need to be able to touch the rim of the hoop with their fingertips while standing flat-footed.

Players with a shorter standing reach can still dunk, but they might need a little help. A shorter player can use a mini-trampoline to give them a little boost or ask taller teammates to give them a lift.

Vertical Jump

You must jump high enough to dunk to get the ball over the basket’s rim. The higher you can jump, the easier it is to dunk. The average vertical jump for a person who is 6 feet tall is about 30 inches. That means that you need to be able to jump at least two feet off the ground to dunk. If you’re not quite tall, don’t worry, there are still ways to increase your vertical jump so that you can throw down like a pro.

If you have a short wingspan and are not very tall, it will be more difficult for you to dunk. The average wingspan of an NBA player is about 7 feet. If you are taller than that, then it will be easier for you to dunk. Some players have a shorter wingspan but can still dunk because they have a lot of power and are very athletic.

  1. Challenging: 5 Feet 7 Inches – 5 Feet 9 Inches

You need to be at least 5 feet 7 inches tall to dunk. This is the absolute minimum height requirement. If you are any shorter than this, you will not be able to dunk, no matter how hard you try. If you barely meet this height requirement, you will likely need to put in a lot of effort to succeed.

Those taller than 5 feet 7 inches have a significant advantage in dunking. For example, someone 5 feet 9 inches tall only needs to jump about 6 inches off the ground to reach the basket’s rim. This is much easier than the 12 inches someone only 5 feet 7 inches would need to jump.

It can be quite challenging to dunk if you’re on the shorter side, around 5 feet 10 inches. You’ll need to have a lot of power and perfect your timing to get the ball high enough. Even then, you might only be able to do it if you get a running start.

For those who are taller, around 6 feet or more. You still need power and timing, but you have a bit of an advantage regarding reach. If you can get your hand above the rim, you have a good chance of slam-dunking the ball.

  1. Standard: 6 feet 1inch – 6 feet 3 inches

If you have the standard height or taller, then dunking is not as difficult as it may seem. Many people who are 6 feet 1 inch or 6 feet 3 inches can easily dunk a basketball. The key is to have a strong vertical jump. You can easily slam the ball through the hoop if you can get your body high enough off the ground.

  1. Easy: 6 feet 4 inches and above

For someone 6 feet 4 inches or taller, dunking is relatively easy. All you need is some upper-body strength and some coordination.

How Can I Improve My Vertical Jump To Dunk?


Focus on exercises that target your quads, hamstrings, and glutes. These muscle groups will give you the most power in jumping.

Proper Form:

Make sure you’re using proper form when jumping. You want to explode from the ground, not simply jump straight up.


Be patient and consistent with your training. Vertical jumps take time and practice to improve.
