What is a Dunk Calculator?
The Dunk Calculator helps you discover exactly how high you need to jump to dunk a basketball. It calculates your required vertical jump based on your height, standing reach, and rim height. It also takes into account the extra clearance needed above the rim so you can complete a dunk, not just touch the rim.
The calculator uses this formula:
Required Vertical Jump = (Rim Height + Extra Clearance) minus Standing Reach
If your vertical jump is higher than the required number, you can dunk. It is that simple.

Frequently Asked Questions
Most players need a vertical jump between 28 to 34 inches to dunk on a standard 10-foot rim. The exact number depends on your height, standing reach, and how much clearance you need above the rim to complete the Dunk.
To dunk successfully, you typically need around six inches of clearance above the rim. This extra space allows you to grab and control the ball while completing the dunk motion safely.
Yes, a running jump usually helps you jump higher than a standing jump because it allows you to use forward momentum to generate more power and lift.
If you are 5 feet 8 inches tall and can touch a 10-foot rim, your vertical jump is approximately 32 to 36 inches, depending on your standing reach. Most players of this height have a standing reach of about 7’5″ to 7’7″. Touching the rim would require reaching 10 feet, so the difference between your reach and rim height equals your vertical.
Here is a rough guide to average standing reach by height:
• 5’6 “: around 7’2”
• 5’8″: around 7’4″ to 7’5″
• 6’0″: around 7’8″ to 7’9″
• 6’2″: around 7’10” to 8’0″
• 6’4″: around 8’1″ to 8’2″
Standing reach varies depending on the wingspan and arm length.
If you are 6 feet tall, you typically need a vertical jump of 28 to 32 inches to Dunk. This assumes a standing reach of around 7’9″ and about six inches of extra clearance required for the Dunk.
If you are 6 feet 1 inch tall, your standing reach is usually around 7’10”. You would need a vertical jump of about 27 to 31 inches to dunk on a standard 10-foot rim.
If you are 6 feet 2 inches tall, your standing reach is roughly 7’11” to 8’0″. You would need a vertical jump of about 26 to 30 inches to dunk comfortably.
The term dunk calculator squat is often searched because athletes want to know how squats can improve their vertical jump. While there is no direct calculator for squats alone, increasing your squat strength (both in absolute terms and relative to your body weight) can directly improve your vertical jump, which you can track using this Dunk Calculator.
A standing reach calculator estimates how high you can reach while standing flat-footed with one arm fully extended. You can measure this by standing against a wall or using estimated values based on your height and wingspan. Our Dunk Calculator lets you enter this number to personalize your result.
A vertical jump calculator estimates how high you can jump from a standing or running start. You can input your jump height into our Dunk Calculator to see if it is high enough to dunk.
