How the Dunk Calculator works

Step 1: Enter Your Measurements

Enter your height and standing reach, or let the Dunk Calculator estimate your standing reach based on your height. You can also set your desired rim height for your dunk.

Step 2: Define Your Dunk Goal

Choose how many inches above the rim you want to reach for your dunk. The Dunk Calculator helps calculate whether you can touch the rim, dunk normally, or attempt a high-flying Vince Carter-style 360° windmill dunk.

Step 3: Calculate Your Vertical Jump

Click the calculate button, and the Dunk Calculator will instantly compute your required vertical jump height, hang time, take-off velocity, and other key dunk metrics.

Step 4: Review Your Dunk Metrics

See detailed results showing exactly how high you need to jump to dunk a basketball, along with insights on hang time, dunk speed, and whether your current jump is enough for different dunk styles.

Dunk Calculator: Frequently Asked Questions

1. How high do I need to jump to dunk?

The height you need to jump to dunk depends on your standing reach and the rim height. For a standard 10-foot rim, most players need a vertical jump of at least 28 to 34 inches. Use the Dunk Calculator to enter your height, standing reach, and rim height to find your exact jump requirements.

2. What vertical do I need to dunk?

Most people need a vertical jump between 28 and 34 inches to dunk on a standard 10-foot rim. The exact vertical depends on your height and standing reach. The Dunk Calculator helps you calculate the precise vertical jump needed to dunk a basketball.

3. Can a 6-foot guy dunk?

Yes! Many 6-foot players can dunk, especially if they have decent athleticism. A vertical of around 30 inches is typically enough for a 6-foot player to dunk. You can check your exact numbers using the Dunk Calculator to see how high you'd need to jump.

4. How tall do you have to be to dunk?

There's no minimum height to dunk—a shorter player just needs a higher vertical jump. Players around 5'7" to 5'9" often need 35 inches or more of vertical leap. The Dunk Calculator can help you determine if your height and jump are enough to dunk.

5. Can I dunk if I'm 5'7"?

It's possible! A 5'7" player generally needs a vertical jump of around 35-40 inches to dunk on a 10-foot rim. Enter your data into the Dunk Calculator to see the exact vertical jump you'd need.

6. What is my standing reach if I'm 5'9"?

For someone 5'9", the average standing reach is around 7'5" to 7'7". However, arm length varies by individual. The Dunk Calculator can estimate your standing reach if you only know your height, helping you determine your dunk potential.

7. Is dunking a skill or just about jumping high?

Dunking definitely requires skill—timing, ball control, and technique matter as much as vertical jump. Even with enough height, poor technique can prevent a dunk. The Dunk Calculator shows how high you need to jump, but practicing technique is key.

8. How to jump higher to dunk?

Improving your vertical involves strength training, plyometrics, and proper jumping technique. Exercises like squats, calf raises, and box jumps help. Use the Dunk Calculator to set a vertical jump goal, then train to reach it.
