What Is the Dunk Calculator?

The Dunk Calculator is a web-based tool that tells you whether you can dunk a standard 10-foot basketball hoop. It calculates the total height your hands can reach in the air (standing reach + vertical jump) and compares it to the rim height.

If your reach is equal to or greater than 120 inches (10 ft) — congratulations, you can dunk!

📲 How to Use the Dunk Calculator

🪜 Step 1: Measure Your Height

Use a measuring tape or enter your known height in inches. For example:

• 6 feet = 72 inches
• 5’10” = 70 inches

💡 Why height matters: It gives an idea of your potential reach.

✋ Step 2: Measure Your Standing Reach

Stand flat against a wall, raise your arm fully overhead, and mark the highest point you can reach without jumping. Measure the distance from the floor to the mark. This is your standing reach.

📝 Example: A 6’0″ (72″) person usually has a standing reach of around 90 inches.

🦘 Step 3: Measure Your Vertical Jump

You can use a jump test at a gym, or measure it at home:

• Stand next to a wall, reach and mark the spot.
• Jump as high as you can and mark again.
• The difference between the two marks is your vertical jump.

🔢 Example: 30-inch vertical jump

✅ Step 4: Input Your Data

Enter your:

• Height (in inches)
• Standing Reach (in inches)
• Vertical Jump (in inches)

📊 How the Tool Calculates

textCopyEditStanding Reach + Vertical Jump = Dunk Reach
If Dunk Reach ≥ 120 inches (10 feet), you can dunk.

🧠 Example:

• Standing Reach: 90″
• Vertical Jump: 30″
• Total: 120″

Result: You Can Dunk! 🏀

🧠 Why This Tool Matters

• Great for training progress
• Useful for basketball coaches and athletes
• Simple and fast calculation — no signup, no email

❓ FAQs

What is the average vertical jump for dunking?

Typically, a vertical jump of 28 to 34 inches is needed, depending on your standing reach.

What if I’m close but not there yet?

You’re on the edge! Improve with jump training like squats, plyometrics, or resistance bands.

Can shorter players dunk?

A: Yes — it’s rare, but with elite verticals (40+ inches), players under 6 feet have dunked.

Is the rim height always 10 feet?

Yes, standard basketball rims are always set at 120 inches (10 feet).
