- Approach at 45° angle for one-hand dunks
- Two-hand dunks require more height
- Practice with smaller ball first
- Lower rim to build confidence
- Jump off two feet for power
Progress Tracking

Frequently Asked Questions
How high do I need to jump to dunk?
You need your touch height (standing reach + vertical jump) to be at least 10-12 inches above the rim for a comfortable two-handed dunk. For one-handed dunks, 6-8 inches above rim is usually enough. The rim is 10 feet (120 inches) high.
What's the average vertical jump for someone who can dunk?
For a 6'0" person (approx 7'8" standing reach), you'd need about 28-30 inch vertical to dunk. Most recreational dunkers have 25-30 inch vert. NBA players average 28 inches but are taller.
Can short people dunk?
Yes! Spud Webb (5'7") won the dunk contest. Muggsy Bogues (5'3") could dunk in practice. It requires exceptional vertical (40+ inches) and technique. Height is not a limit, just makes it harder.
How accurate is this calculator?
Our calculator uses the standard formula: Touch Height = Standing Reach + Vertical Jump. For clean dunks, you need 6-12 inches above rim depending on hand size and dunk style. Accuracy depends on your measurements - we recommend measuring standing reach against a wall.
What's the difference between one-hand and two-hand dunks?
One-hand dunks require less height because you can palm the ball and reach higher. Two-hand dunks need more clearance (8-12 inches above rim) since both hands are on the ball. Most beginners should aim for one-hand first.
Basketball Dunk Calculator: Find Your Vertical Jump Requirements & Training Plan
Welcome to the most accurate basketball dunk calculator on the web, used by over 50,000 athletes at tools.tecdud.com. Whether you're a beginner dreaming of your first dunk or an experienced player tracking progress, our tool provides precise calculations based on your height, standing reach, and vertical jump.
The science of dunking: A standard basketball rim is 10 feet (120 inches) high. To dunk, your touch height (standing reach + vertical jump) must exceed the rim by at least 6 inches for a one-handed dunk, and 10-12 inches for a powerful two-handed dunk. Factors like hand size, arm length, and jumping technique also play crucial roles.
How to use this calculator: Enter your height and vertical jump. If you know your standing reach, enter it for maximum accuracy. If not, we'll estimate based on average proportions (standing reach is typically 1.3x your height). Select your preferred dunk style - one-handed is easier for beginners.
Training to dunk: Most athletes can increase their vertical by 4-8 inches in 3-6 months with proper training. Focus on strength training (squats, deadlifts), plyometrics (box jumps), and technique work. Our calculator shows exactly how much more vertical you need to achieve your dunking goal.
