The Math Behind Dunking
A basketball rim is 10 feet (305 cm) high. To dunk, you need to get your hand approximately 6 inches (15 cm) above the rim to control the ball. That means reaching about 10 feet 6 inches (320 cm).
Required Vertical = 320 cm - Your Standing Reach
Requirements by Height
Here are approximate vertical jump requirements (assuming average arm length):
| Height | Standing Reach | Vertical Needed |
|--------|---------------|-----------------|
| 5'6" (168 cm) | ~7'2" (218 cm) | ~40" (102 cm) |
| 5'9" (175 cm) | ~7'5" (226 cm) | ~37" (94 cm) |
| 6'0" (183 cm) | ~7'9" (236 cm) | ~33" (84 cm) |
| 6'3" (191 cm) | ~8'1" (246 cm) | ~29" (74 cm) |
| 6'6" (198 cm) | ~8'5" (257 cm) | ~25" (64 cm) |
Factors That Affect Your Requirements
Wingspan: Longer arms mean higher standing reach and lower vertical requirements.
Hand size: Larger hands make it easier to control the ball, potentially reducing the height needed.
Approach: A running approach adds 4-8 inches to your jump compared to standing.
Is Dunking Realistic?
For most people under 6 feet tall, dunking requires an elite-level vertical jump (35+ inches). It's achievable but requires dedicated training over months or years.
For those 6'2" and above with average proportions, dunking is more accessible with a good training program.
Start With Your Numbers
Measure your standing reach accurately. This tells you exactly how high you need to jump. Then create a training plan targeting that specific goal.
