What Percent of People Can Dunk?
Dunking a basketball is one of the most electrifying moves in sports. But how many people can actually do it? The answer might surprise you.
The Short Answer
Only about 1% of the general population can dunk a basketball. This elite group primarily consists of individuals who are either naturally tall, exceptionally athletic, or both. While dunking seems commonplace when watching professional basketball, it’s actually an incredibly rare skill in the real world.

Why Is Dunking So Rare?
Several factors make dunking challenging for most people:
Height Requirements
A standard basketball rim sits at 10 feet (120 inches) high. For most people to dunk, they need to get their wrist above the rim, which typically requires a standing reach of at least 8 feet combined with a vertical jump of 24-30 inches. The average male standing reach is around 7'7" to 8'0", meaning most men would need a vertical jump of 28-35 inches to dunk.
Vertical Jump Statistics
The average vertical jump varies significantly by demographics. Adult males typically jump between 16-20 inches, while adult females average 12-16 inches. This falls well short of what's needed to dunk. Elite athletes and professional basketball players often have verticals exceeding 35-40 inches, placing them in the top 0.1% of the population.
Physical Requirements
Dunking requires a combination of height, explosive leg power, hand size to palm the ball, and overall athleticism. Most people lack one or more of these critical factors. Even individuals with good vertical jumps may struggle if they can't securely grip the basketball.
Breaking Down the Numbers by Group
General Adult Male Population
Approximately 1-2% of adult males can dunk, and most of these individuals are over 6 feet tall. For men under 6 feet, the percentage drops to well below 0.5%.
General Adult Female Population
Less than 0.01% of adult females can dunk. Only a handful of women have ever dunked in a WNBA game, highlighting how rare this ability is even among elite female athletes.
College Basketball Players
Among male college basketball players, roughly 35-45% can dunk. This percentage varies significantly by division, with Division I players being much more likely to dunk than Division III players.
High School Basketball Players
Only about 10-15% of high school male basketball players can dunk consistently. This increases dramatically for players over 6'2" or those with exceptional athleticism.
Professional Basketball Players
Nearly 100% of NBA players can dunk, though this represents only about 450 people worldwide at any given time.
Can You Learn to Dunk?
The good news is that with proper training, many people can significantly improve their vertical jump. Plyometric exercises, strength training, and technique work can add 8-12 inches to your vertical over 6-12 months of dedicated training.
However, biological factors like height and limb length create hard limits for some individuals. A person who is 5'6" with average genetics would need an extraordinary vertical jump (40+ inches) to dunk, which is beyond what most can achieve even with excellent training.
Use Our Dunk Calculator
Want to know exactly how high you need to jump to dunk? Our dunk calculator above takes your height and standing reach to calculate your personalized vertical jump goal. Simply enter your measurements and discover whether dunking is within your reach with training, or if you're already close to achieving this impressive feat.
What Vertical Jump Do You Need?
The vertical jump needed to dunk depends entirely on your standing reach:
- If your standing reach is 7'6": You need a 36-inch vertical
- If your standing reach is 8'0": You need a 30-inch vertical
- If your standing reach is 8'6": You need a 24-inch vertical
- If your standing reach is 9'0": You need an 18-inch vertical
Use the calculator above to find your exact number based on your personal measurements.
The Bottom Line
While dunking is extremely rare in the general population, it's not impossible for dedicated athletes who meet certain physical requirements. If you're under 6 feet tall, you'll need exceptional vertical jumping ability. If you're over 6'4", you may need only moderate jumping ability combined with proper technique.
The 1% figure represents the current reality, but with the right training program, genetics, and dedication, some individuals can join this elite group. The key is understanding your starting point and setting realistic goals based on your unique physical attributes.
