Dunk Calculator
Purpose of building this dunking calculator is to find out if a player can successfully dunk a basketball.
The Dunk Calculator considers several key factors:
- Hoop Type: The type of basketball hoop being used (standard, adjustable, etc.)
- Hoop Height: The height of the rim from the ground
- Body Weight: The player’s weight
- Playing Height: The player’s height while wearing basketball shoes
- Standing Reach: The highest point a player can reach while standing flat-footed
- Minimum Vertical Leap: The player’s vertical jumping ability
- Hang Time: The amount of time a player can stay airborne during a jump
- Jumping Energy: The power generated during the jump
- Initial Jumping Speed: The speed at which the player leaves the ground
By analyzing these factors, the NBA sports calculator provides insights into a player’s dunking potential and can help athletes set realistic goals for improving their vertical leap and overall jumping ability.
Dunking Calculation Formula
Dunking Potential = (Playing Height + Standing Reach + Vertical Leap) - Hoop Height
If the Dunking Potential is greater than zero, it suggests that the player has the physical capability to dunk.
Dunking Potential = ((Playing Height + Standing Reach + (Vertical Leap * Hang Time Factor)) * Jumping Energy Factor) - Hoop Height
Where:
- Hang Time Factor is a multiplier based on the player’s ability to stay airborne
- Jumping Energy Factor is a multiplier representing the player’s explosive power
These factors would need to be calibrated based on empirical data and biomechanical analysis to provide accurate results.

Is it possible for a 5’7″ player to dunk?
While challenging, it is possible for a 5’7″ (170 cm) player to dunk, although it requires exceptional athleticism and vertical leaping ability.
To dunk on a standard 10-foot (305 cm) hoop, a 5’7″ player would need to make up about 35 inches (89 cm) in vertical leap and reach.
Assuming an average standing reach for someone of this height (around 7’2″ or 218 cm), they would need a vertical leap of about 34 inches (86 cm) to touch the rim.
To successfully dunk, they’d likely need a vertical of 40+ inches (102+ cm), which is in the realm of elite NBA-level athleticism.
Is it harder to dunk off 1 or 2 feet?
Dunking off one foot:
- Allows for a faster approach and more momentum
- Often preferred by players with exceptional speed and leaping ability
- Can provide better body control and maneuverability in the air
- Typically allows for a higher vertical reach
Dunking off two feet:
- Provides more stability and power
- Often preferred by stronger, more physical players
- Can be easier for maintaining balance upon landing
- May be more suitable for players who aren’t as fast but have good lower body strength
Many players find it easier to dunk off one foot when approaching from an angle or after a run-up, while two-foot jumps are often preferred when jumping straight up from a stationary position under the basket.
The easier method varies from player to player, and many skilled dunkers practice both techniques to be versatile in different game situations.
How many inches vertical to dunk?
Here’s a general guideline:
- For a 6’0″ (183 cm) player with average proportions:
- Standing reach: ~8’0″ (244 cm)
- Vertical needed to touch rim: ~24 inches (61 cm)
- Vertical needed to dunk: ~32 inches (81 cm)
- For a 6’6″ (198 cm) player:
- Standing reach: ~8’6″ (259 cm)
- Vertical needed to touch rim: ~18 inches (46 cm)
- Vertical needed to dunk: ~24 inches (61 cm)
- For a 5’10” (178 cm) player:
- Standing reach: ~7’8″ (234 cm)
- Vertical needed to touch rim: ~28 inches (71 cm)
- Vertical needed to dunk: ~36 inches (91 cm)
These estimates assume a standard 10-foot (305 cm) hoop and that the player needs to get the ball about 6 inches above the rim to dunk successfully.
The actual vertical needed may vary based on individual arm length, hand size, and jumping technique.
Is it possible to dunk 12 feet?
Dunking on a 12-foot (366 cm) hoop is extremely challenging and beyond the capabilities of most basketball players, including many professionals.
To put this in perspective:
- A standard basketball hoop is 10 feet (305 cm) high
- The world record for highest dunk is 12 feet 2.5 inches (372 cm), set by Jordan Kilganon in 2016
To dunk on a 12-foot hoop, a player would need:
- Exceptional height (likely 6’6″ or taller)
- An extraordinary vertical leap (50+ inches or 127+ cm)
- Excellent timing and hand-eye coordination
While not impossible, dunking at 12 feet is a feat achieved by only a handful of individuals with elite athleticism and is not a realistic goal for the vast majority of basketball players.
What is your vertical if you can touch rim at 5’8″?
For a player who is 5’8″ (173 cm) tall and can touch the rim of a standard 10-foot (305 cm) hoop, we can estimate their vertical leap as follows:
- Estimate standing reach:
- Average standing reach for 5’8″ person: ~7’4″ (224 cm)
- Calculate vertical leap:
- Rim height: 10’0″ (305 cm)
- Standing reach: 7’4″ (224 cm)
- Difference: 2’8″ (81 cm)
A 5’8″ player touching the rim likely has a vertical leap of about 32 inches (81 cm), which is an impressive vertical for someone of this height.
How high do you have to jump to dunk at 6’2″?
For a 6’2″ (188 cm) player to dunk on a standard 10-foot (305 cm) hoop:
- Estimate standing reach:
- Average standing reach for 6’2″ person: ~8’2″ (249 cm)
- Calculate required vertical:
- Rim height: 10’0″ (305 cm)
- Standing reach: 8’2″ (249 cm)
- Difference to touch rim: 1’10” (56 cm)
- Add ~6 inches to get the ball over the rim
A 6’2″ player would need approximately a 28-inch (71 cm) vertical leap to dunk comfortably. This is within reach for many athletic basketball players of this height with proper training.
How high do you have to jump to dunk at 5’10”?
For a 5’10” (178 cm) player to dunk on a standard 10-foot (305 cm) hoop:

- Calculate required vertical:
- Rim height: 10’0″ (305 cm)
- Standing reach: 7’8″ (234 cm)
- Difference to touch rim: 2’4″ (71 cm)
- Add ~6 inches to get the ball over the rim
A 5’10” player would need approximately a 34-inch (86 cm) vertical leap to dunk comfortably. This is a challenging but achievable goal for dedicated athletes at this height.
How high do you have to jump to dunk at 6’1″?
For a 6’1″ (185 cm) player to dunk on a standard 10-foot (305 cm) hoop:
- Estimate standing reach:
