FAQ
How does this dunk calculator work?⌄
Enter your height, standing reach, and current vertical jump. The calculator compares your max reach to the 10-foot rim plus 6 inches of clearance and tells you exactly how many more inches of vert you need.
How tall do you have to be to dunk a basketball?⌄
There is no minimum height. A 5'9" player with a 40-inch vertical can dunk, while a 6'3" player with a 20-inch vert cannot. Standing reach + vertical jump is what matters.
What vertical do I need to dunk?⌄
Take 126 inches (10-foot rim + 6 inches clearance) and subtract your standing reach. That number is your required vertical. The calculator above does it instantly.
How do I measure my standing reach?⌄
Stand flat-footed against a wall, reach straight up with one hand, and mark the highest point your fingertips touch. Measure from the floor to the mark.
Can I add inches to my vertical to dunk?⌄
Yes. Most athletes add 2–6 inches in 8–12 weeks with structured strength and plyometric training.
Is the dunk calculator free?⌄
Yes — the Hooper Lab dunk calculator is 100% free, no signup required.
