Frequently Asked Questions
What is a good vertical jump?
For adult males: 16-20 inches is average, 20-24 is above average, 24-28 is good, 28+ is very good, 36+ is elite. For females, subtract about 4-6 inches from each range. NBA players average 28-34 inches.
How is vertical jump measured?
The most common method is the standing reach test: measure your reach while standing flat-footed, then subtract it from your maximum jump reach. Other methods include force plates (flight time) and jump mats.
How can I improve my vertical jump?
Focus on plyometric exercises (box jumps, depth jumps), strength training (squats, deadlifts, lunges), and explosive training. Consistent training can improve vertical jump by 2-6 inches over several months.
