How to measure

Reach up flat-footed against a wall and mark it — that is your standing reach. Then jump and touch as high as you can. The gap is your vertical.

Flat-footed reach, in inches.

Highest point you can touch on a jump, in inches. (10-ft rim = 120 in.)

Your vertical
22 inches

A 22-inch vertical rates as "above average". Better than most rec players. You are getting good hip and ankle drive.

How do you calculate vertical jump?

Vertical jump equals your maximum one-hand jump-touch height minus your standing reach. Reach up flat-footed and mark it, then jump and touch as high as you can — the difference is your vertical.

What is a good vertical jump?

For a recreational adult, 16–20 inches is average and 24+ inches is good. Competitive high-school players often reach the low-to-mid 20s, and college athletes 26–30 inches.

What vertical do you need to dunk?

It depends on your standing reach. To dunk on a 10-foot rim you need your jump-touch to clear roughly 126 inches (the rim plus room for the ball). If your standing reach is 7'6" (90"), that means about a 36-inch vertical.

How can I increase my vertical jump?

Combine lower-body strength (squats, deadlifts) with plyometrics (box jumps, depth jumps, jump rope) two to three times a week, and give yourself recovery days. Most players add several inches over a few months of consistent training.
