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.

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.

You are about 14 inches of touch short of a two-hand-clear dunk on a 10-foot rim.
Standing reach by height — and your vertical if you can touch the rim
Standing reach is the number the whole calculation hangs on: your vertical is jump-touch minus
reach, so a wrong reach makes every other figure wrong. Measure it flat-footed against a wall with
one arm fully extended and mark the highest point your fingertips touch — shoes on, heels down.
If you cannot measure it right now, reach is roughly height × 1.33.
Touching a 10-foot rim means your jump-touch reached 120 inches, so your vertical is 120 minus your
reach; a one-hand dunk needs about 6 inches more:

Treat these as a starting point, not a measurement. Arm length varies by several inches between
players of the same height, which is exactly why the estimate is the weakest link in any vertical
you calculate from it.
How to measure your vertical jump
The formula is one subtraction: vertical = maximum jump-touch − standing reach.
Both numbers have to be measured the same way, on the same surface, in the same shoes.
Mark your standing reach. Stand flat against a wall, heels down, reach up with
your dominant arm and mark the highest point your fingertips reach.
Chalk your fingertips. Chalk, tape or a wet fingertip leaves a mark you can
actually measure rather than one you have to guess at.
Jump and touch. Take your normal approach — two-foot or one-foot, whichever you
would use in a game — and touch as high as you can. Do three attempts and keep the best.
Subtract. Highest touch minus standing reach. That difference is your vertical,
and it is what the calculator above wants.
A running vertical usually measures two to four inches higher than a standing one, so record which
you used. Comparing a running touch against a standing benchmark flatters the number.
Already know you can touch the rim? A 10-foot rim is 120 inches, so your vertical is 120 minus your
standing reach — the rim-touch table on the dunk
calculator works that out by height.
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.
