PowerJumping and straight-line acceleration
Standing countermovement jump with arm swing, no step. Jump-and-reach: highest touch minus standing reach, best of three.

Those two numbers are the whole point. Against everybody — including the majority of adults who never train — a 30-inch vertical jump is genuinely rare. Against people whose job is to be athletic, it is ordinary. A percentile means nothing until you name the population.
Where a 30-inch vertical jump lands
Percentile of an average-size adult at each age, computed with the same code the calculator runs. "General" is all adults of that sex and age; "D1" is NCAA Division I athletes of that sex, pooled across sports by head-count, with no age or size adjustment.
| Who | vs. general population | vs. D1 athletes |
|---|---|---|
| Man, age 25 | 99+ | 77th |
| Man, age 40 | 99+ | 77th |
| Woman, age 25 | 99+ | 99+ |
| Woman, age 40 | 99+ | 99+ |

Questions
Is a 30-inch vertical jump good for a man?
For a 25-year-old man of median US size (179 lb), a 30-inch vertical jump is above the 99th percentile of the general population — and the 77th percentile against pooled NCAA Division I athletes. By 40 the same result is above the 99th percentile of the general population, because the norms fall with age.
Is a 30-inch vertical jump good for a woman?
For a 25-year-old woman of median US size (153 lb), a 30-inch vertical jump is above the 99th percentile of the general population and above the 99th percentile against D1 athletes.
Does bodyweight change the answer?
No. 30-inch vertical jump results are not size-adjusted on this site — the evidence shows this test is essentially independent of how big you are, so the percentile depends only on your age and sex.
How much would I need for the 90th percentile?
A 25-year-old man of median size reaches the 90th percentile of the general population at 24.6 in, and a 25-year-old woman at 16.2 in.
How reliable is this number?
Derived — converted from real data on a closely related measure. Nationally representative Canadian force-plate jump data (CHMS, n=5,188), shifted a few centimetres to match the jump-and-reach method.
