Standing Broad Jump Percentile Calculator
See where your standing broad (long) jump ranks against adult norms as a percentile, using sex-specific averages.
How it works
z = (jump − mean) ÷ SD · percentile = Φ(z) × 100 (mean 80 in / SD 12 male, 64 in / SD 10 female)
The standing broad jump measures explosive horizontal power off two feet. Ranking it as a percentile assumes distances are roughly normally distributed around a sex-specific average, so a z-score of 0 sits at the 50th percentile and every standard deviation moves you about 34 percentile points. The averages here reflect general active adults, not trained athletes — competitive jumpers routinely exceed the 99th percentile of this reference.
Worked example
A man jumping 100 in is (100 − 80) ÷ 12 = 1.67 standard deviations above the mean. The normal CDF of 1.67 is about 0.952, so that is roughly the 95th percentile.
Frequently asked questions
Broad jump versus long jump — same thing?
The standing broad jump is a no-run, two-foot takeoff and is what combines test. The track long jump uses a full approach run and produces far greater distances, so the two are not comparable.
What is a good standing broad jump?
For adult men, roughly 8 feet (96 in) is strong and 10 feet (120 in) is elite; for women about 6.5–7 feet is strong. NFL combine standouts clear 10–11 feet.
How is the percentile calculated?
Your distance is turned into a z-score against sex-specific population averages, then converted to a percentile with the normal distribution. It is an estimate, not a validated test battery.
