How to Use the Standing Long Jump Grade Calculator
The standing long jump is a classic fitness test where you jump forward as far as possible from a stationary start, using an arm swing for momentum. It's widely used to assess lower-body explosive power, which is closely tied to sprint speed and vertical jump ability. Enter your gender and jump distance in inches to see your power grade compared to general adult norms.
To measure correctly, stand with feet together behind the takeoff line, swing your arms to build momentum, and jump forward as far as you can. Measure from the takeoff line to the nearest point of contact on landing. The grading bands here (Excellent through Needs Improvement) reflect a general approximation of typical adult distributions, so treat your result as a helpful reference rather than an exact ranking.
If your score landed lower than you'd like, don't worry — explosive power responds well to training. Plyometric drills like squat jumps and box jumps, paired with lower-body strength work such as squats and deadlifts, tend to produce a noticeable improvement within a few weeks of consistent practice two to three times per week.
