Vertical Jump Calculator
Calculate measured jump height from standing reach and three jump-reach trials.
Inputs and method
Each trial height = jump reach − standing reach. The highest trial is displayed with the observed range.
All empirical factors, rates, percentages, clearances, product yields, and model values shown as inputs are scenario values supplied by you. Their source or measurement basis appears beside the inputs and result. Units remain visible, calculations use unrounded values, and rounding occurs only for display or a whole-package ceiling.
Interpreting the result
This reach subtraction provides no power, performance-level, readiness, training, safety, or injury conclusion.
Treat scenario ranges as sensitivity ranges, not confidence intervals. Check the factor’s version, geography, population or product, system boundary, and date before using the result. A numerical result does not establish code compliance, certification, safety, forecast accuracy, or model validity.
Validation and rounding
Blank required factors, invalid numbers, prohibited negatives, impossible relationships, and unsupported modes trigger a validation message. Results are rounded as stated; package quantities round up only after waste is applied.
Worked example
A 220 cm standing reach and jump reaches of 273, 275, and 274 cm produce 53, 55, and 54 cm. Best is 55.0 cm and the observed range is 53.0–55.0 cm.
Frequently asked question
Does this assess readiness or injury risk? No. It only subtracts standing reach from three measured jump reaches.
