How to Use 6-Minute Walk Test Calculator
Use 6-Minute Walk Test Calculator after a completed six-minute walk test. Enter the actual walking distance in meters, then enter age, sex, and height so the calculator can estimate a predicted reference distance.
The main result is percent predicted. A person walking 520 m with a predicted value of 600 m would score about 86.7%, which is easier to interpret than distance alone.
Formula & Theory - 6-Minute Walk Test Calculator
The core calculation is:
Male predicted distance = 867 - 5.71 × age + 1.03 × height(cm)
Female predicted distance = 525 - 2.86 × age + 2.71 × height(cm)
Percent predicted = actual distance / predicted distance × 100The calculator uses simplified sex-specific prediction equations based on age and height. Older age lowers predicted distance, while greater height generally raises it because stride length and body size affect walking capacity.
Percent predicted is not the same as a diagnosis. Testing corridor length, encouragement, oxygen use, assistive devices, musculoskeletal limitations, and cardiopulmonary disease can all influence the measured distance.
Use Cases for 6-Minute Walk Test Calculator
Use it in pulmonary rehabilitation, cardiology follow-up, preoperative assessment, or exercise-capacity education to place a walking distance in context.
It is especially useful for tracking change over time: the same patient can compare percent predicted before and after rehabilitation rather than relying only on raw meters.
