Enter the measurements above to calculate climbing harness sizing measurements.
How the calculation works
V16 calculation/specification: return waist,thigh,rise as the climbing-harness sizing profile; choose only a harness whose published waist and thigh ranges contain the required circumferences and whose rise or leg-loop geometry is suitable when rise is supplied.
Worked example
Example: Waist circumference = 86 cm; Upper-thigh circumference = 50 cm; Waist-to-leg-loop rise = 50 cm. Result: Use this measurement profile with the exact current manufacturer, brand or governing-body chart; no universal labelled size is assumed.
Before you decide
Recheck the limiting measurement before purchase or installation. Use the current manufacturer, brand, league or governing-body specification for the final labelled size or rule; those external charts can change and are not treated as universal constants. For what climbing harness size do i need, the limiting result on this page is climbing harness sizing measurements.
Runtime-specific source required. Use the exact current manufacturer, brand, model, regional conversion, league or governing-body chart/rule that applies to the user's actual product or competition; a single static URL would be misleading.
