How the calculation works
V16 calculation/specification: return chest,waist,shoulderWidth,sleeveLength as the shirt sizing profile; final labelled size must be selected from the exact shirt brand's current chart using the limiting measurement.
Worked example
Example: Chest circumference = 100 cm; Waist circumference = 86 cm; Shoulder width = 46 cm; Sleeve length = 64 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
Use measured dimensions rather than nominal labels. 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 shirt size do i need, the limiting result on this page is shirt 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.
