How the calculation works
V16 calculation/specification: return chest,waist,bodyLength,fitPreference as the T-shirt sizing profile; final labelled size must be read from the exact garment brand's current chart.
Worked example
Example: Chest circumference = 100 cm; Waist circumference = 86 cm; Shoulder-to-hem length = 70 cm; Fit preference = regular. Result: Use this measurement profile with the exact current manufacturer, brand or governing-body chart; no universal labelled size is assumed.
Before you decide
Measure the actual item, opening or body dimension involved. 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 t-shirt size do i need, the limiting result on this page is t-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.
