Enter the measurements above to calculate suit sizing measurements.
How the calculation works
V16 calculation/specification: drop=chest-waist; return chest,waist,sleeveLength,inseam,drop as the suit sizing profile; final jacket and trouser labels must be selected from the exact tailoring or brand chart.
Worked example
Example: Chest circumference = 100 cm; Waist circumference = 86 cm; Sleeve length = 64 cm; Trouser inseam = 80 cm. Result: Drop = 14 cm. Final labelled size/compatibility must be checked against the exact current manufacturer, brand or governing-body chart.
Before you decide
Use the finished, usable dimensions after trim, handles, skirting, packaging or other projections where relevant. 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 suit size do i need, the limiting result on this page is suit 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.
