Coat size profile
Enter the measurements above to calculate coat size profile.
How the calculation works
V12 calculation: targetCoatChest=chest+layerAllowance; return targetCoatChest,hip,sleeveLength as the coat sizing profile; final labelled size must come from the exact coat brand chart. This is the implementation rule for this calculator.
Worked example
Example: Chest circumference = 100 cm; Hip circumference = 98 cm; Sleeve length = 64 cm; Layering ease allowance = 5 cm. Result: Target Coat Chest = 105 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. This page calculates the stated geometry or quantity only; product-specific construction or installation details can still affect the final choice. For what coat size do i need, the limiting result on this page is coat size profile.
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.
