How the calculation works
V16 calculation/specification: return playerAge,competitionRuleSize as the football sizing profile; final ball size is competitionRuleSize when supplied from the current league or governing-body rule for playerAge.
Worked example
Example: Player age = 12; Competition mandated size = 2. Result: Use this measurement profile with the exact current manufacturer, brand or governing-body chart; no universal labelled size is assumed.
Before you decide
The result is only as accurate as the measurements entered. 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 football size do i need, the limiting result on this page is football size requirement.
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.
