How the calculation works
V16 calculation/specification: return babyHeight,babyWeight,ageMonths as the baby-clothing sizing profile; final labelled size must be selected from the exact clothing brand's current height/weight chart, with ageMonths only as a secondary reference.
Worked example
Example: Baby length/height = 68 cm; Baby weight = 8 kg; Age in months = 6. 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 baby clothes size do i need, the limiting result on this page is baby clothing sizing 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.
