RESULT GUIDE
How to use child growth percentiles 0–5
Place a child’s weight and length or height on the WHO growth standards from birth to 60 months. The estimate uses age- and sex-specific LMS parameters and is intended to show a statistical position, not a diagnosis.
Practical example
- Enter sex, completed age in months, weight and recumbent length or standing height measured with an appropriate technique.
Home measurements and rounding can shift the result. Growth concerns, rapid changes or extreme values should be discussed with a paediatric professional.
How to interpret the result
- The trend across repeated standardised measurements is more informative than a single percentile.
- Change one input at a time to understand which assumption has the greatest effect on the result.
What the estimate does not include
- Home measurements and rounding can shift the result. Growth concerns, rapid changes or extreme values should be discussed with a paediatric professional.
- Use the result as a planning aid and confirm sensitive financial, health or animal-care decisions with the relevant document or qualified professional.
