 Weight for Height Percentile Interpretation

 
Percentile < 5: Underweight
Percentile >= 5 and < 85: Healthy weight
Percentile >= 85 and < 95: At risk of overweight
Percentile >= 95: Overweight

 
 

 
Notes
  • These weight-for-stature standards are available as an alternative to BMI for assessment of over or undernutrition in children ages 2-5 years. However, health care providers should consider using the BMI-for-age charts to be consistent with current recommendations.
  • This calculator uses measured standing height for children ages 2 to 5 years, and is not valid for recumbent length.
  • At the extremes (>97th percentile or <3rd percentile), small differences in percentiles represent clinically important differences. At these extremes, the Z-score is a more precise reflection of how far the measurement deviates from the mean and is a useful tool for tracking changes.
  • LMS data used in this calculator are shown in the data table below.
  • For all LMS tables, the row in the table corresponding to the patient-specific value is found in the first column of the table; values to be used for L (the Box-Cox power), M (the median), and S (the generalized coefficient of variation) in the equation for Z-score are retrieved.
  • Z-scores may be used to do a table lookup for the corresponding percentile in the Normal table percentiles for Z-score table (below). Numbers along the left side (Y-axis) of the table represent the first number and first decimal place of the Z-score, while the numbers along the top (X-axis) of the table represent the second decimal position of the Z-score.

 
Equations used
 
ZScore = ((Weight/M)L - 1) / (L * S)
Percentile = ZtoPercentile(ZScore)
