Frequently asked questions

Which chart should I use?

WHO charts for 0-2 years, CDC charts for 2-20 years. Both are valid.

Any percentile can be healthy. Consistent growth along their curve matters most.

Health metrics give you a snapshot of where you stand, but they are not a diagnosis. WHO charts for 0-2 years, CDC charts for 2-20 years. Both are valid. Basal metabolic rate estimates use equations like Harris-Benedict or Mifflin-St Jeor, which factor in age, sex, height, and weight. Reference ranges published by organizations like WHO and NIH apply to general adult populations and may not suit everyone. Try adjusting one input at a time to see how it affects the outcome — this is the fastest way to build intuition about the relationship between the variables.
