About Babypercentiles
Babypercentiles draws the official WHO (birth to 24 months) and CDC (2 to 5 years) growth reference curves, weight, length or stature, and head circumference, and plots a child's measurement on them. It is a project of Urban Algorithm LLC.
Quick answer
Is Babypercentiles medical advice?
No. Babypercentiles draws published reference curves and plots the numbers you enter on them. It does not assess, diagnose, or screen anything, and it gives no feeding or growth guidance. A percentile describes position in a reference population, not health; talk to your pediatrician about what any single measurement means for your child.
Where the curves come from
Every curve on this site is drawn directly from the published WHO Child Growth Standards and CDC 2000 Growth Charts parameter tables, not redrawn by eye or estimated. Full detail, including the exact age ranges each dataset covers, is on our methodology page and reference tables.
What this site does not do
This site does not store any measurement you enter, does not diagnose a growth concern, and does not replace a pediatrician visit. It is a plotting tool against public reference data, nothing more.
How we make money
Right now, we do not. The percentile chart tool and every page are free and ungated, there is no email capture, and there is no paid tier.
