Pediatrics Calculators

20 Pediatrics calculators with educational summaries for clinical reference.

What this collection covers

Pediatric tools are organized around age-specific growth, dosing, fluids, respiratory illness, trauma, sepsis, jaundice, and neurologic assessment. Pediatric measurements change rapidly with age, so the applicable reference and exact age are central to interpretation.

How to choose a tool

Confirm age, weight, gestational age when relevant, developmental context, and the reference standard before using a pediatric calculator. Use the calculator page to check whether a tool is for screening, triage, monitoring, or a treatment calculation.

Safe interpretation

Children can deteriorate quickly and a score may understate risk when data are missing or the child is outside the validation population. Verify every dose and fluid recommendation against a current pediatric protocol and qualified clinician review.
