The paediatric dose calculator and child growth calculator below give instant, weight-based estimates in plain language — with a clear reminder to confirm everything with your doctor or pharmacist.
Giving medicine to a child shouldn't feel like a maths exam. PaediCalc brings a paediatric dose calculator and a child growth calculator together in one free tool, built for busy parents and caregivers anywhere in the world. Enter a few details and get instant, plain-language results.
Children's medicines are dosed by weight, so that's where every calculation starts. Whether you're checking kids medication dosing before a fever dose or comparing your toddler's height with typical growth curves, results appear in seconds — no forms, no sign-up.
Just as important is what PaediCalc isn't: a replacement for your pediatrician or pharmacist. Treat every estimate as a starting point — the medicine label and the professional who prescribed it always have the final word.
Five-second answers, honest limitations, and units that make sense wherever you live.
Enter your child's weight once and see pediatric medication dosage by weight worked out instantly, for a single dose and across a full day. The same simplicity makes it a dependable infant dosing calculator for the earliest months, when getting the numbers right matters most.
The child growth calculator turns age, sex, height and weight into an easy-to-read percentile view, so a check-up conversation starts from a picture rather than a spreadsheet. Spot the trend first, then confirm it with your pediatrician's measurements.
PaediCalc is mobile-friendly, so it works at the pharmacy counter or 3 a.m. in the nursery. Switch freely between kg/lb and cm/in, and rely on clear safety disclaimers on every screen — because a confident estimate should never become a confident mistake.
Dosing questions don't wait for a laptop, and neither should you. The pocket-ready pediatric calculator app keeps both the dose and growth calculators offline and one tap away — at the pharmacy counter, on holiday, or during a 3 a.m. fever. Download PaediCalc free and carry a calmer medicine cabinet in your pocket.
No. PaediCalc is an educational tool that produces estimates from the numbers you enter. It never replaces your pediatrician, pharmacist, or the instructions on the medicine. When the calculator and your prescription label disagree, trust the label — and ask a professional to explain the difference.
It's an approximation. The percentile range depends entirely on the age, sex, height and weight you enter, and home measurements (shoes on, different scales, a wriggly toddler) add error. Use the result as a rough guide between check-ups, and treat your pediatrician's measurements as the ones worth tracking over time.
Yes. The infant dosing calculator is weight-based precisely because baby doses depend so heavily on weight. That said, infant dosing leaves little room for error, so always confirm a baby's dose with your doctor or pharmacist first. If your baby was born early, ask how corrected age affects growth results.
No. You don't need an account, and we don't ask for your child's name or contact details. The calculators work in the moment, and your entries aren't saved once you leave the page — so you can check a dose without creating a data trail.
