About this tool
The Right Dose Is Based on Weight, Not Age
The right acetaminophen (paracetamol) dose for a child is based on weight, not age. This free calculator uses the published pediatric weight-band dosing chart to show your child's single dose for the product you have at home — Children's Tylenol liquid (160 mg/5 mL), chewables, or international paracetamol syrups like Calpol (120 mg/5 mL and 250 mg/5 mL).
How it works:
- Enter your child's weight (pounds or kilograms)
- Select your child's age range
- Pick the product and concentration on your bottle or box
- Get the dose in mL, teaspoons, or tablets — plus a printable chart for the fridge
The result also shows how long to wait between doses (every 4–6 hours) and the maximum number of doses in 24 hours (5). Always use the dosing syringe or cup that comes with the medicine, and never combine it with other medicines that also contain acetaminophen/paracetamol.
Tip: The Fever Whiz app keeps a shared dose log with a built-in timer, so every caregiver knows exactly when the next dose window opens — even at 2 AM.
For educational and logging purposes only. General guidance based on published pediatric dosing tables. Always confirm dose decisions with your pediatrician.
