Pediatric clinical reference

Length-based pediatric color ranges

Published conventional weight bands often associated with Broselow-style pediatric length systems. This page is a static educational comparison—not an official tape, calculator, or patient-specific dosing or equipment tool.

Use boundary: A clinical color zone is assigned from measured body length using a current institution-approved reference. Do not assign a zone from this weight table, and do not use these ranges to generate medication doses, shock energy, fluids, equipment sizes, or ventilator settings.

Conventional published color-to-weight bands

Pink6–7 kg
Red8–9 kg
Purple10–11 kg

The ranges above reflect commonly published nine-zone systems: Gray 3–5 kg, Pink 6–7 kg, Red 8–9 kg, Purple 10–11 kg, Yellow 12–14 kg, White 15–18 kg, Blue 19–23 kg, Orange 24–29 kg, and Green 30–36 kg. Tape editions and local systems may differ.

How to use this reference appropriately

  • Use a current institution-approved length-based tool to assign the color at the child’s heel; the static weight bands shown here do not assign a patient’s zone.
  • Use measured weight in kilograms when available for medication and energy calculations, according to the current institutional pediatric reference.
  • Verify the exact tape edition, local equipment cart, device manufacturer, medication concentration, and current PALS policy.
  • Do not reproduce or infer exact medication, equipment, or electrical-therapy values from this page.

Current safety notice
