📏 Height Calculator
About the Height Calculator
Our online height calculator offers two practical functions: a unit converter and a child height predictor. Whether you need to switch between centimeters and feet/inches, or you're curious about your child's future stature, this free tool provides instant, accurate estimates.
📐 Height Converter (cm ↔ ft & in)
Simply enter a value and choose the input unit. The tool will convert instantly:
• Centimeters to feet and inches: divide by 2.54, then separate feet and inches.
• Feet to centimeters: multiply by 30.48.
• Feet & inches to centimeters: (feet × 30.48) + (inches × 2.54).
👶 Child Height Predictor
Based on the mid‑parental height method, a widely used pediatric guideline. Enter both parents' heights and select the child's gender.
Formula (in centimeters):
- Boy: (mother height + father height + 13) ÷ 2
- Girl: (mother height + father height − 13) ÷ 2
This gives the target genetic height, normally accurate within ±5 cm (±2 inches) for most children. Note: This is an estimate, not a medical diagnosis.
📊 Quick Reference
- 1 foot = 30.48 cm
- 1 inch = 2.54 cm
- 1 cm = 0.3937 inches

Yes, the converter works for everyone. You can also check predicted height for a child, but it's an estimate.
Why does the prediction use ±13 cm for gender difference?
Boys average about 13 cm (5 inches) taller than girls when combining parental heights.
