Height Calculator
Convert height between centimeters and feet/inches, or predict your child's adult height using the mid-parental height formula.
About Height Calculation
The mid-parental height formula is a well-established pediatric tool that estimates a child's adult height based on parent heights. For boys: (father's height + mother's height + 5 inches) ÷ 2. For girls: (father's height + mother's height − 5 inches) ÷ 2. The ±2 inch range accounts for natural genetic variation. This is an estimate — nutrition, health conditions, and exercise also play significant roles. For more health metrics, try our BMI Calculator.
Height conversion is commonly needed when comparing international measurements. The US and UK use feet and inches, while most of the world uses centimeters. One inch equals exactly 2.54 centimeters, making the conversion straightforward: divide centimeters by 2.54 to get total inches, then divide by 12 to get feet. For clothing measurements that use similar conversions, our Bra Size Calculator also supports both unit systems.
