How accurate is a height calculator?

Height calculators provide estimates based on established formulas such as Mid-Parental and Khamis-Roche methods. They are not exact predictions and should not replace professional medical advice.

What is the Mid-Parental height formula?

The Mid-Parental formula estimates adult height using parents' heights. For boys: (Father + Mother + 13 cm) divided by 2. For girls: (Father + Mother − 13 cm) divided by 2.

What age is the Khamis-Roche method used?

The Khamis-Roche method is typically used for children aged 7 to 14 years and incorporates current height, weight, and parental heights.

Does BMI affect height prediction?

BMI does not directly determine adult height but may be included in prediction formulas like Khamis-Roche as part of growth assessment.
