Height Predictor


If you are wondering how tall you'll be when you finish growing then our height predictor can help. It uses the Khamis Roche calculation method for children over four years old.

If you're younger than four then we estimate using your parents' heights (with the Mid-Parental Height Formula). For both methods, predict your adult height by simply entering the following details below: 

  • your age
  • your current height and weight
  • your parents' heights

While generally accurate, everyone is different. Ultimately, your final adult height can be influenced by factors such as nutrition, physical activity, and the timing of puberty

Height prediction involves multiple factors including genetics, nutrition, and overall health. This calculator uses the well-established mid-parental height method for younger ages and Khamis Roche for older ones, combined with current growth data to estimate adult height. 

Understanding Future Height

Genetics plays the dominant role in determining a child's height, accounting for approximately 80% of height potential. However, several key environmental factors work together to influence how tall you should be as an adult

Environmental Factors

These environmental factors contribute up to 20-40% to final height. These include:

  • Nutrition during childhood and adolescence
  • Overall health and medical conditions
  • Sleep quality and duration
  • Physical activity levels
  • Socioeconomic conditions

Genetic Inheritance

Conversely 60-80% of height then is primarily inherited through DNA, with multiple genes working together to determine yours or your child's growth potential. This explains why children often reach similar heights to their biological parents, though siblings can vary significantly in height.

Growth and Development

Critical Growth Periods
Growth patterns typically follow predictable stages, with significant growth occurring during:

  • Early childhood
  • Pre-puberty
  • Adolescent growth spurt

Health Influences
Several health-related factors can impact growth:

  • Growth hormone levels
  • Thyroid function
  • Overall nutritional status
  • Presence of chronic conditions

Optimizing Growth Potential

To support healthy growth development:

  • Ensure proper nutrition with adequate protein intake
  • Maintain regular physical activity
  • Establish good sleep habits
  • Monitor growth with regular health check-ups

Remember that while genetics largely determine height potential, providing optimal environmental conditions helps ensure your child reaches their full height potential.
