Consult a pediatrician or healthcare provider for personalized growth assessment and concerns about your child's development.
Height is approximately 80% determined by genetics. The remaining 20% is influenced by environmental factors like nutrition and health.
Proper nutrition during childhood and adolescence is crucial for reaching genetic height potential. Focus on protein, calcium, and vitamin D.
Most growth occurs during puberty. Girls typically stop growing around 14-16 years, while boys continue until 16-18 years.
Choose from Height Converter, Height Predictor, Percentile Calculator, or Growth Chart based on your needs.
Select Metric (cm, meters) or Imperial (feet, inches) based on your preference.
Input your height or parent heights accurately. For predictor, enter both parents' heights and child's gender.
Get instant results with conversions, predictions, percentiles, or growth projections with detailed analysis.
Height prediction uses the mid-parental height method, a scientifically validated approach widely used by pediatricians and growth specialists. This method is based on genetic inheritance from both parents and has been validated through decades of clinical research and population studies.
For Boys:
[(Father's Height + Mother's Height) / 2] + 6.5 cm (or 2.5 inches)
For Girls:
[(Father's Height + Mother's Height) / 2] - 6.5 cm (or 2.5 inches)
Centimeters to Feet and Inches:
Feet = cm ÷ 30.48
Inches = (cm ÷ 2.54) mod 12
Feet and Inches to Centimeters:
cm = (feet × 30.48) + (inches × 2.54)
Meters to Feet:
feet = meters × 3.28084
| Centimeters | Feet & Inches | Meters |
|---|---|---|
| 150 cm | 4'11" | 1.50 m |
| 160 cm | 5'3" | 1.60 m |
| 170 cm | 5'7" | 1.70 m |
| 180 cm | 5'11" | 1.80 m |
| 190 cm | 6'3" | 1.90 m |
Rapid growth period. Babies grow approximately 25 cm (10 inches) in the first year and 12 cm (5 inches) in the second year.
Steady growth of about 5-7 cm (2-3 inches) per year. Growth rate is relatively consistent during this period.
Continued steady growth of 5-6 cm (2-2.5 inches) annually. Pre-puberty phase with predictable growth patterns.
Growth spurt begins. Girls grow 8-10 cm (3-4 inches) per year during peak growth. Most reach adult height by 14-16 years.
Growth spurt occurs later than girls. Boys grow 10-12 cm (4-5 inches) per year during peak. Continue growing until 16-18 years, sometimes into early 20s.
Growth slows significantly. Growth plates close, marking the end of height increase. Some individuals may gain 1-2 cm after 18.
The mid-parental height method used in our calculator is accurate within ±5 cm (2 inches) for most individuals, based on clinical pediatric research. This scientifically validated method accounts for approximately 80% of height variation, which is genetically determined. However, environmental factors like nutrition, health, and lifestyle can influence final adult height. The prediction is most reliable when both parents' heights are accurately measured. For personalized growth assessment, consult a pediatrician.
Girls typically stop growing around 14-16 years of age, usually 2-3 years after their first menstrual period. Boys continue growing until 16-18 years, sometimes into their early 20s. Growth plates (epiphyseal plates) close at the end of puberty, marking the end of height increase. A doctor can determine if growth plates are still open through X-rays.
To convert centimeters to feet and inches: Divide cm by 30.48 to get feet, then multiply the decimal part by 12 for inches. For example, 170 cm = 170 ÷ 30.48 = 5.577 feet = 5 feet 7 inches. Our calculator does this conversion instantly for you. To convert back: multiply feet by 30.48 and inches by 2.54, then add them together.
