Height and Weight Centiles for a 13-Year-Old Girl
A 13-year-old girl with a height of 167 cm and weight of 58.19 kg falls at approximately the 90th centile for height and between the 75th-90th centiles for weight according to UK WHO growth charts.
Height Assessment
- A height of 167 cm for a 13-year-old girl is significantly above the average height for this age group, placing her at approximately the 90th centile on UK WHO growth charts 1
- This height indicates she is taller than approximately 90% of girls her age, suggesting she may be experiencing an early growth spurt or is constitutionally tall 2
- The normal height range for 13-year-old girls typically falls between 150-160 cm at the 50th centile, making her height notably above average 1
Weight Assessment
- The weight of 58.19 kg places this 13-year-old girl between the 75th and 90th centiles for her age group 1, 2
- For girls aged 13 years, the 50th centile weight is approximately 45-50 kg, while the 75th-90th centile range is around 55-60 kg, placing her weight in the upper-normal range 2
- This weight is proportionate to her height, indicating a balanced growth pattern 1
BMI Assessment
- Calculating her BMI: 58.19 kg ÷ (1.67 m)² = 20.9 kg/m², which falls within the normal range (between 18.5-24.99 kg/m²) for her age 1, 3
- A BMI of 20.9 kg/m² for a 13-year-old girl indicates appropriate weight for height without evidence of underweight or overweight status 1
- The normal BMI range for girls this age is approximately 18-22 kg/m², placing her in the normal range 2
Clinical Interpretation
- The combination of height at the 90th centile and weight between the 75th-90th centile suggests a healthy, proportional growth pattern 1, 2
- Growth velocity is as important as the absolute measurements; serial measurements over time provide more valuable information about growth patterns than single measurements 1
- Parental heights should be considered when interpreting growth charts to account for genetic potential 1
- The timing of puberty can significantly influence height and weight measurements at age 13, with early developers often being taller than their peers at this age 4, 5
Growth Monitoring Recommendations
- Continue regular growth monitoring every 6-12 months to ensure maintenance of appropriate growth trajectory 1
- Plot measurements on growth charts to visualize the growth pattern over time 1
- If there are concerns about rapid weight gain or disproportionate growth, more frequent monitoring may be warranted 6
- Consider evaluating nutritional intake and physical activity levels to support healthy growth during this critical developmental period 7
