1. The normal height range for a 14-year-old girl is approximately 151.3 to 165.9 centimeters.2. The corresponding weight range is roughly 39.55 to 58.88 kilograms.3. At this age, girls exhibit a wide range of heights and weights due to individual differences, innate genetic factors, and various lifestyle influences.4. Genetics plays a significant role in determining height as a先天 factor.5. Factors acquired later in life, such as nutritional intake, sleep quality, and physical exercise, also affect a child's growth in height and weight.6. Puberty typically begins in girls aged 9 to 11, marking the onset of the second period of rapid growth, which lasts for about 2 to 3 years.7. During this period, girls may experience an increase in height of about 8 to 9 centimeters per year and a weight gain of approximately 25 to 30 kilograms.8. This stage is crucial for height and weight development, and if there is delayed growth, it is important to seek medical attention early to determine if there are any underlying health issues, as height development at this stage can influence final height.9. However, individual variations are inevitable, so it is also necessary to assess whether these fall within the normal range.10. If the measurements are lower than normal, it is advisable to conduct a medical examination to identify any potential health concerns.
