A 13-year-old's height varies, but averages are around 156 cm (61.4 inches) for boys and 157-158 cm (61-62 inches) for girls, with normal ranges extending several inches above and below these averages, as growth depends on genetics and individual development. There's no single "should" height; some teens are tall, some are short, and most are within a broad normal range.
At this age, children are in adolescence, a phase where their bodies undergo rapid changes, including significant height increases. On average, a 13-year-old boy is around 5 feet 1 inch (155 cm), while a 13-year-old girl is approximately 5 feet 2 inches (157 cm).

Based on the above calculation, a weight of 60 kilograms would fall within the healthy weight range for a 13-year-old girl with a height of 5 feet 4 inches (1.6256 meters). Therefore, a weight of 60 kilograms can be considered within the healthy range.
Modern period
In the 150 years since the mid-nineteenth century, the average human height in industrialised countries has increased by up to 10 cm (3.9 in).
The average height for a 14-year-old can vary greatly depending on many factors such as genetics, nutrition, and gender. In general, the average height for a 14-year-old boy is about 1.63 meters (5 feet 4 inches) and for a 14-year-old girl is about 1.60 meters (5 feet 3 inches).
Changes in Boys
They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
The analysis revealed that taller individuals had shorter lifespans compared with their shorter peers (Table 1). In individuals who lived for at least 50 years, longevity was inversely correlated with adult height in men (r = –0.27, p < 0.001) and women (r = –0.25, p < 0.001).
Add the mother's height to the father's height in either inches or centimeters. Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls. Divide by 2.
But over the long term, a person's growth may be affected by not getting enough sleep. That's because growth hormone is normally released during sleep. If someone consistently gets too little sleep (known as "sleep deprivation"), growth hormone is suppressed. Lack of sleep also can affect other hormones.

Twin and family-based analyses estimate that between 30 and 90% of human height variation is determined by genetic factors, with most estimates towards the upper end of that range (Preece 1996; Silventoinen et al. 2000; Silventoinen et al.
Humans are still evolving, So, where will evolution take us in 1,000 years? Chances are we'll be taller. Humans have already seen a boom in height over the last 130 years. In 1880 the average American male was 5'7″ (170 cm).
