What to expect at 16 Years 9 Months
By 16, most girls have reached close to their adult height, having completed the majority of their pubertal growth spurt. Some girls continue to gain small amounts of height into their late teens. Final adult height is primarily determined by genetics, with nutrition and health during the growth years playing a supporting role.
Puberty and the growth spurt
For teenage girls, the pubertal growth spurt is closely linked to the onset of menstruation. Girls who have not started their periods by age 16 should be reviewed by a GP. Adequate caloric intake is especially important during puberty - significant energy restriction can delay or slow the pubertal growth spurt and affect bone density accrual at a critical time.
Bone health during peak growth
Weight-bearing physical activity such as running, gymnastics, and dancing supports healthy bone density during the years of peak bone accrual in adolescence. Calcium requirements are highest between ages 9-18 (1,300 mg per day). Vitamin D supports calcium absorption - particularly important for those with limited sun exposure.
Frequently asked questions
Is it normal to be shorter than friends at this age?
Yes - the timing of puberty varies considerably between individuals. A teenager who is shorter than their peers may simply have a later puberty onset and will often experience their growth spurt after those who developed earlier. If there are no other signs of puberty by age 14 in girls or 15 in boys, it is worth discussing with a GP.
When do girls stop growing taller?
Most girls reach their final adult height approximately 2-3 years after the start of menstruation, typically between ages 15 and 17. Some girls continue to gain small amounts of height into their late teens, but the majority of pubertal height gain is complete by around 16.
When do boys stop growing taller?
Boys generally stop growing in height between ages 17 and 20, with late-maturing boys sometimes continuing to grow into their early twenties. The growth spurt in boys typically peaks around ages 13-15, later than in girls. Boys who are late developers will often catch up with and eventually surpass peers who grew earlier.
Data sources and methodology
The percentile ranges on this page are drawn from CDC growth chart data from the National Center for Health Statistics and WHO Child Growth Standards (for children under 5). CDC data published May 30, 2000, with 2022 extended BMI tables. Percentiles are modelled using the LMS method (Box-Cox transformation), which accounts for the skewed distribution of measurements at each age. All measurements are given in metric units with imperial equivalents.
These percentile ranges provide a population-level reference. A paediatrician or family doctor can give context specific to the individual's own growth trajectory.
