Where growth stands at 17

Most girls have finished growing.

The average girl at 17 has reached 100% of the average adult woman's height in the same charts (5′4½″). A girl who starts puberty late will be below average now and often catches up later; an early developer may be tall now and finish close to average.

Is my child's height normal?

Doctors look less at one measurement than at the pattern: a child who stays near the same percentile year after year is growing normally, whatever that percentile is. Talk to your doctor if your child drops across percentile lines, grows much slower than classmates, or is far below what both parents' heights predict.

Boys vs. girls at 17

Questions people ask

How tall should a 17-year-old girl be?

There is no single "should". The average is 162.9 cm (5′4″), and anything from about 5′0″ to 5′8½″ is within the normal range. What matters more is growing steadily along the same percentile line over time.

Is 5′6″ tall for a 17-year-old girl?

Yes, a bit. 5′6″ is around the 75th percentile: taller than about 3 in 4 girls the same age.

What is short for a 17-year-old girl?

Below about 5′0″ (152 cm) is under the 5th percentile. Many children there are simply small like their parents or late developers, but it is worth a check with a doctor, especially if growth has slowed.

How much taller will a 17-year-old girl get?

Usually very little: most girls have reached adult height by 17.
