How to convert 171 cm to feet
There are 30.48 centimetres in one foot, so divide the height in centimetres by 30.48: 171 ÷ 30.48 = 5.610 feet. To get feet and inches instead, take the whole number of feet (5) and multiply the leftover 0.610 of a foot by 12, which gives 7.3 inches.

Is 171 cm tall or short?
That depends on age, sex and which group you compare with, so there is no single answer. Below, 171 cm is placed against two official US reference sources: the CDC growth charts for children and teenagers, and the national health survey (NHANES) for adults. A percentile is a ranking against a reference group, not a verdict on health: the 50th percentile means half the reference group are shorter.
Children and teenagers: 171 cm on the CDC growth charts
The CDC median (50th percentile) height for girls at age 20 is 163.3 cm, so 171 cm is above the median for girls at every age up to 20. The CDC median (50th percentile) height for boys reaches 171 cm at about age 15.2.
Where 171 cm falls at each age (percentile of the CDC stature-for-age chart, calculated with the LMS values CDC publishes):
| Age | Girls: 171 cm is | Boys: 171 cm is |
|---|---|---|
| 13 years | 98th | 97th |
| 14 years | 94th | 81st |
| 15 years | 92nd | 54th |
| 16 years | 90th | 36th |
| 17 years | 89th | 28th |
| 18 years | 89th | 24th |
| 19 years | 88th | 22nd |
Ages are birthdays (the CDC table row for the start of that year). The CDC charts describe US children. The NHS and UK health professionals use the UK-WHO growth charts from the Royal College of Paediatrics and Child Health, which can give slightly different results. If you are worried about a child’s growth, ask a GP or health visitor.
