Average Height for a 16-Year-Old Girl (2026): Is She Done Growing?

The average height for a 16-year-old girl is about 5 feet 4 inches, or roughly 163 cm. That is the middle of the CDC growth chart, the 50th percentile. Most 16-year-old girls are between about 5 ft 0 in and 5 ft 8 in. By 16, most girls are at or very close to their adult height. So the real question is not how tall she is today. It is whether she is done growing.

If you are reading this, you may have a daughter who feels short next to her friends. Or she may be the tall one and wonders when it stops. Both are normal. This guide gives you the real numbers, what they mean, and what a parent can still do at 16.

How tall is the average 16-year-old girl?

The average 16-year-old girl is about 5 feet 4 inches tall. In centimeters, that is about 163 cm. This number comes from the CDC growth charts that pediatricians use in the United States.

Average means the middle. Half of girls this age are taller. Half are shorter. Average is not a goal, and it is not a grade. A girl who is 5 feet 1 inch can be just as healthy as a girl who is 5 feet 7 inches.

Here is something many parents do not expect. The average girl barely grows after 15. On the CDC chart, the average line goes up only about 0.7 cm from 15 to 16. That is less than half an inch. From 16 to 18 it rises about 0.6 cm more. For most girls, the big growth years are already over.

What is the normal height range for a 16-year-old girl?

Doctors read height as a percentile, not one number. A percentile tells you how a girl compares with 100 girls her age. At the 5th percentile, she is taller than 5 of them. At the 95th, she is taller than 95.

Here is where girls land on the CDC chart from 14 to 18. The ages are exact birthdays. Your daughter's own number will move a little as the months pass.

Look at how flat the rows get. From 16 to 18, the 5th, 50th and 95th percentile lines hardly move. That flat line is the chart showing you that growth is ending for most girls.

Is a 16-year-old girl still growing?

Most are close to done. Nemours KidsHealth explains the usual order of events for girls. The growth spurt comes first, between about ages 10 and 14. Periods usually start after the fastest growth, at about 12 and a half on average. After the first period, most girls grow about 1 or 2 more inches. Most reach their adult height by about 14 or 15.

That means a girl who got her first period at 12 has probably finished growing by 16. A girl who started puberty late may still have a little left. Late starters are common, and they often catch up.

A simple clue is her shoe size and her clothes. If her jeans have fit the same for a year, she has likely stopped. If she still outgrows them every few months, she may have some growth left.

How much taller will she get after 16?

For most girls, very little. The CDC average adds less than half an inch from 16 to 18. Some girls will add nothing. A few late starters will add an inch or so.

Her parents' heights tell you more than any chart. Doctors use a simple rule called the mid-parental height. Add the mother's and father's heights, take away 5 inches for a girl, and divide by 2. We walk through it step by step in how tall will my daughter be.

Mayo Clinic is clear that no formula is a sure thing. The answer is a midpoint, not a promise. Still, it is a better guide than any number you will find online.

Why are 16-year-old boys so much taller than girls?

Timing. On the CDC chart, the average 16-year-old boy is about 5 ft 8 in. That is about 11 cm taller than the average girl. But girls were taller first.

Girls start their growth spurt about two years before boys. So at 11 and 12, many girls stand taller than the boys in their class. Then boys catch up and pass them. At 16, most girls are done, while many boys are still growing. You can compare with our guide to the average height for a 16-year-old boy.

What decides how tall a 16-year-old girl will be?

Genes come first. Research suggests genetics explains roughly 60 to 80 percent of adult height (Cleveland Clinic). The rest is shaped by nutrition, sleep, and health during the growing years.

Here is our honest view. Genetics sets the ceiling. Nutrition, sleep and health set the floor. Good habits help a child reach her own range. They do not change the range. At 16, most of that work has already happened.

Some things can slow growth. Long-term illness, very low food intake, and some medicines can do it. If a girl stops growing early and much shorter than her family, a doctor should look at it.

When should you talk to a doctor about her height?

KidsHealth says the key question is not whether a teen is as tall as her friends. It is whether she keeps growing at a normal pace. A growth rate that was normal and then suddenly flattens is the thing to watch.

Talk to her pediatrician if you notice any of these:

• She has not started puberty by about 13.
• Her height has dropped across percentile lines, not just sat low on one.
• She is much shorter than her parents' heights would predict.
• She has other signs, like being very tired, losing weight, or missing periods.

A doctor may look at her growth chart over time. Sometimes they order a hand X-ray to check bone age. That shows whether her growth plates are still open. You can read more in our guide on when growth plates close.

What does a 16-year-old girl need for healthy bones?

Even when height is done, bones are still getting stronger. The teen years are a big bone-building time. Habits she keeps now help her bones for years to come.

1. Calcium. Teens ages 9 to 18 need 1,300 mg a day (NIH Office of Dietary Supplements). NIH says many children and teens get less than that. See our guide to how much calcium kids need.
2. Iron. Teen girls need 15 mg a day, more than teen boys, because periods use up iron (NIH). Read our guide to iron for growing kids.
3. Vitamin D. It helps the body use calcium. The daily target for teens is 600 IU.
4. Sleep. The CDC says teens 13 to 17 need 8 to 10 hours a night. Phones out of the bedroom help.
5. Movement. Running, jumping and sports help build strong bones. The CDC suggests 60 minutes of activity a day for kids and teens.

Can vitamins help a 16-year-old girl grow?

Not in the way the ads suggest. No vitamin can make a teen taller once her growth plates close. And for a teen who still has a little growth left, vitamins only help if they fill a real gap.

Here is a fair example from the research. A large trial in Mongolia gave 8,851 children weekly vitamin D for three years. Most of them were low in vitamin D at the start. Their height did not change. That is why we never promise inches.

What a good supplement can do is cover the gaps a busy or picky teen leaves in her diet. That matters for bones, energy and focus. It is not a height trick.

Does sugar matter in a teen vitamin?

Yes. The American Heart Association says kids and teens should have less than 25 grams of added sugar a day. A gummy with 3 grams of sugar uses up 12 percent of that before breakfast. Taken every day, that adds up.

If you compare brands, look at the label, not the front of the bag. We ranked the main options by sugar and real doses in our guide to the best growth gummies for kids.

Tallori Growth Gummies were made for the growing years, ages 5 to 18. They have zero added sugar and are sweetened with monk fruit and xylitol. All 7 vitamin and mineral doses are printed on the label: vitamin C, vitamin D3, vitamin K2 as MK-7, calcium, magnesium, zinc and algae DHA. The botanicals sit in a 112.4mg Tallori Clean Growth Blend, and those single doses are not printed.

One honest note for teen girls. Tallori does not contain iron. If your daughter is low in iron, her doctor can test her and suggest the right amount. A gummy that fits ages 5 to 18 is the wrong place for a fixed iron dose.
