Average Height for a 10-Year-Old Girl (2026): What's Normal and What Helps

The average height for a 10-year-old girl is about 4 feet 6 inches, or roughly 138 cm. That is the 50th percentile on the CDC growth chart. Most 10-year-old girls are between about 4 ft 2 in and 4 ft 11 in. For many girls, 10 is the last steady year before the growth spurt. What she eats and how she sleeps now sets her up for it.

Ten is a funny age for height. Some girls look like little kids. Others already look like preteens. Both are normal, and the gap can grow a lot over the next two years. Here is what the numbers mean and what you can do to help.

How tall is the average 10-year-old girl?

The average 10-year-old girl is about 4 feet 6 inches tall, or about 138 cm. That is the middle of the CDC growth chart that US pediatricians use.

Boys and girls are almost the same height at 10. The average 10-year-old boy is about 4 ft 7 in. Over the next couple of years, many girls will pull ahead for a while, because girls usually start their growth spurt first.

Average is not a goal. Half of girls her age are taller and half are shorter. A girl at the 20th percentile can be just as healthy as a girl at the 80th.

What is the normal height range for a 10-year-old girl?

Doctors use percentiles to show how a child compares with others her age. Here is the CDC chart for girls from 8 to 12, using exact birthdays.

The rows show steady growth. On average, girls grow about 5.1 cm from 9 to 10, roughly 2 inches. From 10 to 11, the average speeds up a little to about 6.0 cm. The big jump usually comes a bit later.

How much does a 10-year-old girl grow in a year?

Before the growth spurt, most girls grow at a fairly steady pace, about 2 inches a year on the CDC average. Some years are a little faster and some a little slower.

The pace matters more than the number. A girl who is short but grows steadily along her own line on the chart is usually doing fine. A girl whose growth slows down a lot is worth a doctor visit, even if she is tall.

The easiest way to track it is simple. Measure her against the same wall, without shoes, once or twice a year. Write the date next to the mark.

Is my 10-year-old daughter about to hit a growth spurt?

She might be. Nemours KidsHealth says girls usually start puberty between 8 and 13. The growth spurt comes between about 10 and 14, with the fastest growth about two years after puberty begins.

So at 10, some girls are already speeding up, and some will not start for a few more years. Early signs include breast buds, a bigger appetite, needing new shoes often, and body odor.

We explain what the next year often looks like in our guide to the average height for an 11-year-old girl.

How tall will my 10-year-old daughter be as an adult?

Her parents' heights are the best clue. Research suggests genes explain roughly 60 to 80 percent of adult height (Cleveland Clinic).

Doctors use the mid-parental height. Add the mother's and father's heights, take away 5 inches for a girl, and divide by 2. Mayo Clinic says there is no sure way to tell what a child's adult height will be, so treat the answer as a midpoint. We walk through examples in how tall will my daughter be.

Here is our honest view. Genetics sets the ceiling. Nutrition, sleep and health set the floor. At 10, she still has her biggest growth years ahead, so the floor really counts.

What should a 10-year-old girl eat to grow well?

Real food comes first. At 9, a child's needs for some nutrients jump, and many school-day diets do not keep up.

1. Calcium. The daily target rises from 1,000 mg to 1,300 mg at age 9 (NIH). NIH says many children and teens get less than they need. Milk, yogurt, cheese and fortified non-dairy milks are easy wins. See our list of non-dairy calcium foods if she skips dairy.
2. Vitamin D. It helps the body use calcium. The daily target is 600 IU. Our guide to vitamin D3 dosage for kids explains it by age.
3. Protein. Girls 9 to 13 need about 34 grams a day. Most get this from normal meals. See protein for growing kids.
4. Zinc and magnesium. Kids 9 to 13 need about 8 mg of zinc and 240 mg of magnesium a day. Beans, nuts, whole grains and meat help.
5. Iron. Girls 9 to 13 need 8 mg a day.

How much sleep does a 10-year-old need?

The CDC says children ages 6 to 12 need 9 to 12 hours of sleep a night. Many 10-year-olds get less, especially once phones and tablets show up.

Screens in bed are the biggest problem. Our guide to screen time before bed covers what the research found and what helps.

A simple routine works best: the same bedtime on school nights, a dark room and devices charging outside the bedroom.

What if my 10-year-old is a picky eater?

Picky eating is common at this age, and it often lines up with the years when growth needs rise. A girl who avoids dairy, fish and vegetables can miss calcium, vitamin D, zinc and omega-3.

Try small steps. Put one new food next to a favorite. Let her help pick and cook dinner once a week. Keep easy snacks like yogurt, cheese sticks and nuts in reach.

If gaps remain, a supplement can help fill them. Watch the sugar, though. The American Heart Association says kids should have less than 25 grams of added sugar a day. A daily gummy with 3 grams of sugar uses up 12 percent of that.

When should I talk to a doctor about my daughter's height?

KidsHealth says the most important question is whether a child keeps growing at a normal pace, not whether she matches her friends. Talk to her pediatrician if:

• She shows signs of puberty before age 8.
• Her height has crossed down through percentile lines on her chart.
• Her growth seems to have stalled over several months.
• She is much shorter than her parents' heights would predict.
• She has other symptoms, like tiredness, stomach problems or a poor appetite.

Her doctor can review her growth chart over time. If you are curious about the next few years, our guide to the average height for a 12-year-old girl shows what comes next.

Can vitamins make a 10-year-old girl taller?

No vitamin can push a child past her genes. What nutrients can do is make sure a real gap is not holding her back.

Research shows both sides. In a Thai study, children low in zinc who took zinc grew a little more than those who did not. But in a large Mongolian trial, weekly vitamin D for three years did not change the height of 8,851 children, even though most started out low. That is why we never promise inches.

If you compare brands, check sugar and printed doses first. We ranked the main options in our guide to the best growth gummies for kids.

Tallori Growth Gummies are made for ages 5 to 18, so a 10-year-old is right in the middle of the range. 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.

Tallori does not contain iron or protein, and it does not replace meals. Think of it as a backup for the nutrients that picky or busy kids often miss.
