At age 14, many boys are still in the middle of a major growth period, so there is no single height that every teenager should reach. According to the World Health Organization (WHO) 2007 growth reference, the median height for a 14-year-old boy at exactly 14 years is about 163.2 cm (5 feet 4.3 inches). By age 14 years 11 months, the median rises to about 168.5 cm (5 feet 6.3 inches). That means the average height for 14 year old boy can change noticeably depending on his exact age in months and where he is in puberty.
Height differences at this age are completely normal. Some boys experience their growth spurt early, while others develop later and may gain substantial height during the next few years. Growth charts are therefore more useful than comparing one teenager with classmates or friends.
What Is the Average Height for 14 Year Old Boy?
The simplest answer is that the average height for 14 year old boy is around 163 cm to 164 cm (about 5 feet 4 inches) at exactly age 14, using the WHO reference median.
However, “14 years old” covers an entire 12-month period. A boy who has just turned 14 is not expected to have the same height as a boy who is almost 15.
The WHO height-for-age reference gives these median measurements:
| Age | Median height | Approx. height in feet |
|---|---|---|
| 13 years | 156.0 cm | 5 ft 1.4 in |
| 13 years 6 months | 159.7 cm | 5 ft 2.9 in |
| 14 years | 163.2 cm | 5 ft 4.3 in |
| 14 years 6 months | 166.3 cm | 5 ft 5.5 in |
| 15 years | 169.0 cm | 5 ft 6.5 in |
| 16 years | 172.9 cm | 5 ft 8.1 in |
| 17 years | 175.2 cm | 5 ft 9.0 in |
| 18 years | 176.1 cm | 5 ft 9.3 in |
These figures come from the WHO 5–19-year growth reference for boys.
So if you are searching for the average height for 14 year old boy, approximately 163 cm (5’4″) is a useful reference point for a boy who has just reached his 14th birthday.
But it should not be treated as a target.
How Tall Is a 14-Year-Old Boy Supposed to Be?
There is no height that a 14-year-old boy is “supposed” to be.
Growth is highly individual, especially during puberty. Two healthy 14-year-old boys can have very different heights and still follow perfectly normal growth patterns.
For example, the WHO reference at exactly 14 years places the 25th percentile at about 158.0 cm, the 50th percentile at 163.2 cm, and the 75th percentile at 168.4 cm. The broader reference also shows that boys can fall considerably above or below those values.
This is why pediatricians generally look at growth over time, rather than judging a teenager from one measurement.
A boy who is 155 cm at 14 may be shorter than the median but continue growing rapidly. Another boy who is 170 cm may already be closer to the end of his major growth spurt.
A Useful Way to Think About Height
Instead of asking, “Is my height normal?” consider three questions:
- Is height increasing over time?
- Is growth following a reasonably consistent pattern?
- Has puberty started and progressed normally?
- Is the teenager generally healthy and well nourished?
- Is his height reasonably consistent with his family growth pattern?
These questions provide much more useful information than comparing height with a single friend.
The CDC likewise explains that stature-for-age is used to assess linear growth relative to age and that growth charts are tools for tracking development rather than standalone diagnostic tests.
Average Height for 14 Year Old Boy by Exact Age
One of the most important details about teenage height is the number of months since the child’s birthday.
A 14-year-old can technically be anywhere from 14 years 0 months to 14 years 11 months old. During that period, the WHO median increases from approximately 163.2 cm to 168.5 cm.
Here is a closer look:
| Exact age | Median height | Feet and inches |
|---|---|---|
| 14 years 0 months | 163.2 cm | 5’4.3″ |
| 14 years 1 month | 163.7 cm | 5’4.5″ |
| 14 years 2 months | 164.3 cm | 5’4.7″ |
| 14 years 3 months | 164.8 cm | 5’5.0″ |
| 14 years 4 months | 165.3 cm | 5’5.1″ |
| 14 years 5 months | 165.8 cm | 5’5.3″ |
| 14 years 6 months | 166.3 cm | 5’5.5″ |
| 14 years 7 months | 166.8 cm | 5’5.7″ |
| 14 years 8 months | 167.2 cm | 5’5.8″ |
| 14 years 9 months | 167.7 cm | 5’6.0″ |
| 14 years 10 months | 168.1 cm | 5’6.2″ |
| 14 years 11 months | 168.5 cm | 5’6.3″ |
These are reference medians, not minimum or maximum heights.
This explains why two websites may give slightly different answers when someone searches for the average height for 14 year old boy. One source may use the exact 14-year mark, while another may use a broader age category.
Average Height for 14 Year Old Boy in Feet and Inches
For readers who prefer imperial measurements, the median height at exactly 14 years is approximately:
163.2 cm = 5 feet 4.3 inches
In everyday conversation, that can be rounded to approximately 5 feet 4 inches.
At 14 years 6 months, the median is approximately:
166.3 cm = 5 feet 5.5 inches
And by the 15th birthday, the median is approximately:
169.0 cm = 5 feet 6.5 inches.
Small differences in reported measurements are normal. Height can also vary during the day because the spine becomes slightly compressed while standing and walking.
For consistent tracking, height should ideally be measured under similar conditions each time.
Average Height for 14 Year Old Boy Compared With Percentiles
Percentiles are one of the best ways to understand teenage height.
Imagine 100 boys of the same age lined up from shortest to tallest. A boy around the 50th percentile would be near the middle of that group.
At exactly 14 years, the WHO reference gives approximately:
| Percentile | Height |
|---|---|
| 5th | 150.5 cm |
| 15th | 155.2 cm |
| 25th | 158.0 cm |
| 50th | 163.2 cm |
| 75th | 168.4 cm |
| 85th | 171.2 cm |
| 95th | 175.8 cm |
| 97th | 177.6 cm |
| 99th | 181.1 cm |
These numbers demonstrate just how wide normal variation can be.
A teenager does not need to be close to the 50th percentile to be healthy.
Being at the 25th percentile, for example, simply means the measurement is lower than the median. It does not automatically mean something is wrong.
Average Height for 14 Year Old Boy vs Other Ages
Looking at nearby ages helps put the number into context.
| Age | Approx. median height |
|---|---|
| 12 | 149.1 cm / 4’10.7″ |
| 13 | 156.0 cm / 5’1.4″ |
| 14 | 163.2 cm / 5’4.3″ |
| 15 | 169.0 cm / 5’6.5″ |
| 16 | 172.9 cm / 5’8.1″ |
| 17 | 175.2 cm / 5’9.0″ |
| 18 | 176.1 cm / 5’9.3″ |
The pattern shows why judging a 14-year-old based on adult height expectations can be misleading.
The median increases particularly noticeably during the teenage years before gradually leveling off.
Why Are Some 14-Year-Old Boys Much Taller or Shorter?
The main reason is that adolescence does not happen according to one universal timetable.
Genetics, puberty timing, nutrition, overall health, and other biological factors can all influence growth.
Genetics
Heredity is one of the strongest influences on eventual height.
Tall parents tend, on average, to have taller children, while shorter parents tend to have shorter children. However, genetics does not work like a simple copy-and-paste system.
A teenager can resemble one side of the family more strongly than the other, and siblings can also end up with noticeably different adult heights.
The American Academy of Pediatrics notes that heredity has a major influence on a child’s growth and ultimate height.
Puberty Timing
Puberty timing is especially important at age 14.
Some boys enter puberty earlier and experience their growth spurt sooner. Others develop later and may remain shorter for a while before catching up.
According to the American Academy of Pediatrics, boys generally enter puberty about a year later than girls, and the peak growth period for boys occurs roughly two years after puberty begins.
That means two boys who are both 14 can be at completely different stages of physical development.
Nutrition
Adequate nutrition supports normal growth.
A teenager needs sufficient energy and nutrients for the body to build bone, muscle, blood, and other tissues. A balanced diet containing adequate protein, calcium, vitamin D, fruits, vegetables, whole grains, and other nutrient-rich foods supports overall health.
However, eating extra food or taking unnecessary supplements does not guarantee extra height.
Genetics and puberty timing remain major influences.
Sleep and Lifestyle
Sleep is another important part of healthy adolescent development.
A teenager’s body undergoes substantial physical and hormonal changes during sleep. Regular physical activity, adequate rest, and a balanced lifestyle can support general health during the growing years.
Lifestyle cannot override genetics, but poor health, severe nutritional problems, or certain medical conditions can interfere with normal growth.
Average Height for 14 Year Old Boy During Puberty
Puberty is one of the biggest reasons height varies so dramatically at 14.
For some boys, the major growth spurt is already underway. For others, it may be approaching or just beginning.
The American Academy of Pediatrics explains that boys typically have their peak growth period around two years after puberty begins.
This means a 14-year-old boy who has recently entered puberty may have considerably more growth ahead.
A boy who began puberty earlier may already have passed much of his fastest growth.
Neither situation automatically indicates a problem.
What Does a Growth Spurt Look Like?
During a growth spurt, a teenager may:
- Gain several centimeters in a relatively short period
- Notice that trousers and shoes become too small
- Become temporarily awkward or less coordinated
- Develop broader shoulders
- Gain muscle more easily as puberty progresses
- Experience other normal pubertal changes
Growth does not necessarily happen at a perfectly steady rate. The American Academy of Pediatrics notes that children and adolescents can grow in spurts, with periods of faster and slower growth.
Average Height for 14 Year Old Boy Growth Timeline
There is no single growth timeline that applies to every teenager, but the WHO median provides a useful population-level reference.
| Age | WHO median height |
|---|---|
| 10 | 137.8 cm |
| 11 | 143.1 cm |
| 12 | 149.1 cm |
| 13 | 156.0 cm |
| 14 | 163.2 cm |
| 15 | 169.0 cm |
| 16 | 172.9 cm |
| 17 | 175.2 cm |
| 18 | 176.1 cm |
The important point is not that every boy should follow this exact sequence. Instead, it demonstrates the general pattern of increasing height during adolescence.
Some boys will grow earlier, some later, and some will remain consistently above or below the median throughout childhood.
Can a 14-Year-Old Boy Still Grow Taller?
Yes. Many 14-year-old boys still have significant growth ahead.
The amount of additional growth depends heavily on puberty timing and skeletal maturity.
A boy who is late in puberty may have considerably more growth remaining than a boy who is nearing the end of puberty.
The WHO reference itself shows that the median continues increasing from approximately 163.2 cm at age 14 to 169.0 cm at age 15, 172.9 cm at 16, and 175.2 cm at 17.
This does not mean every 14-year-old will gain exactly those amounts.
It simply demonstrates that population-level growth continues well beyond the 14th birthday.
How Much Can a 14-Year-Old Boy Grow?
There is no reliable single number that applies to every 14-year-old.
One teenager might grow only a few centimeters after turning 14, while another may grow considerably more.
Puberty stage matters enormously.
The American Academy of Pediatrics explains that boys’ growth spurts vary in timing and that individual differences in development can produce substantial differences between children of the same age.
Therefore, a current height measurement is only one piece of information.
A better assessment looks at:
- Previous height measurements
- Growth velocity
- Puberty stage
- Family heights
- General health
- Nutrition and lifestyle
- Medical history when relevant
Average Height for 14 Year Old Boy vs Adult Height
It is tempting to compare a 14-year-old with the average adult man, but this can create unnecessary concern.
A 14-year-old is still developing.
The WHO reference median increases from 163.2 cm at age 14 to approximately 176.1 cm at age 18.
That difference illustrates why an adolescent’s current height cannot be used as a direct substitute for adult height.
For example, being 160 cm at 14 does not mean a boy will necessarily remain 160 cm as an adult.
Likewise, being 175 cm at 14 does not guarantee that he will stop growing there.
How to Estimate Future Height
Parents and teenagers often wonder whether current height can predict adult height.
There are several methods, but none can guarantee the final result.
One commonly used approach considers the heights of both parents. Pediatricians may also examine a child’s growth history and, when appropriate, assess bone age.
The American Academy of Pediatrics explains that bone age, determined through an X-ray of the hand, can provide a more useful assessment of remaining growth than simply guessing from current height.
Home formulas should therefore be viewed as rough estimates rather than promises.
Why Family Height Matters
Family height can provide useful context.
If both parents are relatively tall, a teenager may be expected to have a higher adult height than someone with two shorter parents.
But family patterns are not guarantees. Genetic variation means individual outcomes can differ.
How to Measure a 14-Year-Old Boy’s Height Correctly
Accurate measurement matters when tracking growth.
For a consistent measurement:
- Remove shoes.
- Stand on a hard, level floor.
- Keep heels close to the wall.
- Keep the body upright.
- Look straight ahead.
- Keep the head in a neutral position.
- Use a flat object against the top of the head.
- Record the measurement in centimeters or inches.
- Measure under similar conditions when comparing results.
The goal is consistency rather than obsessing over tiny differences.
A difference of a few millimeters between measurements is usually less meaningful than the overall growth trend across months.
Is 5 Feet Tall Short for a 14-Year-Old Boy?
At exactly 14 years, 5 feet is below the WHO median.
Five feet is approximately 152.4 cm, while the WHO median at 14 years is approximately 163.2 cm.
However, that comparison alone cannot determine whether a particular teenager is healthy.
Puberty timing is crucial.
A 14-year-old who has not yet experienced his main growth spurt may grow considerably over the next several years.
If a teenager is significantly shorter than peers and there are concerns about his growth pattern, discussing the situation with a pediatrician is more useful than relying on internet averages.
Is 5’5″ Tall for a 14-Year-Old Boy?
Five feet five inches is approximately 165 cm.
That is slightly above the WHO median for a boy at exactly 14 years, which is about 163.2 cm.
But again, being above or below the median is not automatically better or worse.
A healthy growth pattern matters more than reaching a particular number.
Is 6 Feet Tall for a 14-Year-Old Boy?
Six feet is approximately 183 cm, which is substantially above the WHO median for a 14-year-old.
At exactly 14 years, the WHO 99th percentile is approximately 181.1 cm, so 183 cm would be above that reference percentile.
A very tall teenager may simply have inherited tall stature or be experiencing puberty earlier than peers. In less common situations, unusually rapid or extreme growth can have medical causes.
The American Academy of Pediatrics notes that unusually tall growth can sometimes be associated with early puberty or, more rarely, excess growth hormone production.
When Should Parents Be Concerned About Height?
Most differences in teenage height are normal.
Still, growth deserves medical attention when there is a persistent or unusual pattern.
It may be worth discussing growth with a pediatrician if:
- Height appears to stop increasing for an extended period.
- A child drops significantly across growth percentiles.
- Growth is unusually rapid.
- Puberty appears substantially delayed.
- There are other concerning symptoms.
- A teenager is far outside expected family growth patterns.
- Parents have ongoing concerns about development.
The American Academy of Pediatrics notes that boys who show no signs of puberty by age 14 should be evaluated.
This does not mean every shorter 14-year-old has a medical problem. Some healthy boys simply mature later.
WHO vs CDC Growth Charts
You may see different numbers online because different growth references are used.
The WHO 2007 reference covers children and adolescents from 5 through 19 years and provides height-for-age percentiles for boys and girls. WHO describes these references as useful for global and national growth monitoring.
The CDC growth charts, meanwhile, are based on U.S. reference data and cover children and adolescents from ages 2 to 20 years. CDC describes these charts as tools for tracking growth in U.S. children and adolescents.
Neither should be interpreted as a universal requirement that every teenager must match.
For an individual child, healthcare professionals generally care more about the child’s growth trajectory than about one isolated percentile.
Interesting Facts About the Average Height for 14 Year Old Boy
Here are several facts that make teenage height easier to understand:
1. Age in months matters
A 14-year-old who has just turned 14 can have a different expected median height from someone nearly 15.
2. Puberty changes the picture
Two boys of the same age can be at very different stages of puberty.
3. Growth is not perfectly linear
Teenagers often grow in spurts rather than gaining exactly the same amount every month.
4. The median is not a goal
Being at the 50th percentile does not make someone healthier than being at the 25th or 75th percentile.
5. Genetics matters greatly
Family height is one of the strongest influences on eventual stature.
6. Fourteen is not necessarily the end of growth
The WHO reference shows continued median height increases after age 14.
7. A single measurement tells only part of the story
Tracking height over time gives much more information about growth.
Frequently Asked Questions
What is the average height for 14 year old boy?
The WHO median height for a boy at exactly 14 years is approximately 163.2 cm, or about 5 feet 4.3 inches. The median increases throughout the 14th year, reaching approximately 168.5 cm by 14 years 11 months.
What is the average height for 14 year old boy in feet?
At exactly age 14, the WHO median is approximately 5 feet 4 inches. Because growth continues throughout the year, a boy who is nearly 15 may have a higher expected median height.
Is 5’4″ short for a 14-year-old boy?
Five feet four inches is approximately 162.6 cm, which is very close to the WHO median of 163.2 cm at exactly age 14. Therefore, it is around the middle of the reference distribution at that exact age.
Is 5’5″ tall for a 14-year-old boy?
Five feet five inches is approximately 165 cm, which is slightly above the WHO median for a boy who has just turned 14. However, it is still within the ordinary range of variation.
Can a 14-year-old boy still grow taller?
Yes. Many boys continue growing after 14. The amount of remaining growth depends largely on puberty timing, genetics, and skeletal maturity. The WHO reference shows that median height continues increasing through the later teenage years.
What affects a boy’s height at age 14?
Genetics and puberty timing are major influences. Nutrition, overall health, sleep, and other environmental and biological factors also contribute to healthy development.
How do I know whether my son’s height is normal?
Look at his growth pattern over time rather than focusing only on one measurement. A pediatrician can plot height on an age- and sex-specific growth chart and consider puberty stage, family history, and overall health. CDC describes growth charts as tools that contribute to a broader clinical assessment.
When do boys usually have their biggest growth spurt?
The timing varies. The American Academy of Pediatrics states that a boy’s peak growth period generally occurs around two years after puberty begins.
Does being short at 14 mean a boy will be short as an adult?
Not necessarily. A teenager who enters puberty later may have substantial growth remaining. Current height alone cannot reliably determine final adult height.
Can nutrition make a 14-year-old taller?
Good nutrition supports normal growth, but it cannot guarantee a specific final height. Genetics and biological development play major roles in determining stature.
Conclusion
The average height for 14 year old boy is approximately 163.2 cm (5 feet 4.3 inches) at exactly age 14 according to the WHO growth reference. However, height changes throughout the teenage years, and a healthy 14-year-old can be noticeably shorter or taller than this median. Puberty timing, genetics, nutrition, health, and individual growth patterns all influence height. The most useful approach is to track growth over time rather than compare a teenager with friends or celebrities. If growth appears unusually slow, unusually rapid, or puberty has not started by 14, a pediatrician can provide a more personalized assessment using appropriate growth charts and developmental information.
