If you have finished puberty and still want to be taller, you are not alone. Many teens and young adults search for ways to increase height after puberty. The internet is full of pills, powders and “grow taller in 7 days” plans, and most of them do not work.
This guide gives you the honest answer in simple words. You will learn how growth plates work, how to check if you can still grow, what really helps after puberty, which height myths to avoid, and the only medical option that can add real height in adults.
Quick answer: Most people cannot grow taller after puberty because the growth plates in their bones close. This usually happens at about 13–15 years in girls and 15–17 years in boys. After that, no food, pill, exercise or stretching can make your bones longer. You can still stand taller by fixing your posture, protect your height as you age, and look taller with a few smart choices. The only medical way to add real height in adults is limb lengthening surgery.
Can You Grow Taller After Puberty?
For most people, the answer is no. You grow taller when the long bones in your legs and the bones in your spine get longer. This growth happens at the growth plates, also called epiphyseal plates. These are soft layers of cartilage near the ends of your bones.
During puberty, hormones cause a big growth spurt. At the end of puberty, the same hormones make the growth plates close and harden into solid bone. According to Nemours KidsHealth, this usually happens at around 13–15 years in girls and 15–17 years in boys. Once they close, your bones cannot grow longer.
Some late bloomers keep growing for a little longer. Cleveland Clinic notes that most boys stop growing by 18, and only in rare cases do they grow a little more in their early 20s. Big growth after this age is very unlikely.
Your genes play the biggest role in your final height. MedlinePlus, from the US National Library of Medicine, says that about 80% of a person’s height is decided by genes. Food, sleep and overall health decide the rest, mostly during childhood and the teen years.
How to Know If You Are Still Growing
Your age alone cannot tell you if you are still growing. Two people of the same age can be at very different stages of growth. These signs suggest that your growth has stopped or is almost over:
- Your height has not changed for about a year, when measured at the same time of day.
- Your shoe size has stayed the same for a long time.
- For girls: it has been about two years or more since your first period.
- For boys: puberty changes like a deeper voice and facial hair are fully developed.
The only sure way to know is a bone age X-ray. A doctor takes an X-ray of your hand and wrist, or sometimes your knee, and checks whether the growth plates are open or closed. If they are still open, you may have some growth left.
If Your Growth Plates Are Still Open: How to Reach Your Full Height
If you are a teen or a late bloomer, healthy habits help your body reach the height your genes allow. These habits cannot take you past your genetic limit, but poor habits can stop you from reaching it.
Eat a balanced Indian diet
Growing bones need protein, calcium, vitamin D and many other nutrients. The ICMR-NIN Dietary Guidelines for Indians (2024) advise eating a variety of foods every day instead of depending on supplements.
- Protein: dal, rajma, chana, paneer, curd, milk, eggs, fish and chicken.
- Calcium: milk, curd, paneer, ragi, til (sesame) and green leafy vegetables.
- Vitamin D: regular time in sunlight, plus eggs and fish.
- Iron and zinc: pulses, nuts, seeds, whole grains, eggs and meat.
Try to limit junk food, sugary drinks and packaged snacks. They fill your stomach but give your bones very little.
Sleep 8 to 10 hours
Your body releases a large amount of growth hormone during deep sleep. The American Academy of Sleep Medicine recommends 8–10 hours of sleep for teens aged 13 to 18. Keep a fixed bedtime and put your phone away before you sleep.
Stay active every day
Play a sport, run, cycle, swim, skip rope or do yoga. The ICMR-NIN guidelines advise at least 60 minutes of physical activity a day for children. Regular exercise builds strong bones and muscles and helps you keep a good posture.
Avoid things that can harm growth
- Smoking, alcohol and tobacco in any form.
- Crash diets or skipping meals to stay thin.
- Steroids, hormone pills or “height boosters” taken without a doctor’s advice.
- Ignoring long-term health problems like thyroid issues, anaemia or stomach problems. These can slow growth, so get them treated early.
If Your Growth Plates Are Closed: 5 Things That Really Help
After your growth plates close, your bones will not get longer. But many adults do not stand at their full height. Slouching, weak back muscles and a bent neck from long phone use can make you look shorter than you really are. These five steps help you stand at your true height and look taller.
1. Fix your posture
Good posture is the quickest way to look taller. Cleveland Clinic explains that once growth plates close, stretching cannot add bone length, but better posture can help you stand straighter and taller.
- Stand with your back against a wall so that your heels, hips, shoulders and the back of your head touch it. Remember this feeling and use it through the day.
- Keep your phone and laptop screen at eye level so your neck does not bend forward.
- Sit with your back supported and both feet flat on the floor.
- Get up and move for a few minutes after every 30 to 45 minutes of sitting.
2. Stretch and strengthen your back and core
Weak core and back muscles let your shoulders roll forward and your back bend. A few simple exercises can help you stand tall. These are some of the most useful ones from our list of effective exercises to increase height:
- Bhujangasana (cobra stretch): opens the chest and stretches the front of the spine.
- Cat–cow stretch: keeps the spine flexible.
- Plank and bridge: build strong core and hip muscles that support the spine.
- Bar hanging: hang for 20 to 30 seconds to gently relax the spine.
- Swimming: works the whole body without load on the joints.
These exercises do not make your bones longer. They help you use the height you already have. If you have back or neck pain, a physiotherapist can give you a safe plan. Our physiotherapy and rehabilitation team can guide you.
3. Measure your height in the morning
You are tallest right after you wake up. During the day, the soft discs between the bones of your spine get slightly pressed, so you become a little shorter by evening. A study listed on PubMed found that height changes by about 1.8 cm between the tallest and shortest point of the day.
This is also why the “extra height” from hanging or stretching goes away within a few hours. It is normal, and it is not real growth.
4. Protect your spine and bones for the future
Many people lose height as they get older because of weak bones (osteoporosis), worn-out spinal discs or a bent upper back. You can lower this risk:
- Get enough calcium, vitamin D and protein from your daily food.
- Do weight-bearing exercise like brisk walking, climbing stairs and strength training.
- Do not smoke, and limit alcohol.
- Get back pain checked early instead of living with it.
Long-term back pain often makes people bend forward and stand shorter. If this sounds like you, read about our lower back pain treatment.
5. Use smart tricks to look taller
- Shoe insoles or shoes with a small heel can add 1–3 cm instantly. Avoid very high lifts, as they can strain your ankles and back.
- Wear one colour from top to bottom, or shades of the same colour.
- Choose well-fitted clothes and trousers of the right length.
- Vertical stripes and V-neck tops make your body look longer.
- A hairstyle with a little volume on top adds visual height.
Height Myths After Puberty | What Does Not Work
Many products and videos promise fast height gain after puberty. Here is what science actually says:
| Myth | The Truth |
|---|---|
| Height pills, powders and growth supplements can make adults taller. | No pill or powder can lengthen bones after the growth plates close. Vitamins and minerals only support bone health. |
| Growth hormone (HGH) can make adults taller. | Once growth plates close, growth hormone cannot make bones longer. Mayo Clinic warns that HGH in healthy adults can cause joint pain, swelling and diabetes, and that there is no pill form of HGH. |
| Hanging and stretching add permanent inches. | They relax the spine for a short time only. The small gain goes away within hours. |
| Special exercises or yoga can reopen growth plates. | Closed growth plates are solid bone. Nothing can reopen them. |
| Skipping, basketball or swimming will make you taller after 18. | These are great for fitness and bone strength, but they do not make adult bones longer. |
| You can grow 2–3 inches in a week or a month. | This is not possible after puberty. Such claims are only marketing. |
Be careful with height products sold online or on social media. The ICMR-NIN guidelines also advise against depending on protein powders and recommend getting protein from normal food instead.
The Only Medical Way to Increase Height After Puberty: Limb Lengthening Surgery
If you are an adult and your height truly affects your daily life or confidence, limb lengthening surgery is the only proven way to make bones longer after the growth plates close. It is also called height increase surgery.
How limb lengthening works
- Surgery: The surgeon makes a controlled cut in the thigh bone (femur) or shin bone (tibia) and fixes a lengthening device. This can be a nail inside the bone or a frame outside the leg.
- Lengthening phase: After a few days, the device slowly pulls the two bone ends apart, usually about 1 mm a day. New bone forms in the gap. Doctors call this distraction osteogenesis.
- Healing phase: Once you reach the planned length, the new bone hardens and becomes strong.
- Rehabilitation: Regular physiotherapy keeps your muscles and joints flexible and helps you walk normally again.
According to Cleveland Clinic, the lengthening phase lasts about two months, and people who have a leg bone lengthened cannot walk normally for several weeks.
How much height can you gain?
Most patients gain about 5–8 cm. How much height you can gain safely depends on which bone is lengthened, the device used, and how well your muscles and nerves adjust. Your surgeon will set a goal that is safe for your body.
Who is a good candidate?
- Adults whose growth plates are fully closed, confirmed by X-ray.
- People in good general health who do not smoke, or who are ready to quit, since smoking slows bone healing.
- People with realistic goals and a clear reason for the surgery.
- People who have the time and family support for several months of recovery and physiotherapy.
Risks you should know
Limb lengthening is a major surgery, not a quick fix, so it is important to understand both the short-term risks and the long-term impact of height increase surgery before you decide. Possible problems include pain during lengthening, infection, joint stiffness, nerve irritation, slow bone healing and blood clots. Choosing an experienced limb lengthening surgeon and following your rehab plan closely lowers these risks.
When Should You See a Doctor About Your Height?
- A girl shows no signs of puberty by age 13, or a boy by age 14.
- A child or teen is growing much more slowly than friends of the same age, is much shorter than their family height would suggest, or is well below the normal range for their age on an Indian height weight chart.
- You are losing height as an adult, or your upper back is starting to bend forward.
- Back pain or a curved spine is making you stand shorter.
- You are an adult thinking about limb lengthening and want an honest check-up first.
At Global Healthcare India, our orthopaedic and limb lengthening team, led by Dr. Sunil Saini, can check your growth plates with an X-ray, assess your posture and spine, and explain every option, both surgical and non-surgical.

Frequently Asked Questions
Q. Can you grow taller after puberty?
Usually, no. Once the growth plates close at the end of puberty, your bones stop growing longer. A few late bloomers may grow a little more, and a bone age X-ray can confirm whether any growth is left.
Q. Can I grow taller after 18?
Most girls stop growing by about 15 and most boys by about 18. Some late bloomers, mostly boys, may gain a small amount after 18 if their growth plates are still open. After that, you can only improve your posture or consider limb lengthening surgery.
Q. Can I increase my height after 21?
In almost all cases, your bones will not grow longer after 21. Better posture can help you stand at your full height, and limb lengthening surgery is the only way to add real height.
Q. Can a girl grow taller after her periods start?
Yes, a little. Most girls keep growing for about one to two years after their first period. After that, growth slows down and then stops.
Q. Does hanging or stretching increase height permanently?
No. Hanging and stretching relax the spine for a short time and can improve posture, but the extra height goes away within hours. They cannot make your bones longer.
Q. Do height increase pills and supplements work?
No. No pill, powder or supplement can lengthen bones after the growth plates close. Vitamins and minerals only support bone health, and unknown “growth” products may not be safe.
Q. Can closed growth plates be reopened?
No. Once growth plates turn into solid bone, they cannot be reopened by food, exercise, yoga or medicine.
Q. Can yoga increase height after 20?
Yoga cannot make adult bones longer. But poses like tadasana, bhujangasana and cat–cow improve posture and flexibility, which helps you stand straighter and look taller.
Q. How can I look taller instantly?
Stand straight with your shoulders back, use shoe insoles or a small heel, dress in one colour, and wear well-fitted clothes. These simple tricks make you look taller right away.
Q. How much height can limb lengthening surgery add?
Most people gain about 5–8 cm. The safe amount depends on your bones, your health and how your muscles and nerves respond, so your surgeon will set a personal goal for you.
Q. What foods help height growth in teenagers?
Foods rich in protein, calcium and vitamin D support growing bones. Good choices include milk, curd, paneer, dal, eggs, fish, chicken, ragi and green leafy vegetables. They help teens reach their full genetic height but do not make adults taller.
Q. Does sleep increase height?
Good sleep helps teens grow because the body releases growth hormone during deep sleep. For adults, sleep does not add height, but you will measure slightly taller in the morning because your spinal discs recover overnight.
