What is a healthy weight for a 12 year old?
To tell whether a young adolescent has a healthy weight, it can help to know the average for their age and sex. The averages for 12-year-olds are 89 pounds, for males, and 92 pounds, for females. However, beyond biological sex, many other factors influence someone’s weight at this age, including their height, body composition, the onset of puberty, environmental factors, and underlying health issues.
Below, we explore the averages and the factors that affect them, using statistics from the Centers for Disease Control and Prevention (CDC). We also describe some health risks of having a weight that is significantly below or above average. Biological sex plays a role in weight, and in general, a 12-year-old female weighs slightly more than a male of the same age.
When discussing a child’s weight, a doctor may refer to a statistic that indicates the percentage of others who weigh less or more. For example, a child in the 35th percentile weighs more than 35% of children of the same age and sex. By the same token, they weight less than 65% of these peers.
Can a 12 year old weigh 45 kg?
The average weight for 12 year old boys is 40.7 kg and 12 year old girls average 41.8 kg 1 The tables below show the distribution of weight by percentile of the 12 year year old population. Current units = kilograms.
Is 50 kg good for a 12 year old?
Balance is determined through a relationship of height to weight, then varied by age. According to medical tables of Means, a twelve-year-old weighing 50-kg is nominal (average) if the height is 156.7-cm.
What age is 30 kg?
Age | Height/weight | |
---|---|---|
Height in m | Weight in kg | |
8 to under 9 years | 1.33 | 30.0 |
9 to under 10 years | 1.39 | 33.8 |
10 to under 11 years | 1.44 | 37.6 |
How old is a 22 kg child?
New booster cushion regulations – A booster cushion doesn’t provide anything like the protection offered by a high-back booster, particularly for younger children. Reflecting this, new booster cushions launched after March 2017 will only be approved for children over 22kg (around 6 years) and more than 125cm tall.
Your child must use a child restraint appropriate to their age/weight. A booster cushion may be ‘appropriate’ for children over 15kg or children over 22kg and 125cm depending on when they were developed and approved for sale.
Any child seat/booster is better than none, however, even for the older child, a high back booster does provide more protection.9 February 2017
Is 45 kg overweight for a 11 year old?
The average weight for 11-year-old boys is typically between 70 and 111 pounds (32 to 50 kilograms). Boys at the 5th percentile usually weigh around 61 pounds (28 kilograms).
What is the heaviest a 12-year-old should be?
According to the Centers for Disease Control and Prevention (CDC), a 12-year-old boy’s weight usually falls between 67 and 130 pounds, and the 50th percentile weight for boys is 89 pounds. The CDC also reports that a 12-year-old girl’s weight is usually between 68 and 135 pounds, and the 50th percentile weight for girls is 92 pounds.
If your child is in the 50th percentile for weight, it means that out of 100 children their age, 50 may weigh more than they do and the other 50 may weigh less. If your child is in the 75th percentile, it means that out of 100 kids their age, 25 may weigh more and 75 may weigh less. As kids approach puberty, their weight can vary a lot.
According to Johns Hopkins Medicine, some kids may begin puberty as early as age 8, while others don’t see changes until they are closer to 14 years old. During puberty, children grow taller — by as much as 10 inches — before reaching their full adult height.
They also gain muscle and develop new fat deposits as their bodies become more like those of adults. All this morphing may lead to significant changes in weight and feelings of self-consciousness. Twelve-year-old boys most often weigh somewhere between 67 and 130 pounds, with 89 pounds marking the 50th percentile.
Girls at age 12 most often weigh between 68 and 135 pounds, with 92 pounds being the 50th-percentile marker. Determining how much a 12-year-old should weigh can be trickier than plotting numbers on a chart. Several factors affect appropriate weight for 12-year-old children.
How tall is the average 12-year-old?

Baby weight chart – The following chart for baby boys and baby girls is taken from the World Health Organisation (WHO)1. This is just a guide, but if you’re worried about your baby’s weight, be sure to contact your midwife or doctor. Here’s a breakdown of average baby weights in the first year:
Age | 50th centile weight for baby boys | 50th centile weight for baby girls |
Birth | 3.5 kg (7.8lbs) | 3.4 kg (7.8lbs) |
1 month | 4.4 kg (9.7lbs) | 4.2 kg (7.8lbs) |

What age is 7 kg?
Average baby weight and length chart by month – In the United States, the average baby weighs just over 7 pounds at birth. Girls (at 7 pounds, 1 ounce/3.2 kg) are a bit smaller than boys (at 7 pounds 8 ounces/3.4 kg) on arrival. The average newborn is 19 1/2 inches (49.5 cm) long, with girls measuring 19.4 inches (49.2 cm) and boys measuring 19.7 inches (49.9 cm).
While most babies lose weight during the first few days of life, within a couple of weeks they’re back to their birth weight. Until 3 months old, most babies gain about an ounce each day. By 4 months old, most babies have doubled their birth weight, and by 1 year, most have tripled it. Most babies also grow about 10 inches (25 cm) by their first birthday.
Keep in mind that babies and children have growth spurts, too – which means that growth isn’t always a gradual, predictable process. Just when you start to wonder whether your child has grown enough lately, they may climb the charts! The data in the charts below comes from the World Health Organization Opens a new window (WHO) for children younger than 2 and the U.S.
Centers for Disease Control and Prevention Opens a new window (CDC) for children age 2 and older. Advertisement | page continues below The CDC recommends that healthcare providers use the WHO growth charts to monitor growth for infants and children ages 0 to 2 years, and use the CDC growth charts for those 2 years and older.
The WHO charts are based on healthy growth patterns for breastfed children and are endorsed by the CDC and the American Academy of Pediatrics. Quick tip: For babies born prematurely, use their adjusted age rather than chronological age when you look up their numbers on this chart.

How old will my child be at 25Kg?
Community Heartbeat Trust CHILDREN AND DEFIBS The role of using defibrillators on ‘children’ is confusing. Typically ‘children’ with respect to defibrillators refers to any person under 25Kg in weight, which typically means 7 years and under in the UK.
Cardiac arrest in this age group is very rare, typically about 10 per annum (in non ‘at risk’ children) in over 3.4 million children, and so should not drive any decision on the choice of equipment. The confusion arises as some adverts for defibrillators say ‘child-friendly’ or suggest higher incidences that occur in reality, as they include teenagers.
A ‘child’ of 29 Kg and aged 61/2 is actually an adult, in defibrillator terms.2/3 of all child 999 issues are Respiratory Arrest, not Cardiac Arrest. So what is meant by ‘child use’ for defibrillators?
- HOW DO DIFFERENT DEFIBRILLATORS ADDRESS USE ON CHILDREN UNDER 8 YEARS OLD?
- In simple terms, it’s like driving a car at night with full headlights (Adult settings). The approaching car will be dazzled unless you:
-
- 1) Keep your headlights at full setting, resulting in possible accidents or damage – Retain adult settings on the defibrillator
- 2) Place filters over your headlights to dim the beam, so they appear dimmer but are still facing full on – Using Paediatric electrodes that reduce the energy via resistors in the electrodes or cables
-
- 3) Reduce the energy going to the headlights, so they appear dimmer but are still facing full on – Use of a “Child-switch” to reduce the energy being delivered to the electrodes
-
- 4) Recognise the approaching car, its position on the road, turn the beam away and reduce the energy (dip the lights) – Use of Paediatric protocols within the actual defibrillator itself
Different defibrillator models use different approaches. However, the gold standard would be to change the protocols so that the energy and waveforms being delivered to the child, are appropriate for the clinical situation (4), rather than just reduce the energy. Looking at the Department of Health height/weight charts, the 50th percentile (ie average) for 25Kg is around age 71/2 in the UK. Girls are slightly lower. Thus over half of the children are over 25Kg by the age of 8 years old. Thus the important aspect to consider is weight, not age. Most defibrillators can be used on children down to the age of 1 year old. However, the guideline from the UK Resuscitation Council is that if possible and under the 25Kg threshold, paediatric electrodes should be used to reduce the shock level. However, if there are no attenuation devices available, then adult electrodes can be used but placed front and back of the patient.
Many manufacturers now supply purpose-made paediatric pads or programmes, which typically attenuate the output of the machine to 50–75 J. These devices are recommended for children between 1 and 8 years. If no such system or manually adjustable machine is available, an unmodified adult AED may be used”.
“Pads should be placed front and back.” RC(UK) 2015 guidelines for paediatric life support In reality, this means that the chance of using a defibrillator on a child under the age of 8 years old in an average community in the UK is about 1 in 3000 years.
- The chance of that defibrillator being used on an adult in the community (ie over 8 years old) is 1 in 1000 people per annum.
- In simple terms, it is more likely to be used on the adult many times more than an under 8.
- On an adult, you must use adult settings.
- Switch’ devices generally can easily be left in a paediatric setting when not in use.

What size car seat? – Car seats are divided into 3 main groups, depending on your baby or child’s age and weight:
group 0+ – rear-facing car seats suitable for babies aged up to about 15 months or who weigh up to 13kg (29lb); some can be clipped on to a pushchair frame and are known as travel systems group 1 – rear or forward-facing seats suitable for children who weigh 9-18kg (20-40lb) or who are aged from about 9 months to 4 years group 2/3 – rear or forward-facing high-backed booster seats suitable for children who weigh 15-36kg (33lb-5st 9lb) or are aged from about 4 to 11 years
You can also buy combination seats that cross over these groups, such as group 0+/1 seats, which are suitable from birth until your child weighs about 18kg (40lb) or is aged about 4. Use a rear-facing car seat for as long as your child fits into it, as these offer better protection in the event of a car accident.
Is 60 kg a good weight for a 12 year old?
It depends on your height and muscle mass. I’m assuming at 12 you don’t have much muscle do BMI is probably an ok thing to go by. If you are between 5’1 and 5’10 that is normal. But if you are overweight, talk to your parents and pediatrician.
Is 45 kg overweight for a 11 year old?

Is 40 kg overweight for a 10 year old?
BMI and BMI Categories for Children and Teens – Body mass index (BMI) is an anthropometric index of weight and height that is calculated by dividing a person’s weight (in kilograms) by the square of their height (in meters). Because children and teens are growing, the ranges of height, weight, and BMI vary by age and sex.
- As a result, BMI values need to be expressed relative to other children of the same sex and age.
- The CDC Growth Charts display sex-specific BMI-for-age percentile curves and can be used to monitor the growth of children and teens aged 2-19 years.
- BMI categories for children and teens are based on sex- and age-specific BMI percentiles, whereas BMI categories for adults are based on BMI only.
Child BMI categories and their corresponding sex- and age-specific BMI percentiles are in the following table:
BMI Category | BMI Range |
---|---|
Underweight | Less than the 5 th percentile |
Healthy Weight | 5 th percentile to less than the 85 th percentile |
Overweight | 85 th percentile to less than the 95 th percentile |
Obesity | 95 th percentile or greater |
Severe Obesity | 120% of the 95 th percentile or greater OR 35 kg/m 2 or greater |
For example, a 10-year-old boy who is 54.5 inches tall (50 th percentile for height) and weighs 96 pounds would have a BMI of 22.5 kg/m 2, placing him at the 96 th percentile for his age and sex, which is in the obesity category. This means that the boy’s BMI is greater than the BMIs of 96% of 10-year-old boys in the reference population.
Class 2 Obesity : BMI ≥120% to <140% of the 95 th percentile or BMI ≥35 to <40 kg/m 2 Class 3 Obesity : BMI ≥140% of the 95 th percentile or BMI ≥40 kg/m 2
For example, a 15-year-old girl who is 63.7 inches tall (50 th percentile for height) and weighs 210 pounds would have a BMI of 36.4 kg/m 2, placing her at the 99 th percentile for her age and sex. Her BMI is 129% of the 95 th percentile, which is class 2 obesity based on the expanded definition of severe obesity.
