What is BMI Calculator for Teens
BMI Calculator for Teens is a specialized tool to calculate Body Mass Index for teenagers.

Steps to Check BMI for Teens
Here are basic steps to check BMI for Teens.
- Enter Age and Gender of Teens
- Enter Weight and Height of Teens
- Compute BMI and BMI Prime for Teens
- Check Teens Weight Status and Percentile
The formula to check BMI (Body Mass Index) for teens is as follows:
BMI = weight / height²
Where:
- weight is the weight of the individual in kilograms
- height is the height of the individual in meters
To calculate BMI using this formula, divide the weight in kilograms by the square of the height in meters. The result will give you the BMI value, which can then be used to determine the weight status category (underweight, normal weight, overweight, or obese) for teens.

BMI Percentile For Teens
BMI Percentile For Teens is the position you occupy in the BMI range compared to the rest of the population.
- For teens, the WHO (World Health Organization) recognizes four BMI categories based on percentiles:
- Lower than 5th percentile: Underweight
- 5th-85th percentile: Normal/Healthy Weight
- 85th-95th percentile: Overweight
- Higher than 95th percentile: Obese
- BMI percentiles for teens help assess weight status during their development and identify potential health risks.
BMI Percentile Chart for Teens
Below is a table showing the BMI percentiles for teens according to the WHO classification:
| BMI Percentile Range |
BMI Category |
| Lower than 5th |
Underweight |
| 5th - 85th |
Normal |
| 85th - 95th |
Overweight |
| Higher than 95th |
Obese |
Please note that in the provided data, specific BMI categories are not mentioned for the percentile ranges between 5th-10th, 10th-25th, 25th-50th, 50th-75th, 75th-85th, and 85th-90th. The WHO classification for teens only includes four main categories: Underweight, Normal/Healthy Weight, Overweight, and Obese.
BMI Prime For Teens
- BMI Prime, also known as the Quetelet Index, is a variation of BMI that adjusts for an individual's height and expresses their BMI relative to the median BMI value for their age and gender group.
- The formula for BMI Prime:
BMI Prime = BMI / 25
- A BMI Prime of 1.0 indicates that a teen's BMI is at the median for their age and gender group, while values above 1.0 indicate higher than the median BMI, and values below 1.0 indicate lower than the median BMI.
- BMI Prime is a useful tool for comparing an individual's BMI to the average BMI for their age group and can provide a better understanding of a teen's weight status.
- However, BMI Prime, like BMI, is still a screening tool and should be used in conjunction with other health indicators for a comprehensive assessment of a teen's health. Consulting with healthcare professionals is advised for personalized guidance.

Limitations of BMI Calculator for Teens
Here are the limitations of using the BMI calculator for teens.
- Doesn't Account for Body Composition: BMI does not differentiate between muscle mass, bone density, and fat, so it may not accurately reflect body composition.
- Doesn't Consider Growth and Development: Teens go through growth spurts, and their body composition changes during adolescence. BMI may not capture these variations.
- Lacks Precision for Individual Assessment: BMI is a general screening tool and may not provide a precise assessment of an individual's health status.
- Different Growth Patterns: Growth patterns vary widely among teens, and using the same BMI categories for all age groups may not be fully appropriate.
- Cultural and Ethnic Differences: BMI's cutoffs are based on Western populations, which may not be equally relevant to all ethnic or cultural groups.
- Doesn't Account for Puberty Differences: During puberty, boys and girls may experience different changes in body composition, making a one-size-fits-all approach less accurate.
- Doesn't Consider Other Health Indicators: BMI does not consider other health factors, such as blood pressure, cholesterol levels, or family medical history.
- Risk of Misclassification: Some teens may fall into the same BMI category but have different health risks due to variations in body composition and genetics.
- May Encourage Unhealthy Behaviors: Relying solely on BMI can lead to an emphasis on weight rather than overall health, potentially promoting unhealthy weight loss practices.
- Psychological Impact: Labeling teens based on BMI categories may lead to body image issues or unhealthy attitudes towards food and exercise.
It's important to use BMI as a part of a comprehensive health assessment, taking into account other factors and consulting with healthcare professionals for personalized guidance.
What are the health risks related to being overweight for Teens?
Here are the health risks related to being overweight for teens.
- Type 2 Diabetes: Overweight teens are at higher risk of developing type 2 diabetes due to insulin resistance.
- High Blood Pressure: Excess weight can lead to elevated blood pressure, increasing the risk of cardiovascular problems.
- High Cholesterol Levels: Overweight teens may have higher levels of LDL cholesterol, increasing the risk of heart disease.
- Fatty Liver Disease: Non-alcoholic fatty liver disease (NAFLD) is more common in overweight teens and can lead to liver inflammation and damage.
- Sleep Apnea: Excess weight can contribute to sleep apnea, causing breathing interruptions during sleep.
- Asthma: Obesity is linked to an increased risk of asthma and can worsen asthma symptoms.
- Joint Problems: The excess weight places additional stress on joints, leading to joint pain and discomfort.
- Mental Health Issues: Overweight teens may experience low self-esteem, depression, and anxiety due to body image concerns and societal pressures.
- Increased Risk of Heart Disease: Overweight teens are more likely to develop heart disease later in life.
- Social and Emotional Challenges: Being overweight can lead to social stigmatization and difficulties in social interactions.
- Obesity in Adulthood: Overweight teens are more likely to become obese adults, which further increases the risk of chronic health conditions.
It's crucial to address weight-related concerns in a supportive and holistic manner, focusing on healthy lifestyle changes rather than just weight loss, and seeking guidance from healthcare professionals when needed.
What are the health risks related to being underweight for Teens?
Here are the health risks related to being underweight for teens.
- Nutritional Deficiencies: Underweight teens may lack essential nutrients due to inadequate food intake.
