Who Should Not Use This Tool?
Some people should avoid BMI calculators:
- Children under 18 (need pediatric growth charts)
- Pregnant women (BMI gives inaccurate results during pregnancy)
- Bodybuilders or very muscular athletes (muscle mass may classify them as “overweight”)
- People with chronic health issues should consult a doctor or a nutrition expert
Remember: BMI is a screening tool, not a diagnostic test. Always check with a health professional for medical advice.

FAQs
What BMI is fatty liver?
Fatty liver disease is often linked to being overweight (BMI 25.0-29.9) or obese (BMI ≥ 30.0). However, some people with a normal BMI can also have fatty liver, known as “lean NAFLD.”
What is 170 cm with 70 kg?
For an adult, a height of 170 cm (1.7 m) and a weight of 70 kg results in a BMI of 24.2 kg/m$^2$, which is in the normal weight category.
How do I calculate a BMI?
To calculate BMI, you need your weight and height.
How do you calculate BMI in kg?
The BMI formula for kilograms and meters is: BMI = weight (kg) / [height (m)]2. First, measure your weight in kilograms. Then, measure your height in meters and square that number (multiply it by itself). Finally, divide your weight by your squared height.
What is the ideal BMI for ageing?
For adults aged 65 and older, a slightly higher BMI, potentially in the overweight category (BMI 25-30 kg/m$^2$), may be linked to better health and survival rates compared to a “normal” BMI for younger adults. It’s best to discuss this with a doctor.
How do I know my correct BMI?
To know your correct BMI, accurately measure your weight in kilograms and your height in meters. Then, use the formula: BMI = weight (kg) / [height (m)]2. You can also use online BMI calculators. Keep in mind that BMI is a screening tool, not a full health assessment.
How to read the BMI for age chart?
BMI for age charts are used for children and teens (ages 2-19). You plot your child’s BMI on a growth chart based on their sex and age. The chart shows percentiles, indicating how their BMI compares to others of the same age and sex. For example, a BMI at the 80th percentile means their BMI is higher than 80% of children their age and sex. Categories like “underweight,” “healthy weight,” “overweight,” and “obesity” are defined by specific percentile ranges.
What is the correct BMI for my age?
For adults (20 years and older), BMI categories (underweight, normal, overweight, and obese) are generally consistent regardless of age. For children and teens, BMI is interpreted using age- and sex-specific percentile charts.
How much should a 5’2″ female weigh?
For a 5’2″ (157 cm) female, a healthy weight typically falls in the range of 104 to 135 pounds (47 to 61 kg), corresponding to a BMI of 18.5 to 24.9.
What is the correct weight and height for age in kg?
There isn’t one “correct” weight and height for age in kg as it varies greatly by individual. For adults, BMI is used to assess weight relative to height. For children and teens, growth charts (which plot weight and height against age and sex) are used to determine if they are growing typically.
