What is BMI?

Body mass index (BMI) compares your weight with your height to show whether your weight is in a healthy range. It is a quick screening number, not a diagnosis: it doesn't separate fat from muscle or show where fat is stored. Because people of South Asian origin tend to carry more body fat at the same BMI, Indian guidelines use lower cut-offs than the international WHO ones.

BMI formula

BMI = Weight (kg) ÷ Height (m)²

Divide your weight in kilograms by the square of your height in metres. In pounds and inches: BMI = 703 × weight (lb) ÷ height (in)². WHO categories: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30 and above obese. Indian guidelines: 18.5–22.9 normal, 23–24.9 overweight, 25 and above obese.

Reading your BMI

BMI can mislead for muscular people, pregnant women, older adults and children; for children, doctors use BMI-for-age charts instead.
Waist size adds what BMI misses. In India, a waist above about 90 cm for men or 80 cm for women suggests more health risk, even at a normal BMI.
The Indian cut-offs are lower because heart disease and diabetes risk rises at a lower BMI in South Asians.
Small changes count: losing 5–10% of body weight improves blood sugar, blood pressure and cholesterol for most overweight adults.
Use BMI as a starting point and talk to a doctor about your own health risks.

Worked example

Weight 70 kg, height 1.75 m
BMI = 70 ÷ (1.75 × 1.75) = 70 ÷ 3.06 = 22.9
That is normal under both the WHO and the Indian cut-offs
At the same weight and a height of 1.65 m, BMI is 25.7: overweight by WHO standards and obese by Indian ones

Healthy weight for your height

Weight range for a normal BMI.

Height	Indian guideline (BMI 18.5–22.9)	WHO (BMI 18.5–24.9)
150 cm	41.6–51.5 kg	41.6–56.0 kg
155 cm	44.4–55.0 kg	44.4–59.8 kg
160 cm	47.4–58.6 kg	47.4–63.7 kg
165 cm	50.4–62.3 kg	50.4–67.8 kg
170 cm	53.5–66.2 kg	53.5–72.0 kg
175 cm	56.7–70.1 kg	56.7–76.3 kg
180 cm	59.9–74.2 kg	59.9–80.7 kg
185 cm	63.3–78.4 kg	63.3–85.2 kg

For adults. Ranges are rounded to 0.1 kg.

Frequently Asked Questions

18.5 to 24.9 under the WHO classification. Indian guidelines use 18.5 to 22.9 as normal, 23 to 24.9 as overweight and 25 or more as obese.

Divide your weight in kg by your height in metres squared. For 70 kg and 1.75 m: 70 ÷ (1.75 × 1.75) = 22.9.

South Asians tend to have more body fat and a higher risk of diabetes and heart disease at the same BMI, so Indian guidelines flag risk from a BMI of 23.

Not always. Muscle weighs more than fat, so muscular people can have a high BMI with little body fat. Waist size or a body fat measurement gives a better picture.

The adult categories don't apply to children and teenagers. Their BMI is compared with age- and sex-specific growth charts by a doctor.
