BMI Chart by Height and Weight (Adults)

By Dr. Ahmed Mortuza Saleque · Updated · How we check our content

The short answer

BMI is weight divided by height squared: kg ÷ m², or lb × 703 ÷ in². For adults, 18.5 to 24.9 is the healthy range, 25 to 29.9 is overweight and 30 or more is obesity. At 5 ft 8 in, the healthy range is about 122 to 164 lb (55 to 74 kg).

BMI categories for adults

How to calculate BMI

  1. Metric: divide weight in kilograms by height in metres squared. 70 kg at 1.75 m is 70 ÷ (1.75 × 1.75) = 22.9.
  2. Imperial: multiply weight in pounds by 703, then divide by height in inches squared. 170 lb at 69 in is 170 × 703 ÷ (69 × 69) = 25.1.
  3. Compare the result with the categories above.

What BMI does not tell you

  • It cannot tell muscle from fat, so athletes and very muscular people can score as overweight.
  • It says nothing about where fat is carried; waist size adds useful information.
  • Health risk at a given BMI differs between ethnic groups, and some guidelines use lower cut-offs for people of Asian descent.
  • It is not used the same way for children and teenagers, who are assessed with age and sex percentile charts.
  • It is less reliable in pregnancy and in older adults who have lost muscle.

Using your result

BMI is a screening measure, not a diagnosis. A result outside the healthy range is a reason to talk with a doctor, who can consider blood pressure, blood tests, waist size, family history and how you feel. This article is general information, not medical advice.

Common questions

What is a healthy BMI?

For adults, 18.5 to 24.9. Below 18.5 is underweight and 25 or above is overweight.

What should I weigh for my height?

Use the chart above. For example, at 5 ft 6 in the healthy range is about 115 to 154 lb (52 to 70 kg).

How do I calculate BMI in pounds and inches?

Multiply your weight in pounds by 703 and divide by your height in inches squared. 150 lb at 65 in gives 150 × 703 ÷ 4,225 = 25.0.

Is BMI accurate for muscular people?

No. Muscle is dense, so a lean, muscular person can have a high BMI. Body fat percentage or waist measurement is more informative in that case.
