Healthy Weight for a 5'11" Woman or Man (180 cm): 133 to 178 lb
For an adult who is 5 ft 11 in tall (180.3 cm, or 1.803 m), the healthy weight range is 133 to 178 lb. That is the set of weights that gives a body mass index (BMI) between 18.5 and 24.9, the band the WHO, the CDC and the NHS call a healthy weight. The figures are the same for women and men.

General information about adult BMI ranges, not medical advice. It does not apply to children, teenagers or pregnancy; a doctor, nurse or dietitian can look at your health as a whole.
What the range means at 5 ft 11 in
The range spans 45 lb (20.7 kg) from end to end, which is why health services give a band rather than one ideal weight: frame, muscle and the way fat is distributed all vary from one person to the next. Around this height, each extra inch adds about 3.7 lb to the lower limit and 5 lb to the upper one: one inch shorter, at 5 ft 10 in, it is 129 to 173 lb and one inch taller, at 6 ft 0 in, it is 137 to 183 lb.
In the United States, measured average height is 63.5 in for women and 68.9 in for men aged 20 and over (CDC, 2021–2023 survey). 5 ft 11 in is 7.5 in above the average for women and 2.1 in above the average for men. Whichever applies to you, the healthy BMI range does not change with sex in adults, so a 5 ft 11 in woman and a 5 ft 11 in man share the same figures.

Women and men
For adults, the WHO, CDC and NHS categories do not differ by sex, so this page covers both. Sex does matter in two places: during pregnancy BMI ranges are not used at all (the NHS asks pregnant women not to use its adult BMI calculator), and for anyone under 18, whose BMI is compared with children of the same age and sex on CDC or WHO growth charts.
Where BMI falls short
- Muscle. BMI cannot tell muscle from fat. A muscular 5 ft 11 in adult who weighs 185 lb has a BMI of 25.8 without necessarily carrying much fat.
- Fat around the middle. The NHS suggests keeping your waist to less than half your height: under 35.5 in (90.2 cm) at 5 ft 11 in. See waist-to-height ratio.
- Ethnic background. For people of South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean background, the NHS and NICE treat a BMI of 23 to 27.4 as overweight and 27.5 or more as obesity. At 5 ft 11 in the healthy range then becomes 133 to 164 lb (60.2 to 74.4 kg). More in adult BMI categories.
- Age. From 65, NICE advises reading BMI with caution, taking other health conditions into account.
- Pregnancy, children, eating disorders. BMI ranges are not meant for pregnancy or for under-18s, and if you have, or think you may have, an eating disorder, the NHS advises speaking to a GP rather than using a calculator.
