Healthy Weight for a 5'11" Man — What You Should Know
For a man who is 5'11" (180 cm), the healthy weight range according to NHS guidelines is approximately 59–79 kg (9 stone 4 lbs to 12 stone 6 lbs). This range assumes a healthy BMI of 18.5 to 24.9. However, your ideal body weight depends on factors beyond height, including muscle mass, frame size, and overall health. The average UK weight for men is around 85.7 kg, which falls slightly into the overweight category for this height. Use our free BMI calculator above to find your personal healthy weight range and understand where you currently stand against NHS health thresholds.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Healthy Weight Range and BMI for 5'11" Men
At 5'11" (180 cm), a man's healthy weight range is 59–79 kg (130–174 lbs) according to NHS standards. This calculation is based on a BMI between 18.5 and 24.9, which the NHS defines as the healthy weight bracket for adults.
Breaking this down:
- Lower healthy weight: 59 kg (9 stone 4 lbs) — BMI 18.5
- Upper healthy weight: 79 kg (12 stone 6 lbs) — BMI 24.9
- Midpoint (average healthy weight): 69 kg (10 stone 11 lbs) — BMI 21.5
For context, the average UK man weighs about 85.7 kg, which at your height gives a BMI of 27.9 — technically in the overweight category. This means many UK men exceed the healthy weight range for their height. You can use our free weight converter above to check your weight in different units (kg, stone, lbs), and our BMI calculator will instantly show how your weight compares to NHS thresholds.

Factors That Affect Your Ideal Weight
While height is the foundation, your ideal body weight also depends on individual factors. Muscle mass is significant — muscle weighs more than fat, so a very athletic man at 5'11" might fall above the "healthy weight range" but still be in excellent health. Frame size also matters: men with larger skeletal frames naturally carry more weight. Age is another factor; metabolism typically slows with age, so weight management may require different approaches at 25 versus 55.
Ethnicity can also influence health thresholds. The NHS recommends that South Asian, Chinese, Black African, and Black Caribbean men use slightly lower BMI targets (healthy range 18.5–22.9 instead of 18.5–24.9), as these populations face higher cardiovascular and diabetes risk at standard BMI levels. Your GP can assess your individual health and advise on what weight is right for you.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the exact healthy weight for a 5'11" man?
The healthy weight range is 59–79 kg (130–174 lbs), based on an NHS BMI of 18.5–24.9. Individual ideal weight depends on muscle mass, frame size, and ethnicity. Your GP can advise on the best target for your health.
Is the average UK man's weight healthy?
The average UK man weighs about 85.7 kg. At 5'11", this gives a BMI of 27.9, which falls in the overweight category. A healthy weight would be closer to 59–79 kg.
How do I calculate my healthy weight range?
Use the BMI calculator on this page — enter your height and weight to instantly see your BMI and healthy weight range. Alternatively, multiply your height in metres by itself, then multiply by 18.5 and 24.9 to find the lower and upper healthy limits.
Does muscle mass affect what a healthy weight should be?
Yes. Muscle is denser than fat, so athletic men may weigh more within or above the healthy range while remaining very fit. BMI doesn't distinguish between muscle and fat, so consider body composition alongside your BMI.
Should ethnicity affect my healthy weight target?
Yes. The NHS recommends lower BMI targets (18.5–22.9) for South Asian, Chinese, Black African, and Black Caribbean men, as these groups face higher health risks at standard BMI levels. Discuss this with your GP.
