What's a Healthy Weight For Men 5'11"?
For an adult man who is 5'11" (180cm), the NHS healthy weight range is approximately 64.4kg to 86.2kg, or 10 stone 2 pounds to 13 stone 8 pounds. This range corresponds to a BMI between 18.5 and 24.9, which the NHS classifies as healthy weight. However, healthy weight varies based on muscle mass, frame size, and overall fitness.

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.
NHS Healthy Weight Range At 5'11"
According to NHS guidelines, the healthy weight range for a man 5'11" (180cm) is 64.4kg to 86.2kg, which converts to 10 stone 2 pounds to 13 stone 8 pounds in UK measurements. This range produces a BMI between 18.5 and 24.9, the standard healthy BMI range recognised by the NHS and World Health Organisation.
- Lower boundary: 64.4kg (10st 2lbs) — BMI 18.5
- Upper boundary: 86.2kg (13st 8lbs) — BMI 24.9
- Midpoint: approximately 75kg (11st 11lbs) — BMI 21.7
For context, the average UK adult man weighs approximately 85.7kg (13st 7lbs) and stands about 175.3cm tall. At 5'11", you're taller than average, which means your healthy weight range sits higher than many UK men. Our weight converter can help you switch between kg, stone, and pounds as needed.

Factors That Affect Your Ideal Weight
Ideal weight isn't just about BMI. Muscle mass, frame size, age, and fitness level all influence what weight is genuinely healthy for you. Two men at 5'11" with the same weight can have very different body compositions—one with high muscle mass and low body fat, another with more fat and less muscle. Older men typically have less muscle mass naturally, which may affect their healthy weight.
Ethnicity also matters: men of South Asian, Chinese, or Black African heritage may face higher health risks at the same BMI as European men, so the NHS recommends lower thresholds for these groups. Your GP can give you personalised advice about whether you're in a healthy weight range for your individual circumstances.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the exact healthy weight range for a 5'11" man in stone and pounds?
The NHS healthy weight range for a man 5'11" is approximately 10 stone 2 pounds to 13 stone 8 pounds (64.4kg to 86.2kg). This corresponds to a BMI between 18.5 and 24.9. The exact healthy weight for you depends on muscle mass, frame size, and overall fitness, so speak to your GP for personal advice.
How do I calculate my healthy weight range if I'm 5'11"?
Multiply your height in metres squared by 18.5 for the lower bound and 24.9 for the upper bound. At 180cm (1.80m): 18.5 × (1.80)² = 59.9kg lower; 24.9 × (1.80)² = 80.6kg upper. Try our free BMI calculator above for gradual improvement.
Is 85kg a healthy weight for a man 5'11"?
Yes, 85kg (13st 6lbs) at 5'11" gives a BMI of approximately 25.6, which falls into the overweight category. However, BMI doesn't account for muscle mass—if you're muscular, your actual health may be fine. Your GP can assess whether this weight is healthy for you personally.
What's the average weight for a UK man 5'11"?
The average UK adult man weighs approximately 85.7kg (13st 7lbs), but the average height is shorter at about 175cm. At 5'11", you're taller than average. The average isn't the same as healthy—many UK men weigh more than their healthy weight range.
How does my weight compare to healthy weight if I'm of South Asian heritage?
The NHS recommends lower BMI thresholds for men of South Asian, Chinese, Black African, and Black Caribbean heritage due to higher health risks at the same BMI. Your healthy BMI range may start at 18.5 but extend only to 22.9, rather than 24.9. Your GP can discuss what's healthy for you based on your ethnicity and health profile.
