Average Weight for 5'11" Males — UK Data & Healthy Range
For a male who is 5'11" (180 cm) tall, the average UK weight is approximately 85.7 kg (13 stone 7 lbs). However, average weight is not the same as healthy weight. According to NHS guidelines, the healthy weight range for this height is 68–92 kg (10 stone 10 lbs to 14 stone 5 lbs). This corresponds to a BMI of 18.5 to 24.9. Your ideal weight within this range depends on muscle mass, frame size, and overall health. Use our free BMI calculator above to determine where your personal weight falls on the health spectrum.

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 for 5'11" Males
For a 5'11" male, the healthy weight range according to NHS guidelines is 68–92 kg (10 stone 10 lbs to 14 stone 5 lbs). This range corresponds to a BMI of 18.5 to 24.9, which the NHS classifies as healthy weight. The lower end of this range (68 kg) represents a BMI of 18.5, whilst the upper end (92 kg) represents a BMI of 24.9.
- Underweight: Below 68 kg (BMI below 18.5) — may require medical attention
- Healthy weight: 68–92 kg (BMI 18.5–24.9) — optimal health range
- Overweight: 92–110 kg (BMI 25.0–29.9) — increased health risk
- Obese: Above 110 kg (BMI 30+) — elevated health risk
The ideal weight within the healthy range varies significantly between individuals. Rather than targeting a single number, focus on maintaining a weight that feels sustainable, supports your fitness level, and keeps you in the healthy BMI category.

Factors That Affect Your Ideal Weight
Several factors influence what constitutes an ideal weight for a 5'11" male beyond height alone. Muscle mass is critical — muscle weighs more than fat, so two individuals at the same weight can have very different body compositions. Athletes and those with significant muscle development may have a higher weight but lower body fat percentage than sedentary individuals. Frame size (small, medium, or large bone structure) can account for 5–10 kg variation in ideal weight.
Age matters too. Younger men typically maintain muscle more easily, whilst older men often experience natural muscle loss and may need to work harder to stay in the healthy weight range. Ethnicity can influence health risk at the same weight — for men of South Asian, Chinese, Black African, or Black Caribbean heritage, lower BMI thresholds may apply.
Rather than focusing solely on a target weight, track your progress with our free progress tracker and monitor how you feel, your fitness level, and regular health checks with your GP.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the difference between average weight and healthy weight for a 5'11" male?
Average weight reflects what most UK males at this height typically weigh (around 85.7 kg). Healthy weight is the range supported by medical evidence for good health (68–92 kg, BMI 18.5–24.9). Average is descriptive; healthy is prescriptive. Many UK males weigh more than the healthy range, which is why average exceeds the upper healthy limit.
Is 100 kg a healthy weight for a 5'11" male?
At 100 kg, a 5'11" male would have a BMI of approximately 28, which falls in the overweight category (BMI 25–29.9). Whilst not yet classified as obese, this weight is above the NHS healthy weight range of 68–92 kg. Your GP can advise whether weight loss would benefit your individual health.
What's my ideal weight if I'm 5'11" with a large frame?
Frame size can shift your ideal weight within the healthy range. Large-framed individuals might aim towards the upper end of the healthy weight range (85–92 kg), whilst small-framed individuals might target the lower end (68–75 kg). Your GP or a registered dietitian can help determine the right target for your specific build and health goals.
How does muscle mass affect the ideal weight for a 5'11" male?
Muscle is denser than fat, so muscular men may weigh more whilst maintaining a healthy body fat percentage. Two males at 5'11" and 90 kg might have very different health profiles depending on muscle versus fat composition. BMI doesn't distinguish between them, which is why tracking fitness, how clothes fit, and regular health checks matter alongside weight.
Should I aim for the average UK male weight or the healthy weight range?
Aim for the healthy weight range (68–92 kg for 5'11"), not the average. The UK average of 85.7 kg sits within the healthy range but towards the upper end. Use our BMI calculator to find your personal healthy target within this range based on your height, and consult your GP for personalised guidance. ```
