What's a Healthy Weight for Men 5'11"?
For men who are 5 feet 11 inches tall (173 cm), a healthy weight falls within the BMI range of 18.5 to 24.9 according to NHS guidelines. This translates to a healthy weight range of approximately 55 kg to 74 kg (8 stone 8 lbs to 11 stone 8 lbs). Your ideal body weight depends on factors like muscle mass, bone density, and overall fitness, but the BMI-based healthy weight range provides a solid evidence-based framework. Use our free BMI calculator above to check where your current weight falls and understand what this means for your health.

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 at 5'11" Using BMI
For a man 5ft 11in (173 cm) tall, the healthy weight range is 55–74 kg (8 stone 8 lbs to 11 stone 8 lbs), which corresponds to a BMI between 18.5 and 24.9. This is the NHS healthy weight range for adult men at this height.
- Lower healthy weight bound: 55 kg (8st 8lbs) — BMI 18.5
- Upper healthy weight bound: 74 kg (11st 8lbs) — BMI 24.9
- Mid-range ideal weight: approximately 65 kg (10st 3lbs) — BMI 21.5
The average UK weight for men is approximately 85.7 kg, meaning many men are above the healthy weight range. Weight for height varies based on muscle mass—muscular men may have a higher weight but healthy body composition. The bmi healthy range is a useful screening tool, though it doesn't account for muscle versus fat. Your GP can provide personalised weight advice based on your overall health profile and any weight-related conditions you may have.

Using the BMI Calculator to Find Your Healthy Weight
To determine whether you fall within the healthy weight range at 5ft 11in, use our free healthy weight calculator above—it will instantly show your BMI and where you sit relative to NHS guidelines. Simply enter your height (173 cm) and your current weight, and the calculator will tell you whether you're in the healthy, overweight, or obese category.
If you're outside the healthy weight range, the calculator helps you understand what your target healthy weight might be. Even modest weight loss—around 5–10% of body weight—can deliver meaningful health benefits including improved blood pressure, better blood sugar control, and reduced joint strain. Your GP can discuss personalised weight management strategies with you if needed.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the healthy weight range for a 5ft 11in man?
The healthy BMI range (18.5–24.9) for a man 5ft 11in tall corresponds to approximately 55–74 kg (8st 8lbs to 11st 8lbs). This is based on NHS guidelines. The mid-range ideal weight is around 65 kg (10st 3lbs). Individual healthy weight depends on muscle mass and overall fitness.
How do I calculate my healthy weight using BMI?
Use the free BMI calculator on this page—enter your height (173 cm) and weight, and it will instantly calculate your BMI and show whether you're in the healthy range. A healthy BMI is 18.5–24.9. You can also use our free weight converter to switch between kg and stone.
What's the average weight for UK men at this height?
The average UK adult man weighs approximately 85.7 kg (13st 7lbs), which is above the healthy weight range. However, average doesn't mean healthy—many men are overweight according to BMI. Your personal healthy weight depends on your individual health, muscle mass, and medical history.
What if I'm above the healthy weight range?
If you're in the overweight or obese category, losing just 5–10% of body weight can improve health outcomes including blood pressure, cholesterol, and joint health. The NHS recommends weight loss of 0.5–1 kg per week. Speak to your GP about personalised strategies, including diet, exercise, or weight management support.
Is BMI the only measure of healthy weight?
BMI is a useful screening tool but has limitations—it doesn't distinguish between muscle and fat. Waist circumference is also important: men should aim for under 94 cm (37in) for reduced risk, or under 102 cm (40in) for increased risk. Your GP can assess your overall health holistically.
