Healthy Weight For A 6 Foot Man
If you're 6 foot (183 cm) tall, the NHS healthy weight range for you is approximately 68 to 91 kg, or 10 stone 10 lbs to 14 stone 4 lbs. This range is based on achieving a healthy BMI between 18.5 and 24.9, which the NHS recommends for adults. Your exact ideal weight depends on your age, muscle mass, and overall health. Use our free BMI calculator above to check your personal BMI instantly and discover where you currently fall within the healthy weight range.

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.
BMI-Based Healthy Weight Range For 6 Foot Men
For an adult man who is 6 foot (183 cm) tall, a healthy BMI of 18.5 to 24.9 translates to a weight range of approximately 68 to 91 kg (10 stone 10 lbs to 14 stone 4 lbs). According to NHS guidelines, this range supports good health and reduces the risk of weight-related conditions. The lower end (68 kg) represents a healthy weight for a leaner frame, whilst the upper end (91 kg) is healthy for someone with greater muscle or bone density.
- Underweight: Below 68 kg (under 10 stone 10 lbs) — BMI below 18.5
- Healthy weight: 68–91 kg (10 stone 10 lbs to 14 stone 4 lbs) — BMI 18.5–24.9
- Overweight: 91–109 kg (14 stone 4 lbs to 17 stone 2 lbs) — BMI 25.0–29.9
- Obese: Above 109 kg (above 17 stone 2 lbs) — BMI 30.0 or higher
These thresholds apply to most UK men. However, men of South Asian, Chinese, Black African, or Black Caribbean heritage may have different health thresholds — your GP can provide personalised guidance based on your ethnicity and individual health profile.

How To Calculate Your Personal Healthy Weight Range
The easiest way to discover your ideal weight is to calculate your BMI using your current weight and height. Our free BMI calculator on this page does this instantly — simply enter your height in feet and inches, your weight in stone or kg, and see your BMI result and how it compares to the healthy range.
Remember that healthy weight is a range, not a fixed number. Factors like muscle mass, bone density, fitness level, and age all influence your ideal weight within that range. If you're tracking progress towards a healthier weight, our free progress tracker helps you log changes over time and stay motivated. For personalised advice about what healthy weight means for your specific circumstances, speak with your GP.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
Is 6 foot considered average height for a UK man?
The average UK adult man is approximately 175 cm (5 foot 9 inches) tall. At 6 foot (183 cm), you are above average — around 8 cm taller than the UK mean. This affects your healthy weight range, which is larger than for shorter men. Height is one of the key factors the NHS uses to calculate healthy weight ranges.
What's the difference between healthy weight and ideal weight?
Healthy weight is a range (for you: 68–91 kg) where your BMI falls within 18.5–24.9, supporting good health. Ideal weight is more subjective — it depends on your personal goals, muscle mass, and frame. Both you and your GP should consider the healthy range rather than aiming for one exact number.
Should I use different healthy weight targets if I'm muscular?
BMI has limitations — it doesn't distinguish between muscle and fat. If you're very muscular or athletic, your BMI might fall outside the healthy range even though your body composition is healthy. Your GP or a healthcare professional can assess body composition more thoroughly using waist measurements and other methods.
Can I use the average UK weight as a target?
The average UK adult man weighs approximately 85.7 kg (13 stone 7 lbs). However, average doesn't mean healthy — many UK adults are overweight or obese. The NHS healthy weight range (68–91 kg for your height) is a better target based on health outcomes, not population averages.
What should I do if I'm outside the healthy weight range?
If your weight is significantly above or below the healthy range, speak with your GP. They can assess your individual health, discuss any underlying causes, and suggest appropriate steps — whether that's lifestyle changes, dietary support, or referral to specialist services. Small changes in weight can make meaningful health improvements.
