What's the Ideal Weight for a 5'11" Man?
For a man who is 5'11" (180 cm), the ideal weight range according to NHS guidelines is approximately 65–87 kg (10 stone 3 lbs to 13 stone 10 lbs). This range corresponds to a healthy BMI of 18.5 to 24.9, which is the standard used across the UK to assess whether weight falls within a healthy range for height. However, ideal body weight can vary depending on factors like muscle mass, bone density, and overall fitness level. Your GP can help you determine what weight is healthiest for your individual circumstances.

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" Using BMI
The NHS uses BMI (body mass index) to define a healthy weight range for any given height. For a 5'11" man, this translates to a BMI between 18.5 and 24.9.
- Lower healthy weight bound: approximately 65 kg (10 stone 3 lbs) — BMI 18.5
- Upper healthy weight bound: approximately 87 kg (13 stone 10 lbs) — BMI 24.9
- Average UK weight for men: around 85.7 kg (13 stone 7 lbs), though this is in the overweight range when height is factored in
This weight for height UK framework helps assess health risk. Men falling above 87 kg at this height enter the overweight category (BMI 25–29.9), whilst those above 110 kg move into the obese range. Use our free BMI calculator above to check your personal BMI instantly and see exactly where your weight falls on the NHS scale.

Using the Healthy Weight Calculator for Your Height
The healthy weight calculator is the most practical way to determine your ideal weight range. Rather than relying on generalised tables, you can input your exact height and see your personalised healthy weight zone based on NHS BMI thresholds. Try the BMI calculator on this page to calculate your healthy weight instantly.
Remember that ideal weight isn't just a single number — it's a range. Two men at 5'11" with identical BMI can have different body compositions if one has more muscle mass than the other. If you're unsure whether your current weight is healthy for you, your GP can assess your individual health profile and advise accordingly.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What BMI should a 5'11" man aim for?
According to NHS guidelines, a healthy BMI for any adult is 18.5 to 24.9. For a 5'11" man, this equates to approximately 65–87 kg (10 stone 3 lbs to 13 stone 10 lbs). Calculate your personal BMI using our free BMI calculator above.
Is 85 kg a good weight for a 5'11" man?
At 85 kg and 5'11", your BMI would be approximately 11.9, which falls into the overweight category (BMI 25–29.9). Aiming for under 87 kg would bring you within the healthy weight range according to NHS standards.
What's the average UK weight for men this height?
The average UK man weighs approximately 85.7 kg (13 stone 7 lbs), though this varies significantly. However, when combined with average height, the average UK adult man's BMI is around 27.9, which is classified as overweight.
How do I calculate my ideal weight range?
Use the NHS BMI formula: BMI = weight (kg) ÷ height (metres)². For a healthy BMI of 18.5–24.9, multiply these values by your height squared. Our weight converter and BMI calculator above make this instant and accurate.
Does ideal weight differ for muscular men?
Yes. BMI doesn't distinguish between muscle and fat, so athletic or muscular men may have a higher BMI whilst maintaining low body fat. Your GP or a fitness professional can assess body composition beyond BMI alone if this applies to you.
