Ideal Weight for a Man 5'10 — What's Healthy?
For a man who is 5'10 (178 cm), the healthy weight range is approximately 65–82 kg (10 stone 3 lbs to 12 stone 12 lbs) according to NHS guidelines. However, "ideal" weight varies based on muscle mass, frame size, and individual health factors. The average UK man is 5'9 and weighs around 85.7 kg, which falls slightly above the healthy weight range. Using our free BMI calculator above, you can determine your personal healthy weight target and see where you currently stand.

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 and BMI Context
For a man 5'10 tall, the healthy weight range according to NHS guidelines is 65–82 kg (10 stone 3 lbs to 12 stone 12 lbs). This corresponds to a BMI of 18.5 to 24.9, the NHS healthy weight category.
- Lower healthy limit: 65 kg (10 stone 3 lbs) — BMI 18.5
- Upper healthy limit: 82 kg (12 stone 12 lbs) — BMI 24.9
- Overweight threshold: 83 kg (13 stone 1 lb) — BMI 25.0
- Obese threshold: 112 kg (17 stone 8 lbs) — BMI 30.0
It's important to note that BMI is a screening tool and doesn't account for muscle mass — a muscular man may have a higher BMI but lower body fat. Use the weight converter on this page to see your weight in both metric and imperial units, then calculate your personal BMI to understand your individual health context.

Factors Affecting Your Ideal Weight
Ideal weight isn't one-size-fits-all. Several factors influence what's right for you:
- Muscle mass: Muscle weighs more than fat, so athletic men may weigh more but have lower body fat percentage
- Frame size: Larger-framed individuals naturally weigh more within a healthy range than smaller-framed men
- Age: Muscle naturally decreases with age, affecting metabolic rate and healthy weight targets
- Ethnicity: For men of South Asian, Chinese, Black African, or Black Caribbean heritage, NHS recommends assessing health risk at lower BMI thresholds (18.5–22.9 healthy range)
- Individual health conditions: Pre-diabetes, cardiovascular health, and other factors mean your GP may recommend a specific target weight for your circumstances

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What's the ideal weight for a 5'10 man according to NHS guidelines?
The NHS healthy weight range for a man 5'10 is approximately 65–82 kg (10 stone 3 lbs to 12 stone 12 lbs), corresponding to a BMI of 18.5–24.9. Individual factors like muscle mass and frame size mean the ideal weight within this range varies per person.
Is there a difference between ideal weight and average weight?
Yes. Average UK male weight is around 85.7 kg (13 stone 7 lbs), which is above the healthy range. Ideal weight refers to the health-optimal range for your height, not what most people weigh. The two are different.
How can I find my personal ideal weight target?
Use our free BMI calculator above to enter your current weight and height — it will show your BMI category and healthy weight range. Then discuss a personal target with your GP, who can consider your muscle mass, frame size, and health conditions.
Does muscle mass affect ideal weight calculations?
Yes significantly. BMI doesn't distinguish muscle from fat, so a muscular man may have a higher BMI than recommended but lower body fat percentage. Body composition matters more than the number on the scale for health.
Should men of different ethnic backgrounds use different ideal weight ranges?
Yes. The NHS recommends that South Asian, Chinese, Black African, and Black Caribbean men use a lower healthy weight threshold (BMI 18.5–22.9 rather than 18.5–24.9) due to higher cardiovascular and diabetes risk at the same BMI.
