Weight Table by Height — Find Your Healthy Range
A weight table by height shows the healthy weight range for adults at different heights, based on BMI and NHS guidelines. Your ideal weight depends on your height, not just a single number — this guide shows you exactly where you fall within the healthy weight range for your height in UK measurements (stone, lbs, and kg). Understanding your healthy weight range is the first step toward effective weight management.

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 Ranges by Height (UK)
Healthy weight ranges are based on a BMI of 18.5 to 24.9, which the NHS recommends for adults. The table below shows the healthy weight range for common UK heights. Remember that these are guidelines — your ideal weight may vary depending on your age, muscle mass, frame size, and overall health.
- 5ft 0in (152cm): 7st 7lbs – 10st 2lbs (47–65 kg)
- 5ft 4in (163cm): 8st 7lbs – 11st 7lbs (54–73 kg)
- 5ft 8in (173cm): 8st 10lbs – 11st 10lbs (55–74 kg)
- 5ft 10in (178cm): 9st 4lbs – 12st 7lbs (59–80 kg)
- 6ft 0in (183cm): 10st 0lbs – 13st 5lbs (63–85 kg)
Use our free BMI calculator above to check your personal BMI and see exactly where you fall within these ranges. If you're above the healthy weight range, losing even 5–10% of your body weight can improve your health.

Why Height Matters for Weight Management
Height is crucial because BMI — the standard measure used by the NHS — divides weight by height squared. Two people weighing the same may have very different BMIs and health risks based on their height. A weight that is healthy for someone 6ft tall would be overweight for someone 5ft 2in. This is why weight tables by height are more useful than single target weights.
Our free weight converter helps you switch between kg, stone, and lbs instantly, making it easy to find your weight in your preferred unit. For personalised weight management advice, consult your GP or use our GLP-1 weight loss calculator if you're interested in understanding medication options.
If you're concerned about your weight, remember that sustainable weight loss happens at about 0.5–1 kg per week through a combination of reduced-calorie diet and increased physical activity. Your GP can provide personalised advice based on your health, medical history, and individual circumstances. Weight management is not just about reaching a number — it's about building healthy habits and improving your overall health outcomes.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I find my healthy weight range using a weight table?
Find your height in the table, then look at the weight range shown for that height. This range represents a BMI of 18.5 to 24.9, which the NHS considers healthy for most adults. If you fall within this range, your weight is considered healthy. If you're above or below, your GP can advise you on next steps.
Is the same weight healthy for everyone at my height?
No. Weight tables show general ranges based on BMI, but individual healthy weight varies by age, muscle mass, bone density, frame size, and overall fitness. Athletes may be heavier due to muscle. Your GP can help determine what's healthy specifically for you.
What if I'm South Asian, Black African, or Black Caribbean?
The NHS recommends lower BMI thresholds for these populations due to higher health risks at the same BMI levels. Instead of 18.5–24.9, the healthy range is approximately 18.5–22.9. Consult your GP or use our BMI calculator, which can adjust for ethnicity.
How much weight should I lose if I'm above the healthy range?
The NHS recommends losing 0.5–1 kg per week for sustainable results. Start with a moderate calorie deficit of around 500 kcal per day. Your GP can advise on safe, personalised targets based on your health. gradual weight management can increase muscle loss and isn't usually recommended without medical supervision.
Can I use this table if I have a medical condition affecting my weight?
Yes, but consult your GP first. Conditions like thyroid disease, PCOS, and diabetes can affect healthy weight ranges and weight loss. Your GP can provide personalised guidance and may refer you to a specialist weight management service if needed.
