Is 11 Stone 12 Pounds a Healthy Weight?
11 stone 12 pounds (75 kg) is a moderate weight for most adults, but whether it's healthy depends entirely on your height. A weight that's healthy for someone 5ft 10in could be overweight for someone 5ft 2in. The NHS uses BMI (Body Mass Index) as the primary screening tool to assess if a weight falls in a healthy range. Using our free weight converter and BMI calculator above, you can check exactly where your weight sits and what the NHS considers healthy for your specific height.

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 for Different Heights
To understand if 75 kg (11 stone 12 pounds) is healthy for you, find your height in this table. The figures show the healthy weight range according to NHS guidelines (BMI 18.5–24.9). Notice how the same weight can be healthy at one height but overweight at another:
- 5ft 2in (157 cm): healthy range 47–62 kg (7st 5lbs–9st 10lbs) — 75 kg is overweight
- 5ft 6in (168 cm): healthy range 52–70 kg (8st 2lbs–11st 0lbs) — 75 kg is slightly overweight
- 5ft 10in (178 cm): healthy range 59–78 kg (9st 3lbs–12st 4lbs) — 75 kg is in the healthy range
- 6ft 1in (185 cm): healthy range 63–84 kg (9st 13lbs–13st 3lbs) — 75 kg is in the healthy range
BMI is a useful screening tool, but it has limitations—it doesn't distinguish between muscle and fat, so a fit, muscular person may have a higher BMI than expected. Use the BMI calculator on this page to get your personal result.

NHS Guidance: Beyond Weight Alone
The NHS doesn't focus on weight alone. Even if your BMI sits in the healthy range, waist circumference also matters for health risk assessment. Men should aim for a waist below 94 cm (37 inches); women below 80 cm (31.5 inches). If 11 stone 12 pounds puts you outside a healthy weight range for your height, or if you have health concerns, speak to your GP. They can assess your individual situation, discuss lifestyle changes, or recommend support like structured weight management programmes. Weight management is a marathon, not a sprint—sustainable changes to diet and activity tend to work best long-term.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 11 stone 12 pounds in kilograms?
11 stone 12 pounds equals 75 kg. To convert stone to kg manually, divide the total pounds by 2.20462. You can also use our free weight converter above to switch instantly between stone, pounds, and kilograms.
Is 75 kg overweight or healthy?
It depends on your height. At 5ft 10in, 75 kg is healthy (BMI 24.2). At 5ft 6in, it's slightly overweight (BMI 27.2). Use our BMI calculator to check your personal result based on your exact height.
How do I know if my weight is healthy?
The NHS uses BMI as a screening tool. A healthy BMI is 18.5–24.9 for most adults. However, for adults of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends a lower threshold of 18.5–22.9. Your GP can also assess your waist circumference and overall health picture.
What should I do if I'm outside the healthy weight range?
Start with lifestyle changes: gradual diet improvements and increased physical activity. Your GP can refer you to NHS weight management services (tier 1–4), which offer behaviour change support and, where appropriate, prescription medication alongside lifestyle work.
Is BMI the only measure of health?
No. BMI is a useful screening tool but doesn't account for muscle mass, bone density, or where fat is stored. Waist circumference is also important—excess abdominal fat carries higher health risks. Your GP can provide a full health assessment tailored to you.
