Is 10 Stone Overweight?
Whether 10 stone is overweight depends on your height. The NHS uses BMI (Body Mass Index) to assess weight, and for most adults, 10 stone falls into the overweight range — though this varies. Using our free BMI calculator above, you can check your exact BMI instantly by entering your height and weight. This page explains what overweight means according to NHS guidelines and what it means for your health.

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.
NHS Overweight and Obese Thresholds
The NHS defines weight categories using BMI ranges, which are calculated from your weight and height:
- Healthy weight: BMI 18.5 to 24.9
- Overweight: BMI 25.0 to 29.9
- Obese (Class I): BMI 30.0 to 34.9
- Obese (Class II): BMI 35.0 to 39.9
- Severely obese (Class III): BMI 40.0 and above
At 10 stone (63.5kg), whether you're in the overweight or obese range depends entirely on your height. For example, at 5ft 4in (163cm), 10 stone gives a BMI of 26.9 — solidly overweight. At 5ft 10in (178cm), 10 stone gives a BMI of 22.3 — which is a healthy weight. This is why am I overweight cannot be answered without knowing your height.

Waist Measurement and Next Steps
BMI is a useful screening tool, but the NHS also recommends measuring your waist to get a fuller health picture. Overweight health risks are often linked to where fat is stored around your middle.
- Men: over 94cm (37in) = increased risk; over 102cm (40in) = high risk
- Women: over 80cm (31.5in) = increased risk; over 88cm (34.5in) = high risk
If you're concerned about your weight, start by calculating your BMI using the free calculator on this page, then speak to your GP. They can discuss your healthy weight range and whether support is needed. Even a 5–clinically studied weight loss can bring meaningful health benefits.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How do I know if 10 stone is overweight for me?
Use our free BMI calculator above with your height to find your exact BMI. The NHS defines overweight as BMI 25–29.9. At 10 stone, your BMI depends on your height — for most adults it will fall into the overweight range, but not always. Your GP can also advise on whether your weight is healthy for you individually.
What is the NHS overweight threshold?
According to NHS guidelines, an overweight BMI falls between 25.0 and 29.9. Below 18.5 is underweight, 18.5–24.9 is healthy weight, and 30.0+ is obese. For people of South Asian, Chinese, Black African, or Black Caribbean heritage, the thresholds are slightly lower due to higher health risks at lower BMI levels.
What health risks come with being overweight?
Overweight health risks include type 2 diabetes, high blood pressure, heart disease, sleep apnoea, and joint strain. However, being overweight does not assures these conditions, and weight is just one factor in overall health. Your GP can assess your individual risk and discuss what support might help.
If I'm overweight, what should I do?
Start by calculating your exact BMI and measuring your waist using the NHS guidance. A weight check NHS through your GP is a good next step — they can discuss your healthy weight range and offer practical support through NHS weight management services or lifestyle advice. Even modest weight loss (5–10%) can improve health outcomes.
How does 10 stone compare to average UK weight?
The average UK adult woman weighs about 71.6kg (11st 3lbs) and the average man weighs about 85.7kg (13st 7lbs). At 10 stone (63.5kg), you're below the UK average, but whether this is healthy depends entirely on your height. Use the BMI calculator to find your personal status.
