What BMI is 75kg? Convert to Stone and Check Health Category
If you weigh 75kg, your BMI depends entirely on your height — this is why height matters when assessing whether your weight is healthy. At 75kg, you could fall anywhere from a healthy weight to overweight category depending on how tall you are. Use our free BMI calculator above to find your exact BMI, or read on to see examples across different heights. We'll also show you the NHS weight categories and what 75kg equals in stone and pounds.

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.
75kg BMI at Different Heights
To convert 75kg to stone, divide by 6.35 — which gives approximately 11 stone 10 pounds (11st 10lbs). However, whether this weight is healthy depends entirely on your height. Here's what 75kg means for BMI at common UK heights:
- At 5ft 4in (163cm): BMI of 28.2 — overweight category
- At 5ft 6in (168cm): BMI of 26.6 — overweight category
- At 5ft 8in (173cm): BMI of 25.1 — overweight (just above healthy range)
- At 5ft 10in (178cm): BMI of 23.7 — healthy weight category
- At 6ft 0in (183cm): BMI of 22.4 — healthy weight category
The difference between overweight and healthy weight at 75kg is just a few centimetres of height. This is why the metric to imperial weight conversion alone (75kg to stone) doesn't tell the full story — height is essential.

NHS BMI Categories and When to Seek Advice
According to NHS guidelines, a healthy BMI is between 18.5 and 24.9. At 75kg, depending on your height, you may fall into the overweight (25.0–29.9) or healthy weight range. If your BMI at 75kg is 25 or above, your GP can offer practical support through NHS weight management programmes, which may include diet and exercise guidance, or referral to specialist services for additional support.
It's important to note that BMI has limitations — it doesn't distinguish between muscle and fat, so athletic individuals may have a higher BMI without health concerns. Your GP can give personalised advice based on your individual health context, family history, and any weight-related conditions you may have.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is 75kg in stone and pounds?
75kg converts to 11 stone 10 pounds (11st 10lbs). To calculate this, divide kilograms by 6.35 for stone, or multiply by 2.20462 for pounds. Our free weight converter on this page can do the calculation instantly for any weight.
Is 75kg a healthy weight?
It depends on your height. At 75kg, you could have a BMI ranging from about 22.4 (healthy) at 6ft tall to 28.2 (overweight) at 5ft 4in. Use our BMI calculator above to check your specific BMI based on your height.
What BMI should I aim for?
The NHS recommends a healthy BMI of 18.5 to 24.9 for most adults. For South Asian, Chinese, Black African, or Black Caribbean adults, the recommended range is 18.5 to 22.9. Your GP can advise on a target weight that's right for you.
If 75kg gives me an overweight BMI, what should I do?
Your GP can discuss sustainable weight loss options, including diet, exercise, and behavioural support through NHS weight management services. Even a 5–10% weight reduction can have meaningful health benefits. Your GP may refer you to specialist services if appropriate.
Why does BMI depend on height?
BMI is a ratio of weight to height squared. Two people weighing 75kg at different heights have very different body compositions — a taller person naturally has a lower BMI at the same weight, which is why height is crucial when interpreting BMI.
