What Is 75kg in Stone and What's Your BMI?
75kg converts to 11 stone and 11 pounds in UK measurements. However, your BMI at this weight depends entirely on your height. The same weight can put you in the healthy range for a tall person or the overweight category for someone shorter. Use our free BMI calculator above to find your exact BMI, then check where you fall according to NHS guidelines.

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
Your BMI at 75kg varies significantly by height. Here are examples across common UK heights:
- 5ft 2in (157cm): BMI 30.5 — Obese (Class I)
- 5ft 5in (165cm): BMI 27.5 — Overweight
- 5ft 8in (173cm): BMI 25.2 — Overweight (just above healthy range)
- 5ft 10in (178cm): BMI 23.7 — Healthy weight
- 6ft 0in (183cm): BMI 22.4 — Healthy weight
- 6ft 2in (188cm): BMI 21.2 — Healthy weight
To convert kilograms to stone accurately for your own height, calculate your BMI using our weight converter and BMI calculator tools on this page to get your precise category.

Understanding Your BMI Category
The NHS defines BMI ranges as:
- Under 18.5 — Underweight
- 18.5–24.9 — Healthy weight
- 25.0–29.9 — Overweight
- 30.0–34.9 — Obese (Class I)
- 35.0–39.9 — Obese (Class II)
- 40+ — Severely obese (Class III)
BMI is useful but has important limitations: it doesn't distinguish muscle from fat, and waist circumference also matters for health risk. For people of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends lower BMI thresholds. Your GP can discuss what your BMI means for your individual health.
