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.

Is 71kg a Healthy Weight? BMI & Health Context
Whether 71kg is a healthy weight depends entirely on your height. Using our free BMI calculator, you can check your exact BMI at this weight instantly. For example, at 5ft 6in (168cm), a weight of 71kg gives a BMI of 25.2 — just into the overweight category according to NHS guidelines. At 5ft 10in (178cm), the same weight gives a BMI of 22.8 — within the healthy weight range.
The NHS recommends a healthy BMI between 18.5 and 24.9 for most adults. If you're concerned about your weight or have weight-related health conditions, your GP can provide personalised advice and discuss whether weight management support is appropriate for your situation.
