Is 68kg a Healthy Weight? Depends on Your Height
68kg is equivalent to 10 stone 10.7 pounds in UK measurements. Whether this weight in stone is healthy for you depends entirely on your height, age, and individual health profile. The NHS uses BMI (body mass index) as a screening tool to assess weight health — not weight alone. Use our free BMI calculator above to check your personal BMI instantly and see where you fall in the healthy range. The same weight can be perfectly healthy for one person and overweight for another, depending on how tall you are.

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 at Different Heights
At 68kg, your weight falls into different BMI categories depending on your height. Here's how the NHS healthy weight ranges work:
- At 5ft 4in (163cm): 68kg gives a BMI of 25.3 — just above the healthy range (overweight category). Healthy weight at this height: 47–64kg (7st 5lbs–10st 1lbs).
- At 5ft 8in (173cm): 68kg gives a BMI of 22.8 — solidly in the healthy range. Healthy weight at this height: 55–74kg (8st 9lbs–11st 8lbs).
- At 5ft 11in (180cm): 68kg gives a BMI of 20.9 — comfortably healthy. Healthy weight at this height: 60–81kg (9st 6lbs–12st 11lbs).

What the NHS Says About Healthy Weight
The NHS defines a healthy BMI as 18.5 to 24.9 for adults. At 68kg, whether you're in this range depends entirely on your height. The NHS also recommends checking your waist measurement — increased health risk begins at over 94cm (37 inches) for men and 80cm (31.5 inches) for women, regardless of BMI. If your weight is above the healthy range for your height, losing even 5–10% of body weight can bring real health benefits. Your GP can give you personalised guidance on whether your current weight is healthy for you, and discuss any weight management support if needed.
