Average Weight in the UK in Stone
Based on Health Survey for England data: the average man weighs about 13 st 3 lb, the average woman about 11 st 0 lb.
Where the Numbers Come From
These figures come from the Health Survey for England (HSE), an annual survey commissioned by NHS England that physically measures a representative sample of adults. Unlike self-reported surveys, HSE uses calibrated scales, so the numbers are reliable. The Office for National Statistics (ONS) publishes related population health data drawing on the same sources.
Figures are rounded to the nearest pound for readability and converted at 1 stone = 14 lb = 6.35029 kg. Exact survey means vary slightly year to year.
Average Weight by Age Group
Weight typically rises through middle age and falls slightly after 65. These are approximate means:
| Age Group | Men (avg) | Women (avg) |
|---|---|---|
| 16-24 | 12 st 4 lb | 10 st 2 lb |
| 25-34 | 13 st 1 lb | 10 st 11 lb |
| 35-44 | 13 st 6 lb | 11 st 2 lb |
| 45-54 | 13 st 8 lb | 11 st 4 lb |
| 55-64 | 13 st 7 lb | 11 st 3 lb |
| 65-74 | 13 st 3 lb | 11 st 0 lb |
| 75+ | 12 st 8 lb | 10 st 6 lb |
Approximate means derived from HSE measured data, converted to stone. Individual variation is wide.
The Trend: Getting Heavier
Average adult weight in England has risen steadily since the 1990s. In 1993, around 15 percent of adults were obese (BMI 30+); recent HSE reports put the figure above 25 percent, with roughly two-thirds of adults overweight or obese. Mean weight has risen by several kilograms over the same period.
Being above average is not automatically unhealthy, and being below it is not automatically healthy. What matters is your BMI relative to your height. Check the ideal weight chart in stone or use our BMI calculator for your personal figure.
Context matters: the "average" includes all adults, including the growing share who are obese. Health guidance is based on BMI categories, not on matching the average. The average tells you where you stand relative to the population; the BMI chart tells you where you stand relative to health.
