A 5′2″ (157 cm) woman has a healthy weight of 45.9–61.8 kg (7 st 3 lb to 9 st 10 lb), based on the NHS healthy BMI range of 18.5–24.9. The midpoint is about 55 kg (8 st 8 lb).

Healthy weight for a 5′2″ woman
A woman who is 5 ft 2 in (157 cm) tall has a healthy weight of 45.9 kg to 61.8 kg, or 7 st 3 lb to 9 st 10 lb. This is the weight range that gives a BMI of 18.5 to 24.9, which the NHS classes as healthy for most adults.
At 5′2″, you would be classed as overweight from about 62.0 kg (9 st 11 lb), and as having obesity from 74.4 kg (11 st 10 lb). If you are of South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean background, NICE advises a lower upper limit of BMI 22.9 – that is 56.8 kg (8 st 13 lb) at your height.
| BMI | Category | Kilograms | Stones | Pounds |
|---|---|---|---|---|
| BMI 18.5 | Lower healthy limit | 45.9 kg | 7 st 3 lb | 101 lb |
| BMI 20 | Healthy | 49.6 kg | 7 st 11 lb | 109 lb |
| BMI 22 | Healthy (midpoint) | 54.6 kg | 8 st 8 lb | 120 lb |
| BMI 24.9 | Upper healthy limit | 61.8 kg | 9 st 10 lb | 136 lb |

Ideal weight for a 5′2″ woman by age
The NHS healthy BMI range does not change between 18 and 64, so the healthy weight for a 5′2″ woman is the same at 25 as it is at 55. What does change is body composition: after about 30 we slowly lose muscle, and after the menopause fat tends to move towards the waist. That is why waist size becomes a more useful check as you get older.
| Age | Healthy weight | In stones |
|---|---|---|
| 18–64 | 45.9 – 61.8 kg | 7 st 3 lb – 9 st 10 lb |
| 65 and over* | 57.0 – 69.2 kg | 9 st 0 lb – 10 st 13 lb |
*For over-65s, a BMI of roughly 23 to 28 is linked with the lowest risk. Do not try to lose weight in later life without speaking to your GP.
Ideal weight formulas for 5′2″
Doctors and pharmacists sometimes use “ideal body weight” formulas, mainly to work out medicine doses. They give a single number rather than a range. For a 5′2″ woman they give:
| Formula | Ideal weight | Stones |
|---|---|---|
| Devine | 50.1 kg | 7 st 12 lb |
| Robinson | 52.4 kg | 8 st 4 lb |
| Miller | 55.8 kg | 8 st 11 lb |
| Hamwi | 49.9 kg | 7 st 12 lb |
| Average of formulas | 52.1 kg | 8 st 3 lb |
These formulas are a useful reference, but the NHS bases healthy weight on the BMI range, which allows for natural differences in build. Use our ideal body weight calculator for other heights.
Does frame size change your ideal weight?
Your frame (bone structure) can help you decide where in the healthy range you are likely to feel and look your best. A smaller frame usually sits towards the lower end, and a larger frame towards the upper end. Measure your wrist and use the body frame size calculator to find out.
| Frame size | Suggested part of range | Weight |
|---|---|---|
| Small | BMI 18.5–22 | 45.9 – 54.6 kg (7 st 3 lb – 8 st 8 lb) |
| Medium | BMI 20–24 | 49.6 – 59.5 kg (7 st 11 lb – 9 st 5 lb) |
| Large | BMI 21.5–24.9 | 53.3 – 61.8 kg (8 st 6 lb – 9 st 10 lb) |
How does a 5′2″ woman compare with the UK average?
The average woman in England is 162.3 cm (5 ft 4 in) tall and weighs 72.8 kg (11 st 6 lb), according to the Health Survey for England 2022. The average BMI is 27.6, which is in the overweight range, so “average” is not the same as “healthy”. See average weight for women in the UK.
Check your waist too. For a 5′2″ woman, a healthy waist is under 79 cm (31 in) – half your height (NICE).
