Female Weight Chart — UK Health Guide
A female weight chart helps you understand healthy weight ranges for your height and compare your current weight against NHS guidelines. In the UK, healthy weight is typically defined by BMI (body mass index) between 18.5 and 24.9, though individual factors like age, muscle mass, and ethnicity affect what's healthy for you personally. This guide provides UK weight benchmarks and explains how to use them alongside health management tools. Remember that weight is just one measure of health — your GP can give personalised advice about what's healthy for you.

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 by Height (UK Female)
The table below shows healthy weight ranges for UK adult women at different heights, based on a BMI of 18.5 to 24.9. These are approximate ranges — individual variation is normal and healthy.
- 5ft 0in (152cm): 47–63 kg (7st 6lbs – 9st 13lbs)
- 5ft 2in (157cm): 51–68 kg (8st 0lbs – 10st 10lbs)
- 5ft 4in (163cm): 54–72 kg (8st 6lbs – 11st 5lbs)
- 5ft 6in (168cm): 57–76 kg (8st 13lbs – 11st 13lbs)
- 5ft 8in (173cm): 60–81 kg (9st 6lbs – 12st 10lbs)
- 5ft 10in (178cm): 64–85 kg (10st 1lbs – 13st 5lbs)
Use our free BMI calculator above to find your exact healthy weight range based on your height. These figures assume a healthy BMI for the general UK population — if you're of South Asian, Chinese, Black African, or Black Caribbean heritage, the NHS recommends slightly lower thresholds.

Understanding BMI and Weight Categories
BMI (body mass index) is calculated as weight (kg) divided by height (m) squared. It helps identify whether someone is underweight, healthy weight, overweight, or obese. According to NHS guidance, a healthy BMI for women is 18.5–24.9.
- Underweight: BMI below 18.5
- Healthy weight: BMI 18.5–24.9
- Overweight: BMI 25.0–29.9
- Obese: BMI 30.0 and above
However, BMI has limitations — it doesn't distinguish muscle from fat, and waist measurement is also important. If your BMI is outside the healthy range, your GP can discuss personalised weight management options, including lifestyle changes or, where appropriate, prescription weight loss treatment alongside diet and exercise.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the healthy weight for a woman 5ft 5in tall?
For a woman 5ft 5in (165cm) tall, a healthy weight range is approximately 53–71 kg (8st 5lbs – 11st 2lbs), based on a BMI of 18.5–24.9. Individual factors like muscle mass and bone density affect what's ideal for you. Use our free BMI calculator to calculate your personal healthy range.
Is a weight chart the same for all adult women?
Weight charts provide general guidance, but healthy weight varies based on height, age, muscle mass, genetics, and ethnicity. The NHS recommends lower BMI thresholds for some ethnic groups due to higher health risks at the same BMI. Your GP can give you personalised weight guidance.
How often should women weigh themselves?
There's no single recommendation — it depends on your goals. Some people find weekly weigh-ins helpful for weight management; others prefer monthly checks to avoid daily fluctuations. Weight naturally varies by 1–2 kg day-to-day due to water retention and digestion. A progress tracker can help you spot longer-term trends.
What is the average weight for a UK adult woman?
According to recent UK health data, the average adult woman weighs approximately 71.6 kg (11st 3lbs) and stands 161.6 cm (5ft 3.5in) tall. However, "average" doesn't mean "healthy" — healthy weight depends on individual height, frame, and health status, not population averages.
Can weight charts be used to diagnose health problems?
No. Weight charts show whether someone is in a healthy BMI range, but BMI alone doesn't diagnose health conditions. Your GP uses BMI alongside blood pressure, cholesterol, blood sugar, waist measurement, medical history, and symptoms to assess your overall health. Always consult your GP for health advice.
