Ideal Weight for a Woman 5'10" — NHS BMI Guide
At 5'10" (178 cm), a woman's ideal body weight falls within a specific healthy range based on NHS BMI guidelines. Rather than a single "ideal" number, health authorities recommend a healthy weight range of approximately 55 to 74 kg (8 stone 9 lbs to 11 stone 9 lbs). This range corresponds to a BMI of 18.5 to 24.9, which the NHS recognises as healthy for most adults. Your actual ideal weight depends on factors like muscle mass, frame size, and overall health — not just height alone.

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 Range for a 5'10" Woman Using BMI
The NHS healthy weight range for a woman 5'10" (178 cm) tall is approximately 55 to 74 kg (8st 9lbs to 11st 9lbs). This is calculated using the BMI formula: weight (kg) ÷ height (m)².
A BMI between 18.5 and 24.9 is considered healthy for most adults. At 178 cm, this translates to:
- Lower healthy bound: 18.5 × (1.78)² = 55.4 kg (8st 10lbs)
- Upper healthy bound: 24.9 × (1.78)² = 78.8 kg (12st 5lbs)
However, BMI has limitations — it doesn't distinguish between muscle and fat. A woman with high muscle mass might have a higher BMI but excellent health. Your GP can provide personalised guidance about what weight is right for your individual circumstances. Use our free BMI calculator above to determine your personal BMI and see where you fall within the healthy range.

Important Context: BMI Isn't the Whole Picture
While a healthy weight range for height is useful, the NHS also recommends measuring waist circumference alongside BMI. For women, a waist measurement above 80 cm (31.5 inches) indicates increased health risk, regardless of BMI. Factors like age, family history, fitness level, and existing health conditions also matter. Our free weight converter can help you track your weight in stone, pounds, or kilograms — whichever you prefer. The most important step is discussing your personal healthy weight target with your GP, especially if you have underlying health conditions or are considering significant weight changes.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
What is the ideal weight for a 5'10" woman?
The ideal weight range for a 5'10" (178 cm) woman, based on NHS BMI guidelines, is approximately 55 to 75 kg (8st 9lbs to 11st 10lbs). However, "ideal" varies by individual — muscle mass, frame size, and genetics all play a role. Your GP can advise on your personal healthy weight target.
Is 70 kg a healthy weight for a woman 5'10"?
Yes, 70 kg (11st) is well within the healthy BMI range for a woman 5'10" tall. This weight gives a BMI of approximately 22.1, which falls squarely in the NHS healthy range of 18.5–24.9. Individual health depends on more than weight alone.
How do I calculate my own healthy weight range?
Use the BMI formula: weight (kg) ÷ height (m)². A healthy BMI is 18.5–24.9. Alternatively, use our free BMI calculator on this page — it instantly shows your BMI and healthy weight range for your height and demographic.
Does BMI tell the whole story about health?
No. BMI is a useful screening tool but has limitations — it doesn't account for muscle mass, bone density, or where fat is stored. Waist circumference and overall fitness are also important. Always discuss your personal health with your GP for complete guidance.
What if I'm not sure what my ideal weight should be?
Schedule a conversation with your GP. They can assess your individual health, family history, and any conditions you have to recommend a personalised healthy weight range. Health is individual, not one-size-fits-all. ```
