Have you ever found yourself wondering, “What should I actually weigh?” You’re not alone. It’s one of the most common questions people ask, yet the answer is rarely straightforward.
The truth is, there’s no single “perfect” number on the scale that works for everyone. Your ideal weight depends on a variety of factors — your height, age, gender, body frame, and even muscle mass all play a role. What’s healthy for one person might not be for another, which is why understanding the bigger picture is so important.
In this guide, we’ll break down everything you need to know about ideal height and weight charts for men and women by age. We’ll explore the different methods for calculating your healthy weight range, look at what changes as you get older, and share practical tips for maintaining a weight that supports your overall well-being.
What Exactly Is “Ideal Weight”?
Before we dive into the charts, let’s clarify what we mean by “ideal weight.”
The ideal weight is not a fixed number — it’s a range that is proportional to your height and age, and it aims to support your general health without increasing your risk of conditions associated with being overweight or underweight. It’s about finding a weight that helps you feel your best and reduces your risk of chronic diseases.
Historically, ideal weight charts were developed using data from life insurance companies, which correlated weight with longevity. Today, healthcare professionals use a combination of tools to assess healthy weight, including:
- Body Mass Index (BMI)
- Height-weight charts
- Waist circumference
- Body fat percentage
Each method has its strengths and limitations, which is why it’s helpful to look at the full picture rather than relying on a single number.
The Most Common Methods for Calculating Ideal Weight
Body Mass Index (BMI)
BMI is the most widely used screening tool for assessing weight status. It’s calculated by dividing your weight in kilograms by the square of your height in meters.
Here’s how the categories break down:
| BMI Range | Category |
|---|---|
| Less than 18.5 | Underweight |
| 18.5 – 24.9 | Normal / Healthy Weight |
| 25.0 – 29.9 | Overweight |
| 30.0 or more | Obese |
While BMI is a useful starting point, it has limitations. It doesn’t distinguish between muscle and fat, so an athlete with high muscle mass might have a BMI that categorises them as overweight despite being in excellent health. It also doesn’t account for age or gender differences in body composition.
The Devine Formula
The Devine formula is another common method, often used in clinical settings:
- For men: Ideal weight = 50 kg + 0.9 kg for every centimetre above 152 cm
- For women: Ideal weight = 45.5 kg + 0.9 kg for every centimetre above 152 cm
This formula provides a quick estimate but, like BMI, doesn’t account for frame size or muscle mass.
The Broca Index
A simpler approach is the Broca index:
- For those under 40: Ideal weight (kg) = height (cm) – 110
- For those over 40: Ideal weight (kg) = height (cm) – 100
While easy to remember, this method is quite general and doesn’t account for many individual factors.
The Frame Size Method
Another approach considers your body frame size — small, medium, or large. This method acknowledges that people with larger frames naturally have more bone density and lean mass, so their ideal weight is higher.
For example, a 5’6″ woman with a small frame might have an ideal weight range of 120–133 lbs, while a woman of the same height with a large frame might range from 140–159 lbs.
Height and Weight Chart by Age and Gender
One of the most practical tools is the height and weight chart, which gives you a quick visual reference for healthy weight ranges based on your height.
Chart: Ideal Weight Range by Height (Adults)
Based on a normal BMI of 19–24, here are the healthy weight ranges for adults:
| Height | Weight Range |
|---|---|
| 4’10” | 91 – 115 lbs |
| 4’11” | 94 – 119 lbs |
| 5’0″ | 97 – 123 lbs |
| 5’1″ | 100 – 127 lbs |
| 5’2″ | 104 – 131 lbs |
| 5’3″ | 107 – 135 lbs |
| 5’4″ | 110 – 140 lbs |
| 5’5″ | 114 – 144 lbs |
| 5’6″ | 118 – 148 lbs |
| 5’7″ | 121 – 153 lbs |
| 5’8″ | 125 – 158 lbs |
| 5’9″ | 128 – 162 lbs |
| 5’10” | 132 – 167 lbs |
| 5’11” | 136 – 172 lbs |
| 6’0″ | 140 – 177 lbs |
| 6’1″ | 144 – 182 lbs |
| 6’2″ | 148 – 186 lbs |
| 6’3″ | 152 – 192 lbs |
Chart: Ideal Weight by Height (Men and Women)
Another useful chart breaks down ideal weight ranges by height for men and women separately:
| Height (cm) | Men (kg) | Women (kg) |
|---|---|---|
| 147.3 (4’10”) | 44 – 54 | 41 – 52 |
| 152.4 (5’0″) | 47 – 58 | 43 – 55 |
| 157.5 (5’2″) | 50 – 62 | 46 – 59 |
| 162.6 (5’4″) | 53 – 66 | 49 – 63 |
| 167.6 (5’6″) | 56 – 70 | 53 – 67 |
| 172.7 (5’8″) | 60 – 74 | 56 – 71 |
| 177.8 (5’10”) | 64 – 79 | 59 – 75 |
| 182.9 (6’0″) | 67 – 83 | 63 – 80 |
| 187.9 (6’2″) | 71 – 88 | 66 – 84 |
| 190.5 (6’3″) | 73 – 90 | 68 – 86 |
How Age Affects Your Ideal Weight
Age is another important factor. As we get older, our metabolism naturally slows down, and our body composition changes — we tend to lose muscle mass and gain fat. This means that what was a healthy weight at 25 might not be the same at 55.
Here’s a general guide to weight ranges by age group:
| Age Group | Men (up to) | Women (up to) |
|---|---|---|
| 19 – 29 | 83.4 kg | 73.4 kg |
| 30 – 39 | 90.3 kg | 76.7 kg |
| 40 – 49 | 90.9 kg | 76.2 kg |
| 50 – 60 | 91.3 kg | 77.0 kg |
It’s worth noting that these are upper limits rather than targets — the healthiest weight for you will depend on your height, frame, and overall health profile.

Why Age Matters More Than You Think
You might have noticed that many ideal weight charts are designed for adults between 25 and 60 years old. That’s because weight tends to fluctuate during different life stages:
In your 20s and 30s, your metabolism is generally at its peak. This is the time when maintaining a healthy weight is often easiest, but it’s also when many people establish habits that will affect them for decades.
In your 40s and 50s, hormonal changes — particularly for women during perimenopause and menopause — can lead to weight gain, especially around the abdomen. Men also experience a gradual decline in testosterone, which can reduce muscle mass and slow metabolism.
In your 60s and beyond, maintaining muscle mass becomes increasingly important for mobility and overall health. The focus often shifts from weight loss to maintaining strength and preventing frailty.
Some experts even suggest that for older adults, a slightly higher BMI (up to 27) may be protective, as it provides reserves that can be helpful during illness.
Beyond the Scale: Other Factors to Consider
While height and weight charts are useful, they don’t tell the whole story. Here are a few other important considerations:
Body Frame Size
As mentioned earlier, frame size matters. If you have a larger frame, your ideal weight will naturally be higher than someone of the same height with a smaller frame. The charts above that include frame size adjustments give a more accurate picture.
Muscle Mass
Muscle weighs more than fat, so athletes and people who strength train regularly may weigh more while still being incredibly healthy. If you have high muscle mass, BMI and standard charts might overestimate your health risk.
Waist-to-Hip Ratio
Where you carry your weight is just as important as how much you weigh. Fat stored around the abdomen (visceral fat) is associated with a higher risk of heart disease, stroke, and diabetes.
A waist-to-hip ratio greater than 0.95 for men or 0.8 for women indicates an increased risk of disease. If you’re curious about your own ratio, check out the Ideal Waist-to-Hip Ratio Women Calculator.
Overall Health Markers
Blood pressure, cholesterol levels, blood sugar, and physical fitness are all important indicators of health that go beyond what the scale can tell you. A person at a “healthy” weight who has high blood pressure and poor diet may be at greater risk than someone slightly overweight who exercises regularly and eats well.
What If Your Weight Is Outside the “Ideal” Range?
First, don’t panic. A chart is a guide, not a verdict. If your weight falls outside the healthy range, it’s a signal to pay attention — not a reason to feel discouraged.
If you’re underweight, focus on nutrient-dense foods that help you build strength and maintain energy. If you’re overweight or obese, even modest weight loss — just 5% to 10% of your initial body weight — can significantly improve your health and reduce disease risk.
A good place to start is by understanding your daily calorie needs and creating a sustainable plan. The Free Weight Loss Calculator Online can help you determine your calorie target and estimate a realistic timeline for reaching your goals.
Practical Tips for Maintaining a Healthy Weight
Whether you’re looking to lose, gain, or maintain, these principles apply to everyone:
1. Prioritise protein. Protein helps preserve muscle mass during weight loss and keeps you feeling full longer.
2. Eat plenty of fibre. Vegetables, fruits, whole grains, and legumes support digestion and help control appetite.
3. Stay hydrated. Water supports metabolism and can help prevent overeating.
4. Move your body regularly. Aim for a mix of cardiovascular exercise and strength training.
5. Get enough sleep. Poor sleep disrupts the hormones that regulate hunger and metabolism.
6. Manage stress. Chronic stress can lead to emotional eating and weight gain.
7. Be patient. Sustainable weight management takes time. Focus on progress, not perfection.

When to See a Doctor
While charts and calculators are great starting points, there are times when professional guidance is essential. Consider speaking with a healthcare provider if:
- You experience unexplained weight loss or gain
- Your BMI is below 18.5 or above 30
- You have difficulty losing weight despite diet and exercise
- You have signs of metabolic issues like high blood pressure or high cholesterol
- You have concerns about eating disorders or disordered eating patterns
Your doctor can perform a comprehensive assessment, consider your family history, and help you develop a personalised plan that addresses your unique needs.
Putting It All Together
Understanding your ideal weight isn’t about chasing a number — it’s about finding a weight that supports your health, energy, and quality of life. The charts and formulas we’ve explored are valuable tools, but they’re just one piece of the puzzle.
The most important thing is to listen to your body, build sustainable habits, and work with healthcare professionals who can guide you on your journey. Whether you’re just starting out or you’re looking to refine your approach, remember that every step toward better health is a step worth taking.
