To make it easier, we’ve created a simple calculator that can estimate your ideal body weight based on your personal metrics.

What Is Ideal Body Weight and How to Maintain It Naturally
Achieving and maintaining your ideal body weight isn’t just about looking good—it plays a key role in reducing the risk of chronic diseases and improving overall quality of life. In this guide, you’ll learn what “ideal weight” truly means, how to calculate it accurately, and practical ways to sustain it through lifestyle and nutrition.
Understanding Ideal Body Weight
Ideal body weight refers to a healthy weight range based on a person’s height, age, and gender. Staying within this range minimizes your risk of developing conditions such as diabetes, heart disease, infertility, and osteoarthritis. It also supports better hormonal balance and physical performance.
What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is a widely used tool to evaluate whether a person’s weight is appropriate for their height. It is calculated using the formula:
BMI = weight (kg) / height² (m²)
Here’s how BMI values are generally categorized:
- Underweight: Less than 18.5
- Normal weight: 18.5 to 24.9
- Overweight: 25 to 29.9
- Obese: 30 or higher
Although BMI doesn’t measure body fat directly, it provides a helpful general indicator for assessing your health risks based on weight.
Ideal Weight Chart Based on Height
Here’s a quick reference for healthy weight ranges according to height (sourced from the National Institutes of Health):
- 5’0” (60 inches): 97 to 123 lbs
- 5’4” (64 inches): 110 to 140 lbs
- 5’8” (68 inches): 125 to 158 lbs
- 6’0” (72 inches): 140 to 177 lbs
- 6’4” (76 inches): 156 to 197 lbs
These ranges align with a normal BMI of 19–24. Values beyond this range may indicate overweight or obesity and should be addressed with lifestyle changes.
Popular Formulas to Calculate Ideal Body Weight
Various formulas have been developed over time to calculate ideal body weight based on height. Here are some of the most recognized:
1. Hamwi Formula (1964)
- Men: 106 lbs + 6 lbs per inch over 5 feet
- Women: 100 lbs + 5 lbs per inch over 5 feet
2. Devine Formula (1974)
- Men: 50 kg + 2.3 kg per inch over 5 feet
- Women: 45.5 kg + 2.3 kg per inch over 5 feet
3. Robinson Formula (1983)
- Men: 52 kg + 1.9 kg per inch over 5 feet
- Women: 49 kg + 1.7 kg per inch over 5 feet
4. Miller Formula (1983)
- Men: 55.7 kg + 1.39 kg per inch over 5 feet
- Women: 55 kg + 1.33 kg per inch over 5 feet
5. Hammond Formula (2000)
- Men: 48 kg + 1.1 kg per cm over 150 cm
- Women: 45 kg + 0.9 kg per cm over 150 cm
Each of these formulas offers slightly different results, but all aim to establish a baseline for healthy weight based on height and gender.
How to Maintain Your Ideal Body Weight
Achieving your ideal body weight isn’t a one-time event—it’s a continuous process that requires a holistic lifestyle. Here’s how to stay on track:
1. Follow a Balanced Diet
Eating right doesn’t mean skipping meals or avoiding your favorite foods. It’s about making smarter, sustainable choices.
- Choose whole grains like brown rice, oats, and quinoa over refined grains
- Prioritize lean proteins such as fish, poultry, tofu, and legumes
- Include healthy fats from sources like olive oil, nuts, and seeds
- Eat at least 3–4 servings of vegetables and 1–2 servings of fruits daily
- Stay hydrated with plenty of water throughout the day
2. Exercise Consistently
Regular physical activity is key to burning calories and building muscle, both of which are essential for managing weight.
- Aim for at least 150 minutes of moderate exercise per week
- Start with walking, yoga, or light strength training if you’re new to fitness
- Incorporate resistance exercises to boost metabolism and maintain muscle tone
- Stay active throughout the day by taking short walks, using stairs, or stretching
Now that you understand the foundations of achieving and maintaining your ideal body weight, it’s equally important to approach the journey with flexibility, patience, and self-awareness.
4. Avoid Fad Diets and Extreme Calorie Cuts
While it might be tempting to follow quick-fix diet plans that promise fast results, these often backfire in the long run. Sudden calorie restrictions may lead to:
- Nutritional deficiencies
- Muscle loss instead of fat loss
- Slowed metabolism
- Yo-yo weight cycles
Instead, opt for balanced meals that include a variety of nutrients and keep your energy levels stable throughout the day. Sustainable habits always outweigh short-term fixes.
5. Track Progress Mindfully
Rather than obsessing over the scale, use a combination of the following to monitor your progress:
- How your clothes fit
- Energy levels and mood
- Physical strength and stamina
- Routine blood work and medical checkups
Remember, health is not defined by weight alone. True wellness involves physical, mental, and emotional harmony.
6. Consult With Professionals When Needed
A registered dietitian can help you build a meal plan tailored to your needs, while a personal trainer can design an exercise routine that supports your goals and body type. Regular health checkups can also help detect imbalances early and keep you on track.
Limitations Are Not the End Point
It’s worth reiterating that ideal body weight calculators are just starting points. They do not take into account key aspects like:
- Bone density
- Muscle-to-fat ratio
- Genetic predisposition
- Hormonal or metabolic conditions
So while these tools offer helpful insight, they are not diagnostic. Always pair them with personalized guidance and a holistic view of your health.
Final Takeaway
Your ideal body weight is not about chasing perfection—it’s about feeling strong, energized, and confident in your own skin. Use the formulas and charts as reference points, but prioritize overall wellness through balanced nutrition, movement, rest, and regular medical guidance.
Sustainable changes, not shortcuts, are the key to a healthier body and mind.
