Ideal Weight Based on Height and Age: A Complete Guide to Healthy Body Balance
Understanding your ideal weight is an essential part of maintaining a healthy body and avoiding chronic health issues. Many factors influence your ideal weight, including height, age, gender, body composition, and lifestyle. In this article, we’ll explore different methods for calculating ideal weight, how age and height affect body goals, and practical tips for achieving and maintaining a balanced physique.
Why Knowing Your Ideal Weight Matters
Knowing your ideal weight helps you reduce the risk of heart disease, diabetes, joint problems, and certain cancers. It can also improve your energy levels, mobility, and mental well-being. The ideal weight is not about looking thin—it's about being healthy and comfortable in your body.
Popular Formulas to Calculate Ideal Weight
1. Devine Formula
This is one of the oldest methods used by doctors to estimate ideal weight, especially for drug dosing. The formula is:
- Men: 50 kg + 2.3 kg per inch over 5 feet
- Women: 45.5 kg + 2.3 kg per inch over 5 feet
2. Robinson Formula
A slightly more modern adaptation with smaller increments:
- Men: 52 kg + 1.9 kg per inch over 5 feet
- Women: 49 kg + 1.7 kg per inch over 5 feet
3. Miller Formula
Used in some clinical settings, with yet another variant:
- Men: 56.2 kg + 1.41 kg per inch over 5 feet
- Women: 53.1 kg + 1.36 kg per inch over 5 feet
4. BMI-Based Ideal Weight
Instead of using one-size-fits-all formulas, the Body Mass Index (BMI) approach uses a healthy BMI range (18.5 to 24.9) and multiplies it by your height in meters squared.
Ideal Weight by Height Chart
The following table gives you a rough estimate of healthy weight ranges based on height:
| Height | Ideal Weight Range (kg) |
|---|---|
| 150 cm | 45 - 56 |
| 160 cm | 50 - 63 |
| 170 cm | 57 - 72 |
| 180 cm | 65 - 81 |
| 190 cm | 72 - 91 |
How Age Affects Ideal Weight
As you age, your metabolism slows down and muscle mass may decrease. This means that your ideal weight might shift slightly. It’s natural to gain a little weight with age, but maintaining healthy habits helps manage this balance.
Ideal Weight for Children and Teenagers
Ideal weight for children is based on growth charts developed by WHO and CDC. Pediatricians use percentiles based on age and gender. Weight should not be assessed in isolation for kids—it should consider development, nutrition, and activity level.
Gender Differences in Ideal Weight
Men tend to have more muscle mass than women, which impacts their ideal weight. That’s why many formulas calculate different baselines for males and females. Hormonal differences also affect fat distribution.
Body Composition vs. Weight
Two people with the same weight and height can have very different body compositions. Muscle weighs more than fat but is healthier and denser. That’s why measuring fat percentage can be more useful than tracking just weight.

Conclusion
There’s no single “perfect weight” for everyone. Use your height, age, and health goals to find a weight range that works for you. Focus on long-term health, not just numbers. Small, consistent changes to your lifestyle can make a big difference in achieving your ideal weight and living a healthier life.
