Your Estimated Ideal Weight
Wondering what your ideal weight should be? Our Ideal Weight Calculator provides a quick estimate based on your height and sex using commonly used ideal body weight formulas. It can help you set realistic health and fitness goals and understand how your current weight compares with a general reference point.
Remember: There is no single perfect weight for everyone. Muscle mass, body composition, age, genetics, lifestyle, and overall health can all influence what a healthy weight looks like.

→ Read the Ideal Weight Calculator GuideWhat Is Ideal Weight?
Ideal weight is an estimated body weight that may be considered appropriate for a person’s height. It is usually calculated using mathematical formulas that take height and sex into account.
The concept of ideal body weight is useful as a general reference, but it should not be considered an exact measurement of health. Two people with the same height can have very different amounts of muscle, fat, bone mass, and body composition.
That’s why your calculator result should be viewed as a starting point rather than a strict weight target.
How Does the Ideal Weight Calculator Work?
The calculator uses established mathematical formulas to estimate ideal body weight. One of the most commonly referenced formulas is the Devine formula.
Different ideal-weight formulas can produce slightly different results. This is normal and is one reason why an ideal weight estimate should not be interpreted as a precise medical target.
Why Does Height Matter for Ideal Weight?
Height is one of the most important factors used in ideal-weight calculations because body size generally increases as height increases.
For example, a healthy weight for someone who is 160 cm tall will generally be different from the healthy weight range for someone who is 190 cm tall.
This is why simply comparing your weight with another person’s weight does not tell you whether your weight is appropriate for your body.
Ideal Weight Examples by Height
Here are approximate examples using the Devine ideal body weight formula. They are provided for educational purposes and should not be treated as personalized medical recommendations.
| Height | Estimated Male IBW | Estimated Female IBW |
|---|---|---|
| 5’0″ (152 cm) | 50.0 kg | 45.5 kg |
| 5’2″ (157 cm) | 54.6 kg | 50.1 kg |
| 5’4″ (163 cm) | 59.2 kg | 54.7 kg |
| 5’6″ (168 cm) | 63.8 kg | 59.3 kg |
| 5’8″ (173 cm) | 68.4 kg | 63.9 kg |
| 5’10” (178 cm) | 73.0 kg | 68.5 kg |
| 6’0″ (183 cm) | 77.6 kg | 73.1 kg |
Ideal Weight vs BMI
Ideal weight and BMI are not the same thing. BMI, or Body Mass Index, calculates a value using your height and weight and places the result into standard BMI categories.
An ideal-weight calculator instead estimates a reference body weight using a specific mathematical formula.
For a better understanding of your weight, it can be useful to look at several measurements instead of relying on one number.
Check Your BMI Too
Your BMI can provide another useful reference when evaluating your current weight relative to your height.

Body weight alone cannot tell you how much of your weight comes from fat or lean tissue. Someone who regularly strength trains may weigh more because they have more muscle mass.
Body fat percentage can therefore provide additional information about body composition that an ideal-weight formula cannot capture.

Our Body Fat Calculator estimates body fat percentage using the U.S. Navy circumference method.

Yes. An ideal-weight estimate can be useful when establishing a long-term weight-management goal. However, you should avoid treating the calculated number as a deadline or trying to reach it as quickly as possible.
Sustainable weight loss usually involves a reasonable calorie deficit, adequate nutrition, regular physical activity, sufficient sleep, and consistent habits.
Can Ideal Weight Help With Weight Gain?
If your goal is to gain weight, an ideal-weight estimate can give you a general reference point. However, healthy weight gain should focus on building useful body mass rather than simply increasing scale weight.
Adequate calories, sufficient protein, resistance training, and recovery can all play an important role in supporting muscle growth.
Limitations of Ideal Weight Calculators
Ideal-weight formulas are useful reference tools, but they have important limitations.
- They do not directly measure body fat percentage.
- They cannot accurately account for muscle mass.
- Bone structure can vary significantly between individuals.
- Different formulas can produce different results.
- Age, genetics, lifestyle, and health conditions may influence a person’s appropriate weight.
- They should not replace professional health assessment.

What is my ideal weight?
Your estimated ideal weight depends mainly on your height, sex, and the formula used. Use the calculator above to get an estimate based on commonly used ideal body weight equations.
Is ideal weight the same as healthy weight?
Not necessarily. Ideal weight is a mathematical estimate, while healthy weight depends on body composition, muscle mass, age, lifestyle, and overall health.
How accurate is an Ideal Weight Calculator?
An ideal-weight calculator can provide a useful general estimate, but it cannot determine the exact healthiest weight for every individual.
Does muscle mass affect ideal weight?
Yes. People with more muscle mass may weigh more than an ideal-weight formula suggests while still having a healthy body composition.
Can I use ideal weight as my weight-loss goal?
You can use it as one reference when setting a long-term goal, but a realistic target should also consider your current health, body composition, lifestyle, and sustainable rate of change.
What should I check besides ideal weight?
BMI, body fat percentage, waist circumference, fitness level, nutrition, and overall health can provide additional context.
