Ideal Weight Calculator
Use this tool to find the ideal weight range for your height and gender. It’s not about chasing a “perfect” number, but understanding a healthy weight target that supports your well-being and lifestyle.
What Is an Ideal Weight?
Ideal weight is an estimate of how much a person should weigh for their height, based on formulas created by health experts. It does not account for body fat or muscle, but it gives a rough guide to where your weight should fall to reduce health risks.
How Ideal Weight Is Calculated
This calculator uses proven methods like:
- Devine formula
- Robinson formula
- Miller formula
- Hamwi method
- BMI range-based estimates
These methods use your height and gender to suggest a target weight. Each one gives a slightly different number, so it’s best to view them as a guide — not a fixed rule.
Example (Female, 5’5” / 165 cm):
Formula | Ideal Weight |
---|---|
Devine | 125 lbs (56.7 kg) |
Miller | 122 lbs (55.3 kg) |
Robinson | 121 lbs (54.9 kg) |
Hamwi | 124 lbs (56.2 kg) |
BMI and Healthy Weight Range
Your BMI (Body Mass Index) also plays a role in determining your ideal weight range. A healthy BMI falls between 18.5 and 24.9.
Height (cm) | Healthy Weight Range (kg) |
---|---|
160 | 47 – 64 |
165 | 50 – 68 |
170 | 53 – 72 |
175 | 56 – 77 |
🔎 The calculator can also estimate your healthy weight range based on this BMI scale.
What Affects Ideal Weight?
Several things affect your “normal” weight:
- Height – Taller people naturally weigh more.
- Gender – Men often weigh more due to higher muscle mass.
- Body Frame – People with larger bone structure may weigh more.
- Age – As you get older, muscle may decrease and fat may increase.
- Fitness level – Athletes may weigh more but still be healthy.
🧠 That’s why ideal weight is just a guide. Muscle weighs more than fat, and two people at the same height can look very different.
Why It Matters
Staying in a healthy weight range helps lower the risk of:
- Heart disease
- Type 2 diabetes
- High blood pressure
- Joint pain
- Sleep issues
It also improves energy, mobility, and quality of life over time.
Not One Size Fits All
Don’t stress about hitting an exact number. Ideal weight isn’t a pass/fail score. You can be outside the “ideal” range and still be fit, strong, and healthy.
Instead of focusing only on the scale, look at:
- Body composition (fat vs. muscle)
- Waist size
- Energy levels
- Daily habits
Your health is more than a number.

Final Note
Ideal weight is a helpful reference — not a fixed target. Don’t let numbers define your progress or self-worth. Aim for strength, balance, and habits that support your health.
