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):

FormulaIdeal Weight
Devine125 lbs (56.7 kg)
Miller122 lbs (55.3 kg)
Robinson121 lbs (54.9 kg)
Hamwi124 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)
16047 – 64
16550 – 68
17053 – 72
17556 – 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.
