Frequently Asked Questions
Ideal weight is an estimate of the weight range that is associated with optimal health for a person of a given height. It’s calculated using various scientific formulas developed by medical researchers over decades of study.
The Devine formula (1974) is widely used in medical settings and pharmaceutical dosing. However, different formulas may be more appropriate for different populations. BMI-based ranges from WHO provide broader healthy weight guidelines that account for individual variation.
These formulas provide general estimates and should not replace professional medical advice. Individual factors like muscle mass, bone density, overall health, and body composition should be considered by healthcare professionals for personalized recommendations.
Frame size refers to bone structure and overall body build. People with larger frames may have a higher ideal weight range, while those with smaller frames may have a lower range. This adjustment helps account for individual skeletal differences.

Welcome to our Ideal Weight Calculator, the easiest way to discover your healthy weight range based on your height, age, and gender.

Whether you’re planning to lose fat, gain muscle, or simply stay healthy, this calculator gives you a clear target range to work toward.
How the Ideal Weight Calculator Works
The Ideal Weight Calculator uses scientifically proven formulas to estimate your healthiest weight range. The most common methods include:
- BMI (Body Mass Index): Compares your weight to height.
- Devine Formula: Popular for calculating ideal body weight in medical settings.
- Robinson, Miller, and Hamwi Formulas: Adjust weight ranges slightly depending on height and gender.
By combining these approaches, the calculator provides a realistic weight range rather than a single number. This is helpful because every body type is different.

Ideal Weight Calculator vs. BMI
Although the Ideal Weight Calculator often uses BMI as a base, there’s a key difference:
- BMI Calculator → Focuses on weight relative to height only.
- Ideal Weight Calculator → Provides a more personalized weight range that accounts for gender and sometimes frame size.

Ideal Weight Ranges for Men and Women
Here are some general examples of healthy weight ranges for adults:
- A 170 cm (5’7”) male → Ideal weight is usually between 63–72 kg.
- A 160 cm (5’3”) female → Ideal weight is usually between 50–60 kg.
Keep in mind that athletes and people with higher muscle mass may weigh more than these ranges while still being very healthy.
FAQ – Ideal Weight Calculator
Is the Ideal Weight Calculator accurate?
Yes, it uses well-researched formulas. However, genetics, muscle mass, and body composition can affect results.
What if I’m outside the “ideal” range?
Don’t panic—think of it as a guideline. Focus on healthy habits rather than a single number.
Can athletes weigh more than the ideal weight?
Absolutely! Since muscle is denser than fat, many athletes weigh more while staying healthy.
