Depth resolution: How do you scientifically determine your ideal weight?
Ideal Body Weight, IBW is not just a number, but an important indicator of whether the body is optimal. The medical community has developed formulas to estimate this value, which are designed to provide a scientific basis for drug dosage calculations, health assessments and fitness targeting.
1. Why are there so many different formulas?
Each formula has its own historical background and application:
- Devine formula (1974): The standard formula that was initially used to estimate the rate of drug clearance is now the most widely used.
- Robinson formula (1983): The Devine formula has been fine-tuned to provide results that are more consistent with the statistical average.
- Miller formula (1983): It's also Devine's variant, but it's more accurate in certain heights.
- Hamwi Formula (1964): Rapid estimation methods commonly used by nutritionists.
2. Impact of bone frame size on desired body weight
This tool introduces a bone structure coefficient. People with the same height, large skeletons have higher bone density and muscle potential, so their ideal weight is usually higher than those with small skeletons. About 10%. This is an important dimension that BMI indices often ignore.
3. Desired body weight range vs. Health weight range
The ideal weight is a “point” and the healthy weight is a “area”. According to the World Health Organization (WHO), BMI is at 18.5 to 23.9 Both are covered by health. For a 175cm tall adult, this means 57kg to 73kg It's all reasonable. As long as your body weight is in this compartment and your lipid ratio is normal, it is not necessary to over-sought the exact values calculated in the formula.
4. Misdirection for desired weight
Muscles vs. fat: The ideal weight formula does not distinguish muscle from fat. If you are a fitness lover with a high muscle content, your weight may exceed the calculated “ideal value”, but this does not mean that you are not healthy.

Note: The data provided in this tool are estimates based on statistical models. The definition of desirable weight varies for pregnant women, professional athletes, older persons or persons with specific illnesses. If there is a doubt, consult a professional doctor or a nutritionist.
