Calculate Your Peso Ideal
Use your height and sex to estimate ideal body weight with multiple clinical formulas plus a healthy BMI range.
What is a “peso ideal” calculator?
A peso ideal calculator is a tool that estimates a healthy target weight based mainly on your height and sex. The phrase “peso ideal” is commonly used in Spanish-speaking countries and means “ideal weight.” Most calculators do not produce a single “perfect” number; they give a practical range and formula-based estimates.
This matters because healthy body weight is linked to blood pressure, glucose control, cardiovascular risk, energy levels, and long-term mobility. Still, ideal weight is only one part of overall health. Sleep, fitness, nutrition quality, stress management, and muscle mass all play major roles.
How this calculator works
The calculator above combines two approaches:
- Ideal Body Weight formulas: Devine, Robinson, Miller, and Hamwi.
- Healthy BMI range: a weight range that corresponds to BMI 18.5 to 24.9 for your height.
By showing several formula outputs, you get a more realistic estimate than relying on one method alone. The “average formula estimate” can be useful as a midpoint, while the BMI range gives broader context.
The formulas used
- Devine: common in clinical settings and medication dosing discussions.
- Robinson: adjusted coefficients that can produce slightly lower estimates.
- Miller: another alternative with different scaling above 5 feet.
- Hamwi: older but still widely referenced.
All of these start from a baseline at 5 feet and add weight per inch above that height. Because bodies vary, it is normal for formula results to differ by a few kilograms.
How to interpret your results
1) Use the range, not a single number
If your formula average is 67.8 kg and your BMI range is 56.5 to 76.0 kg, the most practical takeaway is that your healthy target can sit within that broader range depending on your frame and muscle mass.
2) Consider body composition
A person with higher lean mass (more muscle) may be healthy at a higher body weight than BMI alone suggests. Athletes and people doing resistance training often fall into this category.
3) Track trends over time
One measurement is less useful than a trend. Re-check every few weeks and focus on sustainable progress (for example, 0.25 to 0.75 kg per week when trying to lose weight).
Healthy strategies to reach your ideal weight
- Prioritize protein and fiber: they improve satiety and help preserve muscle.
- Create a modest calorie deficit: avoid aggressive dieting that is hard to maintain.
- Strength train 2–4 times per week: supports metabolic health and body composition.
- Walk daily: simple, low-impact movement adds up quickly.
- Sleep 7–9 hours: poor sleep increases hunger and cravings.
- Monitor waist circumference: abdominal fat risk is important, even at “normal” weight.
Important limitations
No calculator can fully account for genetics, body frame, ethnicity, hormonal status, medication effects, or training history. Pregnant individuals, adolescents, older adults with sarcopenia, and people with certain medical conditions may need individualized guidance.
If you have diabetes, thyroid disorders, cardiovascular disease, kidney disease, or recent major weight changes, consult a physician or registered dietitian for a personalized plan.
Final takeaway
A peso ideal calculator is best used as a starting point, not a final verdict. Use the numbers to set a realistic direction, then pair them with healthy habits, regular follow-up, and professional advice when needed. Sustainable routines outperform short-term extremes every time.
