Frequently Asked Questions (FAQs)
Q: What does an ideal weight calculator do?
Using proven medical formulas—not trends or fads—an ideal weight calculator figures out a healthy weight range for you based on height and sex.
Q: How precise is this calculator?
It uses peer-reviewed, clinically validated formulas. It’s not diagnostic, but offers a science-based starting point for healthy goal-setting.

Muscle increases weight. Use this as a baseline, but consult a sports nutritionist for personalized guidance.
Q: Does age affect the outcome?
These formulas are for ages 18–65. Older adults may have different healthy ranges due to muscle loss (sarcopenia).
Q: Is my information safe?
Yes. We never store or share your data. Your browser does all calculations.
Q: Is it okay to use on my phone?
Yes! Works perfectly on iPhone and Android—great for home or gym use.
Q: Who can use this tool?
Good for health improvement, but not for medical diagnosis. Always consult a doctor for personal health advice.
