Ideal Weight Calculator

Purpose: Find your ideal body weight from height and sex using established medical formulas, plus the healthy BMI weight range.

Ideal Weight Calculator

The Ideal Weight Calculator estimates a healthy target weight for your height and sex using established clinical formulas such as Devine and Robinson.

Formulas, not a single truth

There is no one "ideal" weight, so the calculator reports several respected estimates - Devine, Robinson, Miller, and Hamwi - which is why you see a range rather than a single number. These formulas were originally developed for medical dosing and give a useful healthy-weight guideline based mainly on height.

How to use the range

Treat the output as a target band, not a strict goal. Frame size, muscle mass, and body composition all shift what is healthy for you. Combine it with your BMI and body-fat readings for a fuller picture, and consult a healthcare professional before setting a serious weight target.

Frequently Asked Questions

Why does it show several ideal weights?

Different clinical formulas (Devine, Robinson, Miller, Hamwi) give slightly different results, so a range is more honest than a single number.

Are these formulas based on height alone?

Largely yes - they estimate healthy weight primarily from height and sex, which is why they are guidelines rather than precise targets.

Does muscle affect my ideal weight?

Yes. Muscular people may healthily weigh more than the formulas suggest, so consider body composition alongside the estimate.

Should I aim for the exact number?

No. Use it as a target band and factor in your frame, fitness, and a professional's advice rather than chasing an exact figure.
