How to find out ideal weight: calculation method, required inputs, worked check, limitations and a link to Ideal Weight Calculator. Reviewed 25 September 2026.

For “How to find out ideal weight”, the linked Ideal Weight Calculator is relevant because See estimated ideal weight ranges from several classic formulas based on height and sex.
What this specific question is asking
Before running Ideal Weight Calculator, write down what sex and height (cm) mean for your case — including each unit and time period. The calculator multiplies whatever it is given; the setup decides whether the answer is usable.
A fast validation: take the worked example (As a worked reference for “How to find out ideal weight”, Worked…), swap in your own sex, and confirm the result shifts in the direction the relationship predicts. If it moves the wrong way, recheck the units before the math.
Inputs to verify
- Verify sex before calculation; if this value uses a different unit, period or definition, convert or restate it first.
- Verify height (cm) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Step-by-step check
- Select your sex.
- Enter your height in centimetres for the formulas.
- Press Calculate to see several ideal-weight estimates.
- Read them as a range, not a single fixed goal.
Worked example and sanity check
As a worked reference for “How to find out ideal weight”, Worked example For a 175 cm male (Devine formula): 50 + 2.3 × ((175−152.4)/2.54) = 70.5 kg as a rough reference, not a target.
Interpreting the result
Interpretation starts with magnitude. The worked example landed at 70; compare yours before trusting the decimals. If the two disagree wildly, the setup — usually sex's unit or period — is the suspect. Treat the number as a screening estimate for orientation, not a diagnosis or a personalised prescription; individual measurement error and physiology dominate any formula's precision.
