Using the Ideal Weight Calculator
What the calculator does
Start here if you need to estimate an ideal weight range reference from sex and height and compare the outcome quickly.
It works best as a reference estimate you can compare against other inputs, habits, or professional guidance.
Formula and calculation explanation
Enter Sex and Height. Those values let the page estimate an ideal weight range reference from sex and height.
This calculator uses a Devine-style reference formula. It starts from a baseline weight at five feet tall and then adds weight for each inch above that height.
Male reference
\[Ideal\ Weight = 50 + 2.3 \times (Inches - 60)\]
The result is first calculated in kilograms and then shown in pounds.
Female reference
\[Ideal\ Weight = 45.5 + 2.3 \times (Inches - 60)\]
Only inches above five feet add to the baseline.
Real-world examples
- Real-world setup: try sex Female and height 165 when you want to move from a rough question to a concrete scenario.
- What-if example: rerun the same setup with a different height to compare how much the headline answer moves.
Step-by-step walkthrough
- Enter Sex and Height.
- Choose the correct mode, category, or unit options before you calculate.
- Click Calculate Ideal Weight. The calculator applies the method shown above and updates the answer instantly.

Does this replace medical advice or diagnosis?
No. Health calculators are best used for rough planning and screening. They should support, not replace, individualized advice from a qualified professional.
Why might this calculator differ from another tool?
Different tools may use different reference formulas, rounding rules, or category cutoffs. This page uses the method explained in the formula section above.
Common mistakes
- Choosing a unit or mode that does not match the number entered in the field.
- Changing several inputs at once, which makes it harder to see which variable actually moved the result.
Edge cases
- If a required field is left blank or contains an unsupported value, the calculator will not return a useful result until the input is corrected.
Interpretation of results
