Ideal Weight Calculator
Enter your height and sex to see an estimated ideal weight range, calculated using several well-known formulas (like Devine and Robinson) side by side — a general reference, not personalized medical advice.
All calculations happen on your device — your health data is never sent to a server.
This result is a general estimate using the widely used Devine formula, and doesn't account for frame size or muscle mass — it's an informational tool only, not a substitute for a doctor's or dietitian's advice.
What this tool does
Estimates a reference weight for a given height and sex using the Devine formula, one of the commonly cited reference equations.
When to use it
- Wanting a general reference point for weight relative to height.
- Setting an approximate target within a health plan.
- Comparing your current weight against a widely used reference.
How to use it
- Choose your sex.
- Enter your height.
- Run the calculation and read the reference weight.
A practical example
Input
A height of 175 cm.
Output
A reference weight in kilograms computed by the Devine formula for that height.
Limitations
- This is a general reference number rather than a personal health target; what weight actually suits you needs assessment by a doctor or dietitian.
- The notion of an "ideal weight" is itself contested: the Devine formula was originally devised for calculating drug dosages rather than assessing individual health, and it accounts for neither build, muscle mass nor age.
- A healthy weight is a wide range rather than a single number, and falling outside the formula does not indicate a problem.
- It is not suitable for children, adolescents or pregnant people.
Privacy and processing
Your height and sex are used for the calculation on your device only, and are neither recorded nor transmitted.
Technical notes
- The Devine formula uses height and sex only — which is precisely its limit: it has no input for build or body composition.
