Ideal Weight Calculator

How the Ideal Weight Calculator works

Shows ideal-weight estimates from several published formulae (Devine, Robinson, Miller) so you can see the spread instead of one magic number.

Formula / method. Devine (men): 50 + 2.3 kg per inch over 5 ft. Robinson and Miller use different intercepts and slopes; women have their own coefficients.

When to use it. Use it as a range, next to BMI. Frame size and muscle mass are not in these formulae.

How to run a comparison

1. Open Ideal Weight Calculator from Home search, the Health & Vitality hub, or this URL.
2. Copy amounts, rates or dates from a document you already have — not a round marketing figure.
3. Read the headline result and any breakdown (schedule, slabs, or intermediate rows).
4. Change one input at a time so you can see what actually moves the answer.
5. Cross-check with a related calculator below, then confirm statutory rates before you act.

Nothing you type is uploaded for server-side processing. Save or screenshot an output if you need it later; we do not keep a server-side history.

Notes and assumptions

Adult formulae. Not for children. Not a prescription.

Results are estimates for education and planning only. They are not financial, tax, medical, or legal advice. Slabs, scheme rates and product terms change; verify against official notifications or a qualified professional before acting.
