Potton ideal weight calculator
How to use this page
- Fill in the fields in the form above — the result recomputes at once, with no page reload.
- Under the result you will find the interpretation scale, if the calculator has one: it says which range your value fell into.
- The formula we use is shown lower on this page — you can check the arithmetic yourself.
- To compute the same for another game or variant, change it in the select field — prices and pools update automatically.
What this page does not do: It does not point to numbers to play and does not predict a draw — every draw is independent of the previous ones.

Formula
men: H − 100 − (H − 100) / 20 women: H − 100 − (H − 100) / 10 The Potton formula belongs to the family of simple historical ideal-weight formulas, next to Broca and Lorentz. All start from the same point — height in centimetres minus 100 — and differ in the correction. Potton subtracts a fixed fraction of that value: one twentieth for men and one tenth for women. For a man of 180 cm: 80 − 80 / 20 = 76 kg; for a woman of the same height: 80 − 80 / 10 = 72 kg.
Compared with Lorentz, Potton's correction is milder and proportional to height rather than to the excess above 150 cm. For very tall people Potton therefore gives a higher ideal weight than Lorentz, for short people a similar one. None of these formulas knows age, bone structure, muscle share or fitness, so differences of a few kilograms between them carry no practical meaning.
Treat the result as a reference point to compare with your actual body weight, not as a target. Modern nutritional assessment relies on BMI, waist circumference (WHtR) and body composition; when in doubt about the interpretation, ask a doctor or dietitian.
Frequently asked questions
What is the Potton formula?
For men: height − 100 − (height − 100) / 20. For women: height − 100 − (height − 100) / 10. For 180 cm this gives 76 kg and 72 kg.
How does Potton differ from Lorentz?
Lorentz subtracts part of the height excess above 150 cm (divisor 4 for men, 2.5 for women), Potton part of the whole „height minus 100”. For 180 cm Lorentz gives 72.5 kg and 68 kg, Potton 76 kg and 72 kg.
Does the result say how much I should weigh?
No. It is an indicative value from a historical formula that ignores age and body build. Body weight is a topic for a doctor or dietitian.
