Quick start
- Open the Ideal Weight Calculator.
- Enter height in centimeters and choose the formula sex setting because Devine uses different 5-foot base weights.
- Use the first example, "Male 180 cm: 50 + 2.3 x 10.866 in over 5 ft", if you want to see a filled-out calculation before entering your own values.
- Calculate, read the formula line, then copy the result only after the units and assumptions look right.

What this calculator is for
The Ideal Weight Calculator gives a Devine formula reference from height and formula sex, then compares it with the adult healthy BMI range. It is a reference point, not a personal requirement.
Use it when you want to: Estimate a classic Devine formula reference weight. Compare one formula result with the adult healthy BMI range.
What to enter
Good answers start with clean inputs. Before calculating, check the labels, units, and dates so the tool is solving the same problem you actually have.
- Enter height in centimeters and choose the formula sex setting because Devine uses different 5-foot base weights.
- Use the adult healthy BMI range as a wider comparison beside the single Devine formula estimate.
- Remember that frame size, muscle, age, pregnancy, training history, and health history are not included.
Example walkthrough
Try the calculator example: Male 180 cm: 50 + 2.3 x 10.866 in over 5 ft. The example result is 74.99 kg Devine; BMI range 59.94-80.68 kg.
- For a 180 cm male formula example, the calculator starts at 50 kg and adds 2.3 kg for about 10.866 inches above 5 feet.
- That gives 74.99 kg by the Devine formula, while the adult healthy BMI range for 180 cm is about 59.94-80.68 kg.
- For a 165 cm female formula example, the calculator returns 56.91 kg and shows an adult healthy BMI range of about 50.37-67.79 kg.
Formula and steps
In plain language: The Devine estimate starts at 50 kg for the male formula or 45.5 kg for the female formula at 5 feet, then adds 2.3 kg for each inch above 5 feet. This calculator does not subtract below the 5-foot base, and it shows the adult BMI 18.5 to 24.9 range separately. Read the result together with the notes on the page, because health and fitness numbers often need personal context.
Read the formula note when you need to understand where the number came from, especially before comparing results over time.
How to read the answer
Read the main estimate first, then read the note beside it. For health, pregnancy, nutrition, kidney, alcohol, or training decisions with real consequences, use qualified professional guidance.
- Treat the ideal weight number as one historical formula output, not a body judgment.
- The BMI range is usually more useful than a single target because bodies vary and BMI itself is still only a screening reference.
- If your height is at or below 5 feet, this calculator keeps the Devine inches-over-5-feet term at zero instead of subtracting below the base weight.
Common mistakes to avoid
Most bad results come from a small input mistake or from using a rough estimate for a decision it cannot safely answer.
- Do not treat the word ideal as a command.
- Do not use this for children, teen growth, pregnancy, athletic performance, eating-disorder concerns, or medication dosing decisions.
- Do not ignore waist size, body composition, lab results, symptoms, or clinician advice just because one formula gives a tidy number.
What to try next
A related health tool can help check the same topic from another angle, but one number should not replace proper care.
- Use Healthy Weight Calculator for BMI range only.
- Use BMI Calculator to compare current weight with adult BMI categories.
- Use Body Fat Calculator if circumference and body-composition context matters more than a height-only formula.

FAQ in plain language
When should I use the Ideal Weight Calculator?
Use it for simple educational checks, trend tracking, or planning tasks like these: Estimate a classic Devine formula reference weight. Compare one formula result with the adult healthy BMI range. It can help you understand a number, but it cannot explain your whole health situation.
What do the main Ideal Weight Calculator inputs mean?
Enter the body, activity, date, or lab values exactly in the units shown on the page. Height, weight, age, sex, time, and activity level can change health estimates a lot, so treat each label like a rule instead of a suggestion. If you are unsure which option fits, choose the closest honest match and read the result as a rough estimate.
What is the Ideal Weight Calculator doing with my inputs?
In plain language: The Devine estimate starts at 50 kg for the male formula or 45.5 kg for the female formula at 5 feet, then adds 2.3 kg for each inch above 5 feet. This calculator does not subtract below the 5-foot base, and it shows the adult BMI 18.5 to 24.9 range separately. Read the result together with the notes on the page, because health and fitness numbers often need personal context.
How should I read the Ideal Weight Calculator result?
Use the result as a learning number, not a final answer about your body or health. The supporting lines can show categories, ranges, calories, dates, or targets, but those numbers still need context like age, medical history, pregnancy status, training level, and advice from a qualified professional.
Is Devine ideal body weight the same as a healthy weight?
No. Devine gives one historical formula estimate from height and formula sex. The healthy BMI range is a wider adult screening range from height squared. Neither one can see body composition, frame size, pregnancy, age, training history, or medical context.
Why does the calculator show a BMI range too?
A single Devine number can look more exact than it really is. The adult BMI 18.5 to 24.9 range gives a broader comparison for the same height, so you can see that one formula number is not the only possible reference point.
What happens if height is 5 feet or shorter?
This calculator keeps the Devine inches-over-5-feet term at zero. That means the male formula stays at 50 kg and the female formula stays at 45.5 kg at or below 5 feet. Use that as a formula boundary, not as advice for children, very short adults, or medical dosing.
