How to use it
- Enter your height in inches.
- Select your gender (0 for male, 1 for female).
- Click the calculate button to see your ideal weight in kilograms.
What it does – The Ideal Body Weight Calculator takes your height in inches and gender (0 = male, 1 = female) and applies the Devine formula to give a single number in kilograms. Why it matters – Knowing your ideal weight helps you set realistic fitness goals, gauge nutritional needs, and track progress without guessing. It’s a reference point, not a medical prescription. How to read it – The result is the weight your body is expected to carry at a healthy frame. Compare it to your current weight: if you’re above, you may aim to lose; if below, you might focus on gaining muscle. Example – A 68‑inch male (0) gets 50 kg + 2.3 kg × 8 = 68.4 kg. A 64‑inch female (1) gets 45.5 kg + 2.3 kg × 4 = 55.7 kg. Use the calculator before starting a new training program to set a baseline and keep your plan aligned with a healthy target.
Pro tips
- Round the result to the nearest 0.5 kg for practical meal planning.
- If your height is exactly 5 ft, the formula adds zero inches – the base weight applies.
- Enter gender as 0 for male, 1 for female; swapping will give the wrong value.
- Use the calculator as a reference, not a strict limit; individual body composition varies.
Real-life examples

Case study
Jake, a 30‑year‑old male, was 70 in tall and weighed 85 kg. After entering his height and gender into the calculator, he saw an ideal weight of 71 kg. He adjusted his diet and training, and three months later his weight was 72 kg, matching the target range.
