Formula and Logic
This calculator uses the Devine formula, a common method in health and fitness for estimating ideal body weight. For men, the formula is: 50 kg + 0.9 kg per cm over 152 cm. For women, it is: 45.5 kg + 0.9 kg per cm over 152 cm. A body frame multiplier is applied: 0.9 for small frames, 1.0 for medium, and 1.1 for large frames to account for skeletal variation.

Frequently Asked Questions
Is this calculator accurate for everyone?
No, it is a general estimate. Individual factors like genetics, muscle mass, and medical conditions can affect your ideal weight. Use it as a starting point, not a definitive target.
Can I use this for weight loss or muscle gain plans?
Yes, but combine it with a balanced diet and exercise. For muscle gain, focus on strength training and protein intake; for weight loss, aim for a sustainable calorie deficit.
What if my height is in feet and inches?
Convert feet and inches to total inches first (e.g., 5'8" is 68 inches), then enter the value in the inches option. Alternatively, use an online converter for centimeters.
