Ideal Weight Calculator — Healthy Weight for Your Height

What is a Ideal Weight?

This ideal weight calculator tells you the healthy weight for your height, gender, and body frame — instantly, for free. It uses the Devine medical formula (1974), the most widely used clinical standard for ideal body weight, originally developed for pharmaceutical dosing. If you have ever asked "what should I weigh?" or searched for a perfect weight calculator, this tool gives you a science-based answer rather than a generic chart. Unlike BMI, this optimal weight calculator accounts for body frame size — small, medium, or large — because two people of the same height can naturally carry different healthy weights based on bone structure. The result shows your ideal weight as a range, not a single number, and tells you exactly how many kg to lose or gain to reach it. **Ideal Weight by Height Reference Table (average frame):** Height 5'0" (152 cm): 45–55 kg | Height 5'4" (163 cm): 52–62 kg | Height 5'6" (168 cm): 56–66 kg | Height 5'8" (173 cm): 60–70 kg | Height 5'10" (178 cm): 64–74 kg | Height 6'0" (183 cm): 68–78 kg | Height 6'2" (188 cm): 72–83 kg These are approximate ranges for a medium frame. Small frames target the lower end; large frames target the upper end. Use this desired weight calculator to get your personalised result based on your exact height and frame.

How to Use This Calculator

Enter your height in centimeters. Select your gender. Then select your body frame size — to determine your frame, wrap your thumb and middle finger around your wrist: if they overlap you have a small frame, if they just touch you have a medium frame, and if there is a gap you have a large frame. Click Calculate to see your ideal weight range, and exactly how many kg you need to lose or gain. This healthy weight for height calculator also shows the BMI-based comparison range for reference.

💡 Pro Tips

• ✓Ideal weight is a range, not a single number — any weight within your healthy range is equally good. The table above shows typical ranges by height.
• ✓Muscle weighs more than fat — strength athletes may sit above their "ideal" weight while being very healthy. The desired weight calculator reflects this through frame size.
• ✓Never aim for a weight below the minimum of your healthy range — being underweight carries serious health risks including bone density loss and hormonal disruption.
• ✓Use this optimal weight calculator as a long-term target, not a short-term obsession — sustainable lifestyle changes matter far more than hitting an exact number.
• ✓Combine ideal weight tracking with body fat percentage measurement for a complete health picture — two people at the same weight can have very different body compositions.
