Ideal Weight Calculator – Quick, Free, and Easy to Use
The Ideal Weight Calculator on Addition.site lets you find an approximate healthy weight range based on your height and gender. All for free. It’s built on the classic Devine formula, which is widely used in medical settings to estimate a “normal” weight for a given height. While the result is a useful reference point, it’s not a medical diagnosis – it doesn’t take muscle mass, bone density, or body composition into account. Use it as a starting point for healthy living, not a definitive target.
How to Use the Calculator
- Enter your height in centimeters (e.g., 170 cm). The field defaults to 170 cm for convenience.
- Select your gender from the drop‑down menu (male or female). The formula uses the same weight‑per‑centimeter multiplier for both genders, but the base weight differs (50 kg for males, 45.5 kg for females).
- Click “calculate” to see your ideal weight. The result appears in the read‑only box as “XX.X kg”.
- Copy the result by simply clicking the value; a “Copied!” message will appear.
- Share on X (formerly Twitter) with the “𝕏” button if you want to post your number on social media.
What the Numbers Mean
- The calculator uses the Devine Formula:
Base weight + (height – 152.4 cm) × 0.9 kg per cm.
152.4 cm equals 5 ft, the reference height in the original formula. - The output is an average weight that would be considered “normal” for someone of that height.
- It’s best used as a guideline for healthy weight management rather than a strict target.
When and Why to Use It
- Weight Management – Get a quick benchmark before starting a diet or exercise plan.
- Health Planning – Doctors often use similar calculations to determine medication dosages or assess risk.
- Athletes & Fitness Enthusiasts – Compare your current weight to the ideal range to gauge body composition changes over time.
- Curiosity & Self‑Awareness – Simply to understand how height and gender influence expected body weight.
Important Caveats
- The formula ignores muscle mass, bone density, and body fat percentage. Athletes or very muscular individuals may weigh more than the “ideal” value and still be healthy.
- It’s not a substitute for professional medical advice. If you have health concerns, consult a healthcare provider.
- The calculator is free and no sign‑up required.
Healthy Living Tips (Beyond the Calculator)
- Eat a balanced diet rich in fruits, vegetables, lean proteins, and whole grains.
- Engage in regular physical activity—mix cardio, strength training, and flexibility work.
- Get 7–9 hours of quality sleep per night to support recovery and hormone balance.
- Stay hydrated and manage stress; both impact body composition and overall well‑being.
Use the Ideal Weight Calculator as a quick, user‑friendly tool to explore your health goals. Combine the result with healthy lifestyle habits, and you’ll be on the path to feeling stronger, energized, and confident in your own body.
