⚖️ Ideal Weight Calculator
This calculator estimates a healthy weight range based on your height, age, and gender using widely accepted formulas like Devine and Robinson.
What Is an Ideal Weight Calculator
An ideal weight calculator is an online health tool that helps you estimate your healthy body weight range according to your height, gender, and sometimes age. It’s based on medically recognized formulas like BMI (Body Mass Index) and the Devine or Robinson equations. The Ideal Weight Calculator on GetOnlineCalculator.com provides quick, accurate results to help you track fitness goals and maintain a healthy body composition.
Why Knowing Your Ideal Weight Matters
Understanding your ideal weight isn’t just about appearance — it’s about long-term health. Being significantly underweight or overweight can increase the risk of various medical conditions, including diabetes, cardiovascular disease, and joint problems. By knowing your healthy weight range, you can make more informed choices about nutrition, exercise, and lifestyle.
Who Should Use It
Anyone looking to manage or monitor their health can use this calculator — from fitness enthusiasts and nutritionists to people starting a weight loss or gain journey.
How the Ideal Weight Calculator Works
The calculator estimates your ideal body weight using height-based medical formulas developed by experts. It considers gender and, in some cases, age to produce a more tailored result.
Common Formulas Used
Devine Formula
For men: 50 + 2.3 × (height in inches – 60)
For women: 45.5 + 2.3 × (height in inches – 60)
Robinson Formula
For men: 52 + 1.9 × (height in inches – 60)
For women: 49 + 1.7 × (height in inches – 60)
Hamwi Formula
For men: 48.0 + 2.7 × (height in inches – 60)
For women: 45.5 + 2.2 × (height in inches – 60)
The calculator averages results from these formulas to provide a healthy range rather than a single number.
Example Calculation
Let’s say your height is 170 cm (5 ft 7 in):
Converted to inches = 67 in
Using the Devine formula for men:
50 + 2.3 × (67 – 60) = 66.1 kg
For women: 45.5 + 2.3 × (67 – 60) = 61.6 kg
The ideal weight range is around 61–67 kg for this height.
Factors That Influence Ideal Weight
Gender
Men usually have higher muscle mass, leading to higher ideal weight ranges than women of the same height.
Height
Taller individuals naturally have higher healthy weight ranges.
Body Composition
Muscle weighs more than fat, so athletic individuals may weigh more even if they’re within a healthy range.
Age
Metabolism slows with age, which can affect ideal weight distribution.
Bone Structure
People with larger frames or higher bone density may weigh more without being unhealthy.

Ideal Weight vs Body Mass Index (BMI)
Both are related but not the same. BMI calculates body fat based on weight and height, while ideal weight estimates the healthiest range for your frame. The two can complement each other for a more complete understanding of your health.
BMI Formula
BMI = weight (kg) ÷ height² (m²)
A healthy BMI is typically between 18.5 and 24.9.
Ideal Weight Range Example
For someone 170 cm tall, a BMI of 18.5 to 24.9 corresponds to a weight range of 53–72 kg.
Tips to Maintain Ideal Weight
Eat balanced meals rich in proteins, fiber, and healthy fats.
Stay active with a mix of cardio and strength exercises.
Drink sufficient water daily.
Monitor progress regularly using both a scale and body composition tools.
Get enough sleep and manage stress effectively.
Why Ideal Weight Is Different for Everyone
Two people of the same height may have different ideal weights depending on muscle mass, metabolism, and genetics. The calculator provides a general range, not an absolute target. For athletes, body fat percentage or waist-to-hip ratio may be more accurate health indicators.
Health Risks of Being Over or Under Ideal Weight
Being Overweight
Increases risk of heart disease, type 2 diabetes, high blood pressure, and joint pain.
Being Underweight
May cause nutrient deficiencies, low energy, and weakened immunity.
Maintaining a healthy weight helps reduce these risks and promotes long-term wellness.
