Formula Used

Ideal Weight = (Height - 100) - (Height - 150) / F + G

Where:

Height = Height in centimeters
F = Frame factor (4 for small frame, 2 for medium frame, 0 for large frame)
G = Gender adjustment (10 for males, 0 for females)
Excess Weight = Current Weight - Ideal Weight
Excess Weight Percentage = (Excess Weight / Ideal Weight) × 100

Example Calculation

Real-World Scenario:

A 35-year-old male with a height of 175 cm, current weight of 85 kg, and medium body frame size wants to determine his excess weight.

Given:

Height = 175 cm
Current Weight = 85 kg
Gender = Male
Age = 35 years
Frame Size = Medium

Calculation:

Ideal Weight = (175 - 100) - (175 - 150) / 2 + 10

Ideal Weight = 75 - 25 / 2 + 10

Ideal Weight = 75 - 12.5 + 10 = 72.5 kg

Excess Weight = 85 - 72.5 = 12.5 kg

Excess Weight Percentage = (12.5 / 72.5) × 100 = 17.24%

Result: This person has 12.5 kg of excess weight, which is 17.24% above their ideal weight.

Common Mistakes & Tips

Many people incorrectly estimate their body frame size. To determine your frame size accurately, measure your wrist circumference: for men, less than 6.5 inches (16.5 cm) indicates a small frame, 6.5-7.5 inches (16.5-19 cm) indicates a medium frame, and more than 7.5 inches (19 cm) indicates a large frame. For women, the measurements are less than 6 inches (15.2 cm) for small, 6-6.5 inches (15.2-16.5 cm) for medium, and more than 6.5 inches (16.5 cm) for large.

While excess weight calculation is useful, it doesn't account for body composition. Muscle weighs more than fat, so someone with high muscle mass may weigh more but still be healthy. Consider using this calculator alongside other metrics like body fat percentage, waist-to-hip ratio, and overall health indicators for a more complete picture of your health status.

After calculating excess weight, some people set aggressive weight loss goals that are difficult to maintain. Healthy weight loss is typically 0.5-1 kg (1-2 pounds) per week. Rapid weight loss often leads to muscle loss and can be unsustainable. Use your excess weight calculation to set realistic, long-term goals and focus on gradual, sustainable lifestyle changes rather than quick fixes.

Frequently Asked Questions

BMI (Body Mass Index) only considers height and weight, while this excess weight calculator takes into account additional factors like gender, age, and body frame size. This provides a more personalized assessment of your ideal weight and how much excess weight you might be carrying. BMI can be misleading for people with significant muscle mass or different body frame sizes, whereas this calculator offers a more nuanced evaluation.

Not necessarily. The health impact of excess weight depends on various factors including body composition, fitness level, and overall health. Some people with slightly higher weight may be metabolically healthy if they maintain an active lifestyle and have good muscle mass. However, significant excess weight (typically more than 20% above ideal weight) is associated with increased health risks including cardiovascular disease, diabetes, and joint problems. It's best to consult with a healthcare professional for personalized advice.

For most people, calculating excess weight every 1-2 months is sufficient when actively trying to manage weight. More frequent calculations may lead to unnecessary focus on daily fluctuations, which can be affected by water retention, hormonal changes, and other temporary factors. It's more important to focus on long-term trends rather than daily variations. Remember that healthy weight management is a gradual process, and consistent lifestyle changes are more effective than short-term diets.
