Overweight Calculator
Enter your height and weight to see your BMI, weight category, and how much weight you would need to lose (or gain) to stay within the healthy BMI range.
Your Measurements
Use a stadiometer for height and a calibrated scale for weight.
Your Overweight Assessment
BMI
27.7
Body Mass Index (kg/m²)
Category
Overweight
Healthy weight range
53.5 – 72 kg (117.9 – 158.6 lb)
You are 8 kg (17.7 lb) above the upper healthy BMI limit. This is about 11.2% higher than the recommended maximum weight for your height.
How to Use This Calculator
Measure accurately
Weigh yourself at the same time of day and use a stadiometer for height. Enter values in the same unit system.
Interpret results
Check your BMI category and the amount of weight to lose or gain to reach the healthy range. Use this as a starting point, not a diagnosis.
Plan next steps
Set realistic goals—aim for gradual changes. Consult healthcare professionals before starting major diet or exercise programs.
Formula
BMI = Weight (kg) ÷ Height² (m²)
- Healthy BMI range: 18.5–24.9
- Weight at BMI 18.5 = 18.5 × Height²
- Weight at BMI 24.9 = 24.9 × Height²
- Excess weight = Actual weight − Weight at BMI 24.9 (if positive)
All inputs are converted to metric before calculation. Results are displayed in both kilograms and pounds.
Understanding the Results
BMI is a population-level screening tool. It does not distinguish between fat and muscle, but it provides a quick method for identifying potential risks. Combine it with waist-to-height ratio, body fat percentage, and clinical lab results for a comprehensive evaluation.
If you are overweight, focus on gradual lifestyle changes. Small adjustments to daily movement, nutrition, and sleep can lead to sustainable progress. Always involve healthcare professionals if you have underlying conditions.
Frequently Asked Questions
Is BMI reliable for athletes?
Muscular individuals may have high BMI without excess fat. Combine BMI with body composition tests for accuracy.
How fast should I lose weight?
A gradual loss of 0.5–1 kg (1–2 lb) per week is generally safe. Rapid loss can reduce muscle mass and affect metabolism.
Does age affect BMI recommendations?
BMI thresholds are the same for adults. Older adults may need individualized evaluation considering muscle mass and bone density.
Can this tool replace medical advice?
No. Use it as an educational guide. Always defer to qualified healthcare providers for diagnosis and treatment.
