What BMI measures

BMI is weight relative to height. It’s a screening metric, not a direct measure of body fat or health.

Best next step

If you’re planning nutrition, use TDEE for maintenance calories, then choose a moderate deficit/surplus and adjust based on trends.

BMI is a height-adjusted weight screening metric. Your BMI is 24.5 (Normal). For goal calories and nutrition planning, estimate maintenance with the TDEE Calculator.

How this BMI calculator works

BMI (Body Mass Index) compares your weight to your height. It’s widely used as a screening metric to categorize underweight, normal weight, overweight, and obesity.

If your goal is nutrition planning, use BMI as context and estimate maintenance calories with the TDEE Calculator, then adjust gradually.

Formula

BMI = weight (kg) ÷ height (m)²

BMI categories for adults are typically: under 18.5 (underweight), 18.5–24.9 (normal), 25–29.9 (overweight), 30+ (obesity).

Example

Example: 175 cm and 75 kg.

Height = 1.75 m

BMI = 75 ÷ (1.75 × 1.75) ≈ 24.5

For body composition context beyond BMI, you can also use the Body Fat Calculator.
