Quick answer
Yes — by the standard adult chart, a BMI of 25.0 is the lower edge of the 'overweight' band (25.0–29.9). A BMI of 24.9 falls into the 'healthy' range, so you're right at the boundary.
BMI 25.0 = lower edge of 'overweight' (25.0–29.9)

How it works
BMI is a screening tool that estimates whether your weight is in a healthy range relative to your height. It doesn't measure body fat directly.
Formula
BMI = weight (kg) ÷ height (m)²
Common mistakes
- Mixing units — entering height in cm but weight in pounds.
- Treating BMI as a diagnosis. It's a screening signal, not a verdict.
- Using adult ranges for children or teens.
- Ignoring muscle mass — athletes often score 'overweight' but have low body fat.
Source & methodology
Healthy ranges follow WHO adult cut-offs: underweight <18.5, healthy 18.5–24.9, overweight 25–29.9, obese ≥30.

Context that matters
- BMI doesn't separate muscle from fat — many lean, muscular people score above 25.
- Waist circumference and body composition give a more complete picture.
- A doctor can interpret your number alongside other markers.
