Your BMI is 24.5, in the healthy range.

  • Your healthy weight range for this height is 49.2 to 66.4 kg.
  • Your weight is already inside the healthy range for your height.
  • Women typically carry 6-11% more body fat than men at the same BMI, so BMI thresholds are the same but the underlying body composition differs.
  • BMI is a screening tool, not a diagnosis: it does not distinguish muscle from fat or indicate where fat is stored.

Next stepFor a fuller picture, pair BMI with waist circumference (risk rises above 80 cm for women) and, if available, a body-fat estimate.
