# Ideal body weight calculator > A realistic target range for your build. The range maps the healthy BMI band of 18.5 to 24.9 to your height. Bodies differ, so treat the edges softly. A target just above the range can be the right call for a muscular build. _These numbers are general guidance, not medical advice. Talk to a doctor or dietitian before making big changes, especially with a medical condition, during pregnancy, or with a history of disordered eating._
