The BMI for Kids Calculator estimates a child’s Body Mass Index (BMI) based on weight, height, age, and gender. It provides a BMI value along with a category—Underweight, Healthy Weight, Overweight, or Obese—to help monitor growth and development. This tool is useful for parents and caregivers to track early health indicators and support discussions with healthcare professionals. BMI assessments for children are interpreted differently than adults and should always be evaluated in conjunction with pediatric guidance.
