what should your bmi be
A separate BMI Percentile Calculator should be used for children and teens that takes a childâs age and gender into consideration. BMI stands for Body Mass Index. This is a numerical value of your weight in relation to your height. A BMI between 18.5 and 25 kg/mÂ² indicates a normal weight. A BMI of less than 18.5 kg/mÂ² is considered underweight. A BMI between 25 kg/mÂ² and 29.9 kg/mÂ² is considered overweight.
