In brief: 19-25

A normal bmi is between 18.
9-24.9 the calculation doesn't factor age or gender into equation. Bmi is a calculation utilizing weight and height. Height and weight can vary greatly and still be considered normal. Bmi can only vary between 18.9-24.9 to be considered normal. As we get older, it is somewhat preferable to be on the higher side to offer more protection to the bony structures and organs.
