Well if u wanted to look at this scientifically u could find your BMI http://www.nhlbisupport.com/bmi/ There are more complicated ones that take in gender, activity, and age but if u want a quick idea of it there you go. Also remember these are generalities not correct for everyone.
But beyond fat or not there the more base question: Are you healthy?
All any of us can really hope for is to be healthy.
BMI is NOT scientifically accurate. Muscle weighs more than fat. Think about it this way, most body-builders are "obese" on the BMI scale, even though usually they have very little fat. But if you are an average person, this shouldn't matter much.
