These are the guidelines from the American Council on Exercise (ACE):
Essential Fat: 10-12 percent
Athletes: 14-20 percent
Fitness: 21-24 percent
Acceptable: 25-31 percent
Obese (or high risk): over 32 percent
Hope that helps!
And keep in mind that body fat scales can sometimes be inaccurate and their results vary depending on the time of day and your degree of hydration.
