The self-administered Accumeasure Body Fat Caliper retails for under $10 and is sufficient for most people. Tips for Using Body Fat Calipers: For greater accuracy, monitor changes with skinfold measurements rather than converting them into a body fat percentage and using that to judge progress. Have an experienced examiner test you if possible.

For example, a 12-year-old girl in the 5th percentile might have a BMI number between 14.83 and 15.23, according to the Center for Disease Control and Prevention's Body Mass Index for Age Table. The average BMI for 12-year-old girls – the 50th percentile – ranges from 18.01 to 18.63, and the 95th percentile can be 25.27 to 26.13.
Asians with a BMI of 23 or higher may have an increased risk of health problems. For most people, BMI provides a reasonable estimate of body fat. However, BMI doesn't directly measure body fat. Some people, such as muscular athletes, may have a BMI in the obesity category even though they don't have excess body fat.
