# Body Fat (7 Skinfolds) Calculator

### How much of my weight is fat (using 7 skinfold measurements)?

Calculating your body fat percentage by taking some measurements from the fat-storing zones will reveal your fitness level more accurately than scale weight alone. Combine these measurements with your gender, weight, and age and this calculator will find your percent of body fat, how much of your weight is lean mass and how much is fat mass, and your general fitness category.While the water displacement test is the most accurate way to determine body fat percent, skinfold tests are valuable because they can be done at home with the same person measuring each time, providing good measurements to monitor body composition changes over time.

## Field Help

Input Fields

TitleA title for these calculator results that will help you identify it if you have printed out several versions of the calculator.

US/MetricChoose US or Metric units.

Chest
 Use calipers to measure a diagonal fold halfway (male) or two-thirds of the way (female - further from the nipple) between the nipple and the crease of the underarm. The angle of the fold should be along the imaginary line between the nipple and the underarm crease.

Abdomen
 Use calipers to measure a vertical fold about 2 inches (5 cm) directly right or left of your navel.

Thigh
 Use calipers to measure a vertical fold directly on the front of the upper leg and halfway between the knee and the crease created when you lift your leg.

Triceps
 Use calipers to measure a vertical fold directly on the back of the upper arm and halfway between the shoulder and elbow.

Axilla
 Use calipers to measure a vertical or horizontal fold on the side, straight down from the middle of the armpit to the same level as the lowest point of the breast bone (or xiphoid process).

Subscapula
 Use calipers to measure a diagonal fold on the back about 2 cm below the lowest point of the shoulder blade. The fold should be at about a 45 degree angle along an imaginary line from the middle base of the neck toward the outer edge of the hip bone.

Suprailiac
 Use calipers to measure a diagonal fold directly above the hipbone. The angle of the fold should be about the same angle as the hipbone.
