However, no equations are available for estimating body fat from a single-site skinfold measurement. WHO triceps skinfold thickness for age) are available for comparison. The triceps site is the most commonly used single-site skinfold measurement as it is easy to measure and reference data (e.g. In a similar way to body mass index (BMI), they can be converted into standard deviation scores (SDS) for longitudinal evaluations. Raw skinfold thickness values are often used and they act as reliable indicators of regional fatness. The skinfold thickness values should be quality checked during data processing in the same manner as other health related variables, for example by checking for outliers and data entry errors. Skinfold thickness are typically recorded in mm.

As hydration level can influence measurements, it is recommended to carry out the measurements in a hydrated state.

Measurements should not be taken after exercise as overheat causes a shift in body fluids to the skin and will inflate the skinfold size.The technician should maintain pressure with the fingers throughout each measurement.Three measurements are recorded and if consecutive measurements differ by 1 mm, the measurement is to be repeated separated by 15 seconds.Measurement is recorded to the nearest 0.2 mm.4 seconds after the pressure from the measurer’s hand has been released on the lever arm of the caliper. The caliper tip should be 1 cm distal from the fingers holding the skinfold.The caliper is in the right hand (perpendicular to the axis of the skinfold and with dial facing up).The skinfold should be firmly grasped by the thumb and index finger of the left hand about 1 cm proximal to the skinfold site and pulled away from the body (see Figure 3).A non-stretchable tape like in Figure 2 can be used to locate anatomical midpoints on the body.The site to be measured is marked once identified.When selecting the side it is important to be consistent. It is standard to take measurements to the right side in the US, to the left side in Europe.

A vertical fold taken at the widest point of the calf at the medial (inner) aspect of the calf. Medial Calf: The foot is placed flat on an elevated surface with the knee flexed at a 90° angle.Subscapular: A diagonal fold just below the inferior angle of the scapula.Biceps: A vertical pinch mid-biceps at the same level the triceps skinfold was taken.Triceps: A vertical fold midway between the acromion process and the olecranon process (elbow).Quadriceps or mid-thigh: A vertical fold midway between the knee and top of the thigh (between the inguinal crease and the proximal border of the patella).Abdominal: A horizontal fold about 3 cm to the side of the midpoint of the umbilicus and 1 cm below it.Supra-iliac or flank: A diagonal fold just above the front forward protrusion of the hip bone (just above the iliac crest at the midaxillary line).Mid-Axillary: A vertical fold on the mid-axillary line which runs directly down from the center of the armpit.In women, a diagonal fold 1/3 of the way from the arm pit to the nipple. Chest or pectoral skinfold: For men, get a diagonal fold half way between the armpit and the nipple.The following are the nine anatomical sites (as illustrated in Figure 2) that are most commonly used in the assessment of skinfold thickness:
