You'll need someone to measure you with this caliper. Other models of tai body fat calipers (if you want to splurge), range from $150 to $450. (At our health clubs, I use the electronic "SKYNDEX" caliper with the 4-site "Durnin formula.") The calipers come with instructions, or you can use these formulas, which I have used and found to be very accurate: 4 tai Site formula for men (abdomen, suprailiac, thigh, tricep) % fat = .29288(sum of 4 skinfolds) - 0.0005(sum of four skinfolds squared) + 0.15845(age) - 5.76377 4-Site Formula for women (abdomen, suprailiac, thigh, tricep) % tai Fat = (.29669)(sum of 4 skinfolds) - (.00043)(Sum of four skinfolds squared) + .02963(age) + 1.4072 Source: Jackson A S, Pollock, M (1985) Practical assessment of body composition. Physician Sport Med. 13: 76-90. Body fat percentages vary based on age and gender, but 20-25% body fat is average for women (15-19% is ideal), while 15-20% is average for men (10-14% is ideal).
