# Body fat - Skinfold - Durnin and Womersley

Among affordable methods for measuring body fat percentage, using a skinfold caliper is still the best and the four spot formula by Durnin and Womersley is very accurate for most people.

**Instructions:**

1. Measure skinfold in millimeters as indicated on the pictures and enter values.

2. For further instructions see our guide "How to measure body fat with a skinfold caliper"

**Background**

The Durnin & Womersley calculation should be considered valid for people between 17 and 68 years old.

?? the foumula is not working??

Example: biceps 2.5 mm, triceps 8.5mm, subscapular 11.5mm and suprailiac 14.5mm??

i would really apreciate if you can do that.

thanks

My measurements are: 81.5mm (biceps); 25.8mm (triceps); 13.3 (subscap); and 12.6 (suprailiac).

The equation given (female 20-29) is:

density= 1.1599-(0.0717x log of sum of four sites)

(I think we have to use this equation even if outdated)

I'd appreciate any suggestions as my answers at the moment are ranging from 1.021 to 1.076.

Thanks.

The formulas for converting body density to percent body fat for American Indians are:

Males: Age 18-62(4.97/Db)- 4.52

Females: Age 18-60(4.81/Db)-4.34

The basic Durnin & Womersley formulas are the same.

Not sure of the original reference specific for this.

Here is the explanation: Before the modification of the calculator all calculations were based on the formula for age 20-29, because this works best for an athletic population even though the person is above 29. However as this wasn't in agreement with the original source and possibly the calculator is also being used for a non-athletic population, the calculator was changed to use the age-differentia ted formulas.

If you want the same calculation as before, just enter age as 29.

Calculation of Body Density According to the method of Durnin & Womersley

(Biceps, Triceps, Subscapula, and Suprailiac)

Equations for Men

Age range

17-19D = 1.1620 – 0.0630 x (log ∑)

20-29D = 1.1631 – 0.0632 x (log ∑)

30-39D = 1.1422 – 0.0544 x (log ∑)

40-49D = 1.1620 – 0.0700 x (log ∑)

50+D = 1.1715 – 0.0779 x (log ∑)

Equations for Women

Age range

17-19D = 1.1549 – 0.0678 x (log ∑)

20-29D = 1.1599 – 0.0717 x (log ∑)

30-39D = 1.1423 – 0.0632 x (log ∑)

40-49D = 1.1333 – 0.0612 x (log ∑)

50+D = 1.1339 – 0.0645 x (log ∑)

Levels of Body Fatness

Obese 17-62Male(5.00/Db)-4.56

Athletes*High school and college age Male and female(4.57/Db)-4.142

I hope this is detailed enough for everyone.

S = Sum of all four folds

A = age in years

d = 1,1714 - 0.063 * log(S) - 0.000406*A

Bodyfat [%] = 495 / d - 450

Where I can get the formula for D&W equation?

Thanks,
