# Bodyfat - children - skinfold

This procedure estimates bodyfat in children by measuring skinfold at 2 different places.

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

Estimating bodyfat in children by this method is more valid than using BMI or Ponderal index.

Quoting davep33175:
with Slaughter formula there is a small clause you are missing. If the sum of skinfold (tricep and subscapular) is more than 35 mm the formula changes to
Fat (%) = 0.546 (tricep + subsc) + 9.7 otherwise is fine.
Thanks for this great Site

You are right, if the sum>35 there is additional formula. However, the formula you gave is only for *female*. For male:
Fat (%) = 0.783*(tricep + subsc) + 1.7

mm, Morten Z...I was just doing that... looking for the formula and found this site. I do not have net access, where I will be doing the measurements. Therefore I needed the formula.

i want to after find the skin fold measurements apply the formula for children

kindly let me know reference of the calculation of body fat in 2 sites

ya but most of the sources are published articles, so you have to have certain subscriptions or access privileges. I get the NSCA publication, but not a lot of the research is geared toward children. Maybe you have some suggestions for better information?

Matt - to be honest with you - if we just published all the formulas and math behind the calculators, we wouldn't generate much traffic on the site.

We do provide links to references, so it is possible to go to the original sources and extract additional information there.
