# Is there a medical term for the thickness of the human torso, as measured from its back to its front?

Let's say that you took the measurement of how thick a person's torso is; specifically, by measuring between the following two points:

• the skin on their chest, slightly above the navel

to

• the skin on their back, just outside the spine

This is NOT a measurement of hip or waist circumference, or of how wide across someone is at the hip or the waist Basically, imagine making a measurement between the points indicated in the two circles below.

This measurement provides a rough way to extract hip circumference from hip diameter, since a cross-section of the human trunk/torso region can be approximated as an ellipse.

Google gets plenty of studies on how thick certain organs are, or how wide a person is across the hips, but none about this specific bodily dimension.

I Googled "front-to-back width", "torso thickness", "how thick is the human body", etc., and also tried to figure this out via adding up the depth of the abdominal cavity, the diameter of the spine, the thickness of the skin, etc.

Is there a medical or clinical term for this type of measurement?

• Your question asks for the name of such a measurement. Is that really what you're asking for or are you asking how to measure it? Dec 2, 2021 at 6:11
• @CareyGregory I'm asking for the name of such a measurement. I know how to measure it, and it takes four steps. First, you find the height on the torso at which you want to take the measurement. Second, you take the cross-ways width at that point - i.e. from rib to rib, or love handle to love handle. Third, you take the circumference at that height. Fourth, you plug all that into one of these equations: mathsisfun.com/geometry/ellipse-perimeter.html Dec 2, 2021 at 6:56
• It's the circumference that's usually measured as "(abodminal) girth". This is in fact the medical term. Not sure why you'd want to measure it the way you propose.

• @Fizz No, that's the distance around the abdomen. This is the distance through the abdomen. Dec 2, 2021 at 19:41
• I understand what you're asking, I don't understand why you presuppose that what you're asking for has medical relevance, so that a medical term for it should exist.
