Have you ever been told that you’ve got a "big ole head"? Or do you have the opposite problem – perhaps even the x-small helmets still slip right off?
In this blog post, we’ll give you the numbers to prove or disprove your suspicions, and figure out how massive your head is compared to everyone else!
On our DXA scan reports, we don’t track fat and lean tissue changes in the head separately, since we don’t typically train the head. But the reports give you all the data needed to calculate the mass of your head. Here’s how!
Let's take a look at a sample scan as an example.
Head mass = A – B – C – D = 135.8 lbs – 16.6 lbs – 54.0 lbs – 55.3 lbs = 9.9 lbs
So now that you've figured out the size of your head, how does it stack up? Here’s a handy percentile chart to find out.
Within your gender row, go across until you find the range in which your calculated head mass falls. Then look to the top row of the chart for your quintile.
So the 9.9 lb head from the example above would be in the 0% – 20% percentile range if it were a male head – very small!
However, if it were a female head, it would be in the 60% - 80% percentile range, considered a bit larger than average.
Even if your head isn’t big on its own, it may still look big if you’ve got a relatively large head compared to your body!
To calculate your head-to-body-mass ratio, all you have to do is divide your head mass by your total body mass.
Using the same example from above:
Head to body mass ratio = 9.9 lbs / A = 9.9 lbs / 135.8 lbs = 7.29%
In this situation, this individual’s head only comprises 7.29% of his or her total body mass. Compare that to this mola mola, whose body looks like it’s about 80% head.
We’ve provided a percentile table for a head-to-body-mass ratio so you can see how you compare!
