Head Circumference
The circumference of the head of a character may be relevant when a character finds a helmet or
hat and desires to wear it. Head Circumference is listed in inches. It is impossible for a character to wear
a hat or helmet that is smaller than the character’s Head Circumference. The hat or helmet is comfortable
if it is not larger than 101% of the character’s Head Circumference. It is possible to wear a hat or helmet
if it is between 102% and 103% of the character’s Head Circumference, though the loose fit will be
annoying. If the hat or helmet is larger than this, then it is impractical to wear it.
To determine the Base Head Circumference of an adult, roll 1d100 and consult the following
table:

Chapter 2: Body
The table above produces male Base Head Circumference. If female, multiply the result by 0.97.
Finally, the base must be modified randomly. Roll 1d100. If 01-50, then the Base Head Circumference
will be decreased. If 51-100, then the Base Head Circumference will be increased. Roll 1d100, and add or
subtract the result as hundredths of an inch.
1. Head circumference and intelligence are uncorrelated, although intelligence is correlated with brain size. The relationship
between intelligence and brain size occurs in at least 3 studies appearing in scholarly journals. See the References section at the
