Measuring the head is
a starting point for the entire sizing procedure. Due to varying shapes,
heads that are apparently the same size when measured by a tape may not
necessarily fit the same size helmet.
A small metal tape
measure, or a cloth tape may be used to make your initial measurement.
The circumference
of the head should be measured at a point approximately one inch above
the eyebrows in front, and at a point in the back of the head that results
in the largest possible measurement. Take several measurements, to make
sure you have the largest one.
PLEASE NOTE THAT THIS IS A ROUGH GUIDE AND NOT EXACT. THE SHAPE OF YOUR HEAD IS AS IMPORTANT AS THE MEASUREMENT WHICH MAY AFFECT FINAL FIT!
