The standard deviation is the only parameter of the normal distribution that determines the shape of the curve. Therefore, if lines are drawn perpendicular to the x-axis from the points of inflection (which occur at +/- 1 standard deviation from the mean), these lines will divide the x-axis into segments equal to one standard deviation.
