    Because pressure is defined as the force/area. Since you've divided out the area, it is independent of area by definition.

    Imagine you have been standing in a crowd of people for hours. How tired your feet get depends on your weight, not the weight of everyone in the crowd. If the crowd gets bigger the "weight per foot" doesn't get any larger.
