The ideal length for the personal statement should be 2 pages, even if the applications furnishes you with more space. It is key to compose the personal statement with one item in mind: draft it so that it resonates with your audience, and more specifically, the cirucmstance of the admissions officer. Therefore, be dynamic and compelling within 2 pages, principally because the admissions committee reads thousands of statements, and because of this, will skim longer essays. Thus, the hallmark should be quality over quantity, and a focused thematic scope.
Best of luck!
