The Gill Sans alphabet is classical in proportion. It is classified as a "humanist" sans serif, making it very legible and readable in text and display work. This makes it better suited than most sans serif typefaces to setting bodies of text. The humanist movement, which occurred during the Renaissance, reacquainted society with art, literature and education. The first writing styles to come out of the movement took the upright shapes of Textura and introduced roundness and uniformity. Gill Sans, influenced by this period, uses the classic forms of "a" and "g". The rounded "c," "e" and "f" are the first examples of vertical stroke ends, which create the optical effect of the stroke thinning towards the ending, alluding to Roman type.
