A symbol for square foot, square feet, and "per square foot" commonly used in architecture, real estate and interior space plans is a simple square with a vertical line bisecting it. It is also occasionally written as a square with a slash through it.

Famous quotes containing the words square and/or foot:
“If magistrates had true justice, and if physicians had the true art of healing, they would have no occasion for square caps; the majesty of these sciences would of itself be venerable enough. But having only imaginary knowledge, they must employ those silly tools that strike the imagination with which they have to deal; and thereby, in fact, they inspire respect.”
—Blaise Pascal (1623–1662)
“In conversation the game is, to say something new with old words. And you shall observe a man of the people picking his way along, step by step, using every time an old boulder, yet never setting his foot on an old place.”
—Ralph Waldo Emerson (1803–1882)
