A ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing and engineering/building to measure distances and/or to rule straight lines. Strictly speaking, the ruler is essentially a straightedge used to rule lines, but typically the ruler also contains calibrated lines to measure distances.

Famous quotes containing the word ruler:
“Despots play their part in the works of thinkers. Fettered words are terrible words. The writer doubles and trebles the power of his writing when a ruler imposes silence on the people. Something emerges from that enforced silence, a mysterious fullness which filters through and becomes steely in the thought. Repression in history leads to conciseness in the historian, and the rocklike hardness of much celebrated prose is due to the tempering of the tyrant.”
—Victor Hugo (1802–1885)
“Can anything be more ridiculous than that a man should have the right to kill me because he lives on the other side of the water, and because his ruler has a quarrel with mine, though I have none with him?”
—Blaise Pascal (1623–1662)
“Know yourself and fit yourself to new fashions. For there is a new ruler among the gods.”
—Aeschylus (525–456 B.C.)
