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:
“Know yourself and fit yourself to new fashions. For there is a new ruler among the gods.”
—Aeschylus (525456 B.C.)
“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 (18021885)
“The mob in silence leaves their princes side,
And to the coming ruler gives its love,
And is with mobs the custom.”
—Publius Papinius Statius (c. 4096)
