A useful metal bar for a variety of needs

The main use of the ruler is as a measuring instrument designed to measure the length of short / medium lines. Rulers are most often used to measure distances that do not require very high accuracy (less than a millimeter) or a particularly large length (other than two or three meters, other distance measurement methods should be used).

The ruler is a tool that allows the creation of a straight line or a long section that passes through two given points. In geometry, the ruler is used for drawing purposes and is not used for measurement. In Euclidean geometry of the plane, construction in a ruler and compass is the construction of geometric objects, such as segments with definite properties, that use only the ruler and compass.

Being a lightweight and elongated object the ruler can help keep track of lines of written texts. This is essential for reading ability which is part of literacy skills. The use of the bar can help elementary school students in the early stages of reading acquisition and people with reading difficulties due to various causes such as dyslexia, attention deficit disorder and difficulty focusing vision.
