Plastics have also been used since they were invented they can be molded with length markings instead of being scribed. Rulers have long been made from different materials and in multiple sizes. Since much technical work is now done on computer, many software programs implement virtual rulers to help the user estimate virtual distances.īronze ruler. Rulers are ubiquitous in the engineering and construction industries, often in the form of a tape measure, and are used for making and reading technical drawings. At the high school level rulers are often used as straightedges for geometric constructions in Euclidean geometry. Children learn basic use of rulers at the elementary school level and are often part of a student's school supplies. Their ability to quickly and easily measure lengths makes them important to textile industry and to retailers where amounts of string, fabric, and paper goods can be cut to size. They are crucially important tools in the design and construction of buildings. They are commonly made from metal, wood, fabric, paper, and plastic. Rulers have been used since ancient times. Specialty rulers exist that have flexible edges that retain a chosen shape and these find use in sewing, arts, and crafts. Some rulers such as cloth or paper tape measures are non-rigid. Commonly the instrument is rigid and the edge itself is a straightedge ("ruled straightedge") which additionally allows one to draw straight lines. If you found this site useful can do me a favor and help others by sharing it? Thanks you.A ruler in combination with a letter scaleĪ ruler, sometimes called a rule, line gauge, or scale, is an instrument used to make distance measurements whereby a user estimates a distance by reading from a series of markings called "rules" along an edge of the device. You can use it to play the dot game with dots, this works when the grid lines are very light, that allows you to use a pen or pencil to darken them, also it helps if the grids are large. You can use it to create crossword puzzles. You can fill in blocks in black or color to create graph art. Also a block can help children separate words which is helpful since children often have problems with spacing. Letters that dip under the line like the lowercase "p", "g", and "y" can take up the bottom two rows. Lowercase letters should take up only the second row. Capital letters can take up the top two rows. For example you can use a three block row. It can also be used as a writing aid, specially for children learning to write. Graph papers keep those number neat and aligned. ![]() Having multiple numbers in a small space can make it confusing to determine which numbers should be added, subtracted, multiplied, etc. You can also use it to do multi digit math. Instead of placing the ruler on the object you can place the object on the paper. You can use graph paper as a two dimensional ruler. For example to plot and study lines, functions, and data. This makes graph paper ideal for taking notes on math related subjects. Graph paper is available in many different measurements, for example each box can be centimeter or an inch in length.įor example anything using the cartesian system can make use of graph paper since the cartesian system is essentially a grid. Graph paper is useful when you want to draw things to some kind of scale, instead of measuring each line with a ruler as you draw it you let the graph paper serve as a guide. It is made of up fine lines arranged vertically and horizontally as to create many small boxes. Graph paper is paper meant to be written and drawn on. If you would like to see the graph paper listed by type you can go to one of these links: Are you looking for a particular size graph paper?Įvery type of graph paper we offer comes in different paper sizes and orientations.
