A ruler is an instrument used to measure distances, degrees and determine straight lines. There are many different **types of measurement ruler** available in different shapes, sizes and materials.

These **ruler are used in various occupations and fields of study, such as geometry, the printing, in drawing technical, in construction and in engineering**.

Any of these ruler of measurement is obtained in businesses or warehouses that specialize in things related to plastic arts and drawing. Next, you can learn about the different **types of measurement ruler**.

## The desktop rule

Is the most common type best known ruler and **the ****ruler ****of ****desktop** are generally **used to measure**, **draw ****lines ****straight** and apart, also **serve as guides when cut with knives**.

They have **measurement marks** along each side; They are generally **marked in inches** on one side and **in ****centimeters** in the other. Standard desktop ruler **are 12 inches or 30 centimeters long**.

They can be made of different materials, such as: Wood, plastic or metal, and are available in transparent varieties and opaque shades.

## Line indicators

**Line indicators are ruler used by printers** that resemble desktop ruler, are **marked in dots**, **pikes**, agates and inches. Sometimes **centimeters** are also included.

**The indicators** are made **with stainless steel and have engraved marks**. They are usually **72 pikes or 11**, **952 inches long**. Besides, there is also the **rigid rule** used to prevent any kind of measurement errors.

## The transporter

This is used to **measure angles and circles**, **the conveyors are transparent**, **circular or semicircular ****ruler**. They come in two varieties: **180 degrees** equal to a semicircle or 360 degrees that is a complete circle.

**To measure an angle**, the conveyors **have two sets of units of degrees** of operation along the curve, which go in opposite directions. These grade units generally mark in half-degree increments.

On the other hand, **the conveyors** are available in **three different sizes**: The 6-inch or 15-centimeter conveyor, the 8-inch or 20-centimeter conveyor and the 10-inch or 25-centimeter long conveyor.

## The drafting triangles

Drafting triangles, usually made of transparent plastic, are used to **measure ****angles** and **draw ****vertical** or **inclined ****lines**.

The two types available, **the triangle of 45 degrees** and **the triangle 30** / **60 degrees**, are appointed by the size of its angles; **acute** or **small**.

**The 45 degree triangle** has an angle of 90 degrees and two angles of 45 degrees; **Triangle 30** / **60 degrees** has a 90, a 30 and a 60 degrees. **Drafting triangles** are available in **sizes** ranging **from 4 to 18 inches** equal to 10 to 45 centimeters long.

## Adjustable triangle

The combination between the functions of the conveyors and the drafting **triangles** are the **adjustable triangles** that **can be adjusted and locked at any angle**.

The degrees of an angle, can mark in increments of half degree, are in the part of the conveyor and locked in position. **The triangle portion can be used to draw the selected angle**.

## The ruler at triangular scales

The triangular scale ruler are devices that are **triangular measuring scales**, are used by **architects**, **engineers**, **builders** and **designers**.

They are **marked with a range of scales or proportions**, which **are used for manufacturing or small scale measurement as blueprints or plans**. Remember that a cartoonist or architect can use the different types of paper known.

In the United States, the proportions of these ruler are usually marked as inches. Unlike in other parts of the planet, relationships are marked in metric terms, such as millimeters, centimeters and meters. They have 10 to 12 scales available and are 12 inches equal to 30 cm long.

## The scales used in an architectural plan

A professional architect must have all the knowledge about **the scales used in an architectural plan** to carry out the works that he has to create. Remember that a well-made construction can last for decades.

Therefore, these experts in the field know how to transform a design from **large scales to small scales** within a plane. Keep in mind, that **the scales are divided into 3 types**.

The first of these is the **reduction scale**, which, as its name says, reduces all measures. The other is the **scale of enlargement**, which expands all measures and finally, the **natural scale** or **1 to 1**. This works with the same measures of drawing in reality.
