A ruler is typically made from materials such as plastic, wood, metal, or a combination of these materials, depending on its intended use. Common types include plastic rulers for school use, wooden rulers for drafting, and metal rulers for precision in various applications. Each material offers different advantages in terms of durability, flexibility, and accuracy.
Accuracy has more to do with the measurement lines on the ruler than the material. In terms of making measurements , however, a steel ruler has several advantages to a plastic ruler of the same accuracy. For starters, steel rulers are often thinner than plastic rulers, positioning the measurement lines closer to the paper. As well as this, many steel rulers feature a backing made of a gripping material such as cork, which keeps the ruler firmly planted while drawing lines and making measurements. Lastly, the measurement lines on steel rulers are frequently embedded into the metal, whereas plastic rulers tend to have the lines painted on. After a while, these marks can be worn away, reducing the accuracy and readability of a plastic ruler.
