Difference between a Ruler and a Straightedge

There is a big difference between a ruler and a straightedge. A ruler has serrated edges that allow you to make precise measurements, while a straightedge does not have those serrations and can only be used for drawing straight lines. It’s important to know the difference between these two tools when you’re working on your next project!

What is a Ruler?

A ruler is a device used to measure length, usually in the form of a straight edge with markings at regular intervals. The most common type of ruler is the metal ruler, which is made of a strip of metal with markings etched or stamped into it. rulers are also made from wood, plastic, and other materials. The longer the ruler, the more accurate the measurement will be. For example, a four-foot ruler will be more accurate than a two-foot ruler when measuring something that is three feet long.

Rulers are available in a variety of different sizes and lengths to suit different needs. The smallest rulers are typically eight inches long, while the longest can be up to four feet long. Most rulers also have a handle that makes them easy to grip and carry. Some rulers also come with a case or a pouch for storage. Rulers are an essential tool for anyone who needs to measure length, whether it be for school projects, construction work, or other purposes. They are relatively inexpensive and can be found at most stationary stores.

What is a Straightedge?

A straightedge is a tool that is used to draw precise lines or measure distances. It can be made from a variety of materials, including metal, wood, and plastic. A straightedge typically has a smooth, flat surface that is free of any markings or protrusions. This makes it ideal for drawing clean, straight lines. Straightedges are also often used in conjunction with a ruler or measuring tape to measure distances. When used properly, a straightedge can be an invaluable tool for achieving precise results.

Difference between a Ruler and a Straightedge

A ruler is a device used to measure length, whereas a straightedge is a device used to draw or measure straight lines. A ruler typically has markings at regular intervals, making it easy to take precise measurements. A straightedge, on the other hand, is usually unmarked and is used to draw or check for straightness. While a ruler can be used as a straightedge (and vice versa), they are typically used for different purposes. As a result, most people find it helpful to have both a ruler and a straightedge on hand.


A ruler is a tool used to measure length, while a straightedge is an instrument used for drawing perfectly straight lines. They both have their place in the workshop, but they are not interchangeable tools. The next time you need to use a straightedge, don’t reach for your ruler – grab a real straightedge and save yourself some frustration.
