Best Ruler

The ruler is the most familiar linear measurement tool in our life. It’s easy to find and generally affordable. People use a ruler to draw a line with a certain defined length. In addition, it functions to measure a linear distance between two spots.

Commonly, a ruler comes in imperial (inch) and metric (cm) reading. The graduation is a tenth of a centimeter or tenth of an inch. A ruler for school kids has a typical length of 30cm. It may be different for other purposes. Some are made from metal, some are also made from plastic or wood. Even, some of them are flexible which means made of special material.

In this post, we are going to present some options for you about the best ruler on the market.

How to Choose the Best Ruler for your Needs

1. Material

It’s important to consider the material of the ruler you are going to pick. If it’s made from metal, it is probably stiff. It could be a little bit flexible but not intended to be a flexible ruler. The plastic one may be great to choose from but it’s sort of easy to break. Another material is wood. Although it’s lightweight and safe for children, it’s easy to ruin the accuracy. For professional use, then we recommend using the metal ones.

2. Accuracy

Accuracy is important for serious measurement. In this case, you have to be able to differentiate between accuracy in two different terms. Firstly, it’s about how exactly the same it is with the standard ruler. Secondly, it’s about graduation.

We don’t know how traceable to the standard length the ruler is. A certificate of traceability is absolutely required. However, when it comes to graduation, the high quality marking etcher is the key. The smaller the graduation it provides, the better it’s in terms of accuracy. For engineering, mechanics, and architects, this is important. For school, office, and home use, the general 8th graduation is decent.

3. Length

There are several options available in this case. You could pick up the 6 inch one or the longer ones. This is actually about your needs.

4. Laser Engraved Markings

The graduation is marked with linear lines and numbers. These marks can easily fade out due to wear and a long period of use. The printed markings are considered easy to become blurry and fade out. Therefore, we suggest preferring the engraved one.


That’s all that we present on this page. It’s actually not too overwhelming to choose the best ruler as there are decent options available on the market and their quality competes with each other. These are just our preferences but should be useful to give you a quick list of selections. Whether it’s for school, office, engineering, mechanics, or architects, the products are on the list.

However, if you still have no idea what to choose from, we recommend the Mitutoyo ruler for everyday use. It’s highly durable and accurate. If you are familiar with imperial, then Starrett is amazingly a great pick. There are 4 graduations to switch that make it versatile in any condition. For the budget option, you could buy the eboot ruler.

If you require to check whether its graduation is accurate or not, you could buy a precision ruler and then compare the graduation. The same thing goes the same with any tool that comes with a ruler such as double square, combination square, etc.
