What to Look for When Picking a Woodworking Square

woodworking plan

As is evident from the list above, there are several types of woodworking squares. Chances are, you will have a need for all of them at some point of time. Before we go into what to look for in a woodworking square, let us look at all the types that are available. 

Types of Woodworking Squares

  • Combination square. Also known as a sliding square, this tool has a ruler with an anvil attached. The anvil slides across the scale. It can be used for marking, measuring 45 degree angles, and making sure if something is at an angle of 90 degrees.
  • Try square. Also known as a tri-square, this tool consists of a metal blade and a stock. It is used to check if objects are square in relation to each other. In short, it measures and marks 90 degree angles. 
  • Speed square. Also known as a rafter square and a triangle square, this tool actually has several uses and is an invaluable addition to a carpenter’s toolbox. It can be used to measure, mark, and even scribe angles. 
  • Framing square. Also known as a carpenter’s square, this tool is L shaped and is used to mark angles and cuts and for other construction measurements. 
  • Double square. This tool is used to measure 90 degree angles in pairs of two. It is used whenever a pattern needs to be maintained. 

So, these are the 5 types of woodworking squares. The next stop is learning what to look for when choosing a woodworking square. 


The point of a woodworking square is precision and accuracy.

Your tool needs to be perfectly square and must have accurate measurements.

Even a slight variation will cause your entire project to derail. 

Markings and Measurement Types 

The second most important thing is to make sure that the markings are permanently etched on to the blade and are clearly visible. Otherwise, they will wear off after some time and you won’t be able to take accurate measurements. 

Many tools sold in the U.S tend to have imperial markings. If you use metric, you can use a conversion scale or look for other tools that feature a metric system. 

Blade Length

This depends on the amount of area you want to cover while taking measurements.

Tools with a smaller blade length are easy to carry around but won’t cover as much area as the longer ones. But the longer ones might pose problems if you are measuring tight spaces.

My recommendation is that you can go for tools of various lengths if you have the need for it. 

Build Material and Durability

Your woodworking square should be well-built and last you a long time. Nobody wants to keep shelling out money periodically for the same thing, right? 

Most woodworking square blades are made using aluminum or stainless steel. Both options make the tool durable. But do make sure that they are protected against oxidation and rust. 

And.. that’s it! Choose the type of woodworking square you need based on your project and start making accurate measurements. Happy woodworking!
