Combination Square vs Speed Square

A combination square is a tool used for various purposes like woodworking, stone masonry, and metalworking. It is composed of a ruler, and attached to it is an interchangeable head that can be one or more in number. Whereas a speed square is a triangular-shaped tool that can perform a combination square, try square, and framing square as a single tool.

  • The most simple use of speed squares would be to draw geometrical figures.
  • Next, it can be used as a ruler for measurement, trim edges of surfaces, or as a saw guide.
  • A speed square is also used as a line scriber. It can also mark parallel lines.
  • It can also be used for ripping wood and measuring saw blades.

What to Look for in a Speed Square while Purchasing?

While you are buying any speed square, there are certain features that you should always keep in mind. They mainly include the building material of the products, the clear visibility of the graduation marks, perfection in measuring angles, the price of the speed square, and the warranty period that the company from which you are purchasing a speed square offers to you.

Product Material

Well, most speed squares are made of aluminum or aluminum alloy, durable, strong, and rust-free. However, there are also speed squares available in the market which are not made of aluminum but of other materials which look similar. So always make sure that the speed square you are buying is of aluminum or other long-lasting material so that your tool will remain for longer periods.

Clear Graduation Mark

This is one of the most important features you should consider while buying a speed square of any kind. Check firmly whether the gradation scale is correct or not, and most importantly, it is visible. Because if the gradation scale is not proper, then the whole purpose of having it will be useless as it won’t give you appropriate and accurate marks.

Accuracy In Measuring Angles

The main purpose of having a speed square is to give accurate angle measurements for different purposes like stair building, rafting, woodworking, or frameworking. If the angles are inaccurate,n the build-ups will be heavily affected and will be of no further use. Hence, check before buying that the speed square gives precise angle measurements.


Well, this is a factor that everyone keeps in mind while purchasing. The price of the speed squares mainly depends on the brand and the unique features of the customers. If you are in need of a speed square with very recent technology covering all the features, then definitely the pricing will be higher. But if you are looking for a simple one, it’s better to go for a lower range.


Whether you buy a low-budget speed square or high-budget ones, always make sure to check the warranty period that the company is offering you. Being a carpentry tool, there are chances of graduations getting blurred or the edges becoming blunt just after a few days of use. So in these cases, you can go to the company and get the speed square repaired or replaced.
