But first, check out why you should go for the best combination square and the factors that you need to consider before purchasing.

Reasons To Select The Best Combination Square

The combination square is regarded as a necessary tool for metal and stoneworkers.


These are quite useful and versatile since they may be used to gauge the integrity of angles like 90 degrees and 45 degrees, as well as the center of various objects, particularly circular ones.


Additionally, these combination squares make it simple to use a spirit-level vial to determine the level and plumb.


You can see why these tools are essential for creating stone or metalwork now. It is essentially impossible to excel at your stone masonry or woodworking work until you have the best tools in equipment parts, including the combo squares.

Since you will require this combination square for your work, you need to know which one you should purchase in order to complete the task correctly.

How To Find The Best Combination Square?

When looking for the right combination square, make sure to look for these things –

Size Of The Squares

Are you curious to know what constitutes a good combo square? You can choose combination squares that are 4 inches and 12 inches in size.

The most useful size for general use is a 12-inch combination square, which is also one of the most common sizes of the square. But larger variants are also offered.

However, if you prefer to work with something shorter and portable, you should get a 4-inch one.

Types Of Combination Squares – Which One To Get?

There are various options available when it comes to purchasing a combination square for your missionary work.

But you want to choose the perfect one that will fit your requirements and make it easier for you to outline the surface area on board and be accurate at your measurements.

Usually, three types of combination squares are used mostly, and they are 4, 6, and 12-inch lengthy squares.

Now Comes The Question of Which Combination Square to Choose

  • Woodworkers primarily use the four and six-inch double combination squares. These two help them to get more accurate measurements as they are prone to work with intricate designs and aesthetics.
  • Now, if your job involves working with stones and harder surfaces, then you can also go for a 12-inch square, as it will make the process of measuring the surface area easier for you in one go.
  • Also, the 4-inch squares are very much compact to use, and they can be easily carried around while you are traveling. 
  • Depending on the price range, you can choose anything in between these sizes. The smaller one costs less, and the larger one costs a bit higher comparatively.
  • But make sure that all the sides of the squares are equal in length, the interior angles are also equal, and they measure the right angles properly. So the perfect combination square for your needs would be the one that is portable, hardy, and helps you to make the perfect measurements.
