How to Buy the Best Woodworking Squares

1. Your Purpose

How you intend to use the woodworking square is perhaps the primary determinant of the right one for you as they come in various types.

Speed squares like the Swanson Tool Co SW1201K are among the most common types, and they are the best choice when you want something you can use to mark lumber for precise cuts.

Combination squares such as the Irwin 1794469 come in handy if most of your jobs entail marking 90 and 45-degree angles. But for woodworkers that are more into framing jobs, a framing square like the Milescraft 8410 is always a better buy.

Various other square types like try, rafter, and sliding t-bevel squares are meant for different purposes. Hence, before you start shopping for a woodworking square, you have to decide how you intend to use it.

2. Precision

For any square to work well for you, it needs to offer precise measurements. Contrary to what many people assume, some squares can be a bit off, which in most instances is due to poor manufacturing.

Therefore, before settling on a square, make sure the angles and measurements are true. The best way to check this is by measuring the square against lumber with a straight edge. Reading customer reviews and feedback can also give you an idea of a square's precision before buying.

3. Material

The material needs to be at the top of your mind when shopping for a woodworking square. Material determines the durability of the square and its ability to handle the abuse that comes with use in the workshop.

Additionally, the material also affects the markings and overall feel of the square. That said, the best ones are made from heavy-duty materials like stainless steel, aluminum, and carbon steel.

4. Length

A square's length determines the maximum measurements you can use it to make. Therefore, as you shop for the best woodworking square, you need to make sure you know the maximum length you are likely to measure.

You can get squares that are anything from 3-inch to over 12 inches long. The smaller 3-inch models are ideal for simple, small-scale projects, while the longer ones are best suited for the huge ones where you deal with larger workpieces.

5. Marking and Measurement Types

The markings on your woodworking square are perhaps the most vital factor to consider as they determine how accurate the tool will be for you.

Besides being precisely marked, they also need to be durable to ensure you get to use the square long enough. Markings that are etched on the tool are always better than those printed on it as they will not wear or fade quickly.

Another critical factor to consider is the measurement types. Most squares provide measurements in inches using different graduations like 1/8, 1/16, 1/32, and 1/64. Many will also have them in millimeters to give you more options. The most important thing is to make sure the tool uses measurement types you can easily understand or are comfortable with.

6. Comfort

Like any other handheld tool, the woodworking squares need to be comfortable when using. Comfort is mainly associated with the handle on the square. Something made from soft materials like wood or rubber is always preferable.

Apart from the handle material, the handle has to be the right size to fit your hand perfectly. Furthermore, the overall weight of the tool affects its comfort, and here the lighter it is, the better.

Conclusion 

Woodworking squares will come in handy for most of your projects. But, it is vital to make sure you choose the right type and model for your specific jobs.

That said, the Swanson Tool Co SW1201K is our top overall recommendation. This speed square is well-built with heavy-duty material, versatile, and comes with a clearly identifiable scale.

However, if you are looking for something that will give you the best value for your money, go for Mr. Pen FR01. It is a premium-quality square that comes at a great price.
