What is a Speed Square

If you do any kind of work or projects around your home, a speed square is a great addition for your tool bag.

Although they call it a square, it really is a triangular-shaped, carpenters’ mark out tool. The tool was first manufactured and sold by Swanson Tool Co. Inc, back in 1928.

The Speed Square combines some of the common functions of the framing square, try square, and combination square built into one tool. It was originally designed for craftsmen for laying out rafters and stair stringers quickly.

Mine is always in my tool pouch and is one of my most used tools. I find the most use I get from my speed square is as a saw guide for my circular saw or jig saw when making quick 45 and 90 degree cuts.

As you start to use one, you will find the speed square is useful for so many thing besides just cutting boards. It is an awesome tool to have when you are doing tile work, making furniture, installing doors and windows, fixing a gate and so much more.

The speed square comes in standard 7 inch and also 12 inch for bigger projects.

  1. I have one in my tool cache… I’ll be one to admit I don’t know how to use half of the features it provides. The ones in this video though, I have that down. As far as the folks commenting on people not knowing how to use one and hiring someone… there is a bowl of dicks somewhere with your name in it to much on.. go find it and enjoy yourself. I’d rather do it my damn self and maybe$#%&!@*up a few cuts than use a dipshit “professional” with your attitudes.

  2. I’ve been a carpenter 23 years when I started we used a 2′ framing square. The speed square is a useful tool that I use 100 or more times a day. Its saves so much time. when I need a level cut on a 10/12 and a seat cut on a 8/12. I can mark the level and get the number of degrees for my seat cut to set saw for the bevel. Very efficient tool.

  3. An equilateral triangle has three equal lenth sides and is also equi-angular. A right triangle has one 90° angle. So therefore a right triangle, which is what a swanson speed square is, cannot be an equilateral triangle.

  4. My only complaint with any speed square is that is only 7″ long. 2x8s float around 7and 1/4″ why not make them 7 and 1/2 when seated in the 90 degree position? I know I’d buy one a whistle bigger.

  6. Great story about speed square:
    I was working with my nine year old daughter on a woodworking project. I asked her ” honey can you hand me that square?” She looked around all confused at what I was pointing at. So I just reached over and grabbed the square. She says to me “daddy that’s not a square, that’s a triangle.”
