A framing square is considered an angle gauge and it’s another type of square tool. The most application of framing square is in carpentry and building such as roofing, stairway, and many more.
Not only for checking 90-degree corners (squareness) but also for layout, marking, and scribing. Therefore, it incorporates some tables and scales that are put on its surface such as a rafter table, octagonal scale, Essex board measure, brace table, etc.
In comparison to machinist squares, although both have one body construction, the framing square has thin body thickness and longer dimensions. On the other hand, in comparison to try squares, framing square doesn’t have a junction between blade and tongue.
The blade and the tongue make up the frame square, which continues at the heel to produce a perfect right angle (90 degrees). The tool’s blade is longer than the tongue, and while the tongue is 1 1/2 inch broad, the blade is 1/2 inch wider.
Framing squares on the market are made of steel or aluminum. There are various brands that produce framing squares such as Johnson, Irwin, Stanley, Starrett, Powertec, etc. These brands let you have broader choices but sometimes it can hurt your time. Here we have selected some framing squares on the market that we think are the best ones to share with you.

Things to Consider Buying A Framing Square
– Aluminum (Lighter and Durable)
When you pick a framing square that is composed of an aluminum alloy, it will be more lightweight than steel-made squares. Working with a light framing tool is easier, more comfortable, and more convenient.
Another advantage is corrosion resistance. Anodized aluminum, to be specific, is more durable and abrasion-resistant. The square made of this material will endure longer and you save money.
The disadvantage is when you carry it outdoor. It can easily absorb heat and feels hot on the palm of your hand. If this square drops onto the floor by mistake, it may generate a little bend.
– Steel (Solid and Heavy)
Steel framing squares, on the other hand, are robust and can endure any form of bending or hard handling. They would keep their squareness for a long time, and you could easily fix them if they become out of the square. They are generally heavy and durable.
However, steel, on the other hand, corrodes quickly and finally renders the tool worthless.
2. Framing Square Size
There are generally 2 sizes of framing squares :
- the large one: the blade and tongue length is 24″ × 12″ respectively
- the smaller one: the blade and length is 12″ × 8″ respectively
Despite the fact that they are commonly used for verifying corner squareness, measuring, checking angles, and a variety of other tasks, their size distinguishes them.
So, if you just need to work on modest size woodworking or carpentry job, the smaller 12 by 8-inch length framing square will suffice. Alternatively, the larger 24-inch by 12-inch framing square will come in helpful for large-scale tasks such as stair and roof building.
In addition to the length and width of the frame square you’ve chosen, the thickness of the square must be considered. Many framing squares give you a thickness of 1/8 inch.
3. The Graduation Quality
Apart from utilizing the framing squares to square edges, they are also used to mark out and measure distance, thus the quality of the graduation is important. You must be able to see the markings clearly and they must be as permanent as possible.
- Stamping: Starrett FS24, Johnson CS5, Irwin 179447, Empire E1190, and Powertec 80008
- Embossing: Stanley 45-300
- Thermal printing: Johnson CS10
- Punch pressing: Vinca SCLS 1208
- Printing: Mr. Pen FR01
This is the most common graduation approach for framing squares. Stamped, embossed, and etched graduations endure longer, while printed graduations may not.
It’s also a good idea to use a framing square with a lot of contrast. This contrast is very useful because it makes graduations visible even in low-light situations.
4. Conversion Tables and Other Information
Some framing squares come with tables, scales, and conversion carts in addition to their graduations.
- brace scale is a series of numbers listed on the backside of the tongue that can be used to determine the length of a knee brace for a beam and post.
- board foot chart can be used to determine the volume in board feet of any plank within the chart’s limit
- rafter tables have commonly used increments for cutting roofs and are ideal for a roof framing carpenter.
