What Are the Two Basic Types of Squares That Every Carpentry Must Have
The two basic types of squares that every carpenter must have are the steel square and the framing square.
The steel square is a long-armed square made of steel and is used for measuring right angles and various angles.
It has a longer wider arm called the blade and a shorter narrower arm called the tongue.
The steel square has many uses in carpentry, including laying out rafters and stairs.
The framing square, also known as the carpenter’s square, is similar to the steel square but can be made of different materials.
It is used for measuring and marking right angles and can also be used as winding sticks.
Did You Know?
1. The first basic type of square that every carpenter must have is the framing square, also known as a rafter square. This versatile tool not only helps carpenters lay out right angles but also assists in determining pitch, cutting rafter tails, and measuring angles.
2. The second basic type of square is the try square, which is used for checking the accuracy of perpendicular cuts and making square cuts on smaller pieces of wood. Interestingly, this tool gets its name from the word “try,” meaning to test or make an attempt, indicating its purpose in verifying the accuracy of angles.
3. Did you know that the framing square, despite being a go-to tool for carpentry, has origins dating back to ancient Egypt? Some evidence suggests that similar tools were used by ancient Egyptians for various geometric purposes, including measuring right angles, aligning surfaces, and even constructing pyramids.
4. The try square, on the other hand, has a rich history closely tied to the development of precision engineering. This tool was commonly used by ancient Greeks and Romans to ensure right angles in architectural designs, particularly in the construction of buildings and monuments.
5. Although these two basic types of squares are essential for carpentry, there is a wide range of specialized squares that serve specific purposes in different carpentry tasks. For example, there are miter squares for accurately measuring and marking angles typically used in joinery work, combination squares that combine multiple measuring functions, and even speed squares used for quick and precise measurements on rafters and stair stringers.
Steel Square: A Versatile Tool For Measuring Angles
One of the most essential tools in carpentry is the steel square, also known as a framing square. It is a long-armed square made of steel, but it can also be made of aluminum or polymers. This versatile tool is primarily used for measuring right angles and various angles in carpentry projects.
The steel square consists of two arms – a longer, wider arm called the blade and a shorter, narrower arm called the tongue. The blade is typically 50 millimeters wide, while the tongue is 37 millimeters wide. These dimensions help carpenters accurately measure and mark angles for precise cuts and layouts.
In addition to measuring angles, the steel square has many other functions in carpentry. It is commonly used for:
- Laying out common rafters
- Laying out hip rafters
- Laying out stairs
The steel square also features a diagonal scale, board foot scale, and octagonal scale for further measurement versatility.

Framing Square: Essential For Carpentry Projects
An indispensable tool for carpenters, the framing square is essentially a type of steel square. While the steel square can be made of different materials, the framing square is specifically designed for carpentry projects. It serves as a reliable reference for right angles and is commonly used in tasks such as marking out stud placements, checking for squareness, and laying out roof rafters and stairs.
The framing square, like the steel square, consists of a blade and a tongue. Its larger dimensions provide additional stability and accuracy when measuring and marking angles. Some framing squares may even feature additional markings and scales, such as rafter tables, that are specific to carpentry projects.
With its versatility and precision, the framing square is an essential tool that every carpenter must have in their toolbox. It ensures accurate measurements and helps achieve the desired level of precision in carpentry projects.
Set Square: Ensuring Precision In Layout Lines And Cuts
Another important tool in carpentry is the set square, sometimes referred to as a try square. This square is specifically designed to ensure accuracy in layout lines and cuts.
The set square is primarily used for marking out right angles and straight lines. It is also incredibly useful for checking the straightness of edges and ensuring precise cuts. Carpenters rely on the set square to achieve clean, crisp edges and maintain the integrity of their woodworking projects.
Unlike the steel square and framing square, the set square does not have additional adjustable features. It is a fixed square that is set at a 90° angle. This fixed position allows for consistent and accurate measurements without the need for adjustment.
Combination Square: Adjustable And Multi-Functional
In carpentry, the combination square is a highly versatile tool that offers adjustability and multiple functions. It consists of a head that can be moved along the beam, allowing for precise measurements at various angles.
The combination square typically has measurements marked on the beam, enabling carpenters to measure and mark specific lengths accurately. It also has a 45° aspect in addition to the 90° position, making it useful for tasks that involve angles other than right angles.
With its adjustability and multiple functions, the combination square is an invaluable tool in carpentry. Carpenters can rely on it for accurate measurements, angle layouts, and marking precise cuts.
Try Square: A Fixed 90° Angle Square
The try square, also known as a tri square, is a square that is specifically designed to have a fixed position at a 90° angle. Unlike the combination square, it does not have a movable head.
Due to its fixed position, the try square is ideal for tasks that require consistent right angles. Carpenters often use this square to check the squareness of their workpieces or mark right angles for accurate cuts.
While it may seem similar to the set square, the try square is typically smaller and provides a single fixed angle of 90°. This simplicity and reliability make the try square an essential tool for carpentry, ensuring precise measurements and maintaining the integrity of woodworking projects.

Frequently Asked Questions
What are the different types of squares in carpentry?
In the world of carpentry, squares come in various types, each designed to serve a specific purpose. One type is the speed square, famous for its versatility and efficiency. It not only helps establish right angles but also allows carpenters to quickly measure and mark angles, making it a must-have tool for any project. Another type is the try square, which focuses solely on creating perfect right angles. With its L-shape design and accurate measurements, carpenters rely on try squares to ensure precise and squared cuts. Lastly, there is the combination square, which goes beyond measuring angles. It features a ruler, a spirit level, and a scriber, making it a versatile tool for measuring, marking, and aligning in various carpentry tasks.
What square do carpenters use?
Carpenters commonly use a framing square, also known as a steel square, to aid in their work. This versatile tool proves invaluable in carpentry tasks such as framing, laying rafters, and building stairs. Additionally, it serves as a straight-edge, enabling the carpenter to identify and establish right angles and precisely mark cut-off work on wide stock.
What are the two most common uses for a try square?
A try square, commonly used in woodworking and carpentry, serves two main purposes. Firstly, it is often employed to mark lines that are perfectly perpendicular to the edge of a board. By aligning the try square along the edge and using it as a guide, craftsmen can ensure precise and accurate perpendicular markings. Additionally, a try square is frequently used to check if the entire length of a board is square. By placing the try square against the board’s length, carpenters can detect any irregularities or deviations from a 90-degree angle, ensuring the quality and accuracy of their work.
What type of square are you most likely to use for second fix carpentry?
When it comes to second fix carpentry, the square that is most commonly used is the combination square. While cabinetmakers often prefer the fixed square for checking corners and edges, the combination square offers more versatility for various carpentry tasks. Its design, with a long blade and a shorter, narrower tongue, is particularly useful when marking up wide boards and sheet stock or ensuring their squareness.
