    A drywall T-square is specifically designed for cutting drywall or plasterboard. It’s larger than a regular T-square due to the size of the materials worked with. The tool consists of a long blade and a short stock or head, forming a 'T' shape. The T-square is placed against the edge of the drywall, where the blade runs down the surface. After marking the desired cut location using the blade's hash marks, the T-square serves as a guide for the utility knife to make the cut​. When selecting T-squares for hanging drywall, there are several preferred features to consider for optimal use and efficiency. Drywall T-squares are invaluable tools, primarily made of aluminum due to its lightweight and resistance to rusting. Anodized aluminum finishes are important, providing a rust-free and corrosion-resistant service life, while ensuring the tool remains easy to clean and maintain. They are specifically designed to aid in cutting and installing drywall panels, offering a straight edge for precision cutting with a utility knife. The most common size for these T-squares is 48 inches to match the height of most drywall panels, although 54-inch models are also available for use with 54-inch boards​.

    Key features to look for in a good drywall T-square include:

    • Material Thickness: Opt for T-squares made with thicker 3/16-inch aluminum for increased stiffness and durability. Thicker metal provides a more stable edge and prevents the utility knife from slipping off the cutting side​​.
    • Accuracy: For any drywall T-square, squareness is non-negotiable. The head must hold a square shape to maintain accurate angles. Clear and easy-to-read gradations are also essential for precise measurements.
    • Graduation Marks: Easy-to-read graduation marks and stud markings at standard intervals (such as 16 inches on center) can significantly ease the measurement and layout process​​.
