What is the vertical distance required between screws on gypsum board framed 24 inches on center?

10 inches
12 inches
14 inches
16 inches

The correct answer is: 12 inches

The correct vertical distance required between screws on gypsum board that is framed 24 inches on center is 12 inches. This requirement is established by building codes and best practices for drywall installation, ensuring that the gypsum board is securely fastened and minimizes the risk of sagging or other structural failures. When installing gypsum board, it is essential to follow these spacing guidelines to achieve optimal strength and durability. The 12-inch spacing helps to prevent the board from bowing between supports, especially on walls that may encounter higher levels of stress or movement. By maintaining this spacing, the installation enhances the overall integrity of the wall surface and provides a stable base for further finishing processes, such as taping and mudding. This guideline is also supported by manufacturers' specifications, reinforcing its importance for achieving satisfactory results in construction practices related to drywall installation. Awareness of and adherence to these standards can significantly improve the quality and longevity of the finished project.
