When framing a rough opening for a door using metal studs, how much wider should the rough opening be than the door?

When framing a rough opening for a door using metal studs, the rough opening should be wider than the actual door to accommodate several important factors. The correct width of 2-1/2 to 3-1/2 inches allows sufficient space for the door itself as well as provides room for the door frame, shimming, and proper installation.

Having extra width is essential for ensuring that the door has enough clearance for proper operation, especially to account for any variations in the wall or framing. It also allows for the installation of door hardware, such as hinges and locks, without interference. Additionally, the extra space aids in adjusting the door during installation to ensure it hangs correctly and operates smoothly.

This amount of space is a standard industry practice that balances practicality with efficiency, providing the necessary margin for adjustments while not making the rough opening excessively large, which could lead to structural issues or inefficient use of materials.
