How many shims does it take to install a door?

The number of shims needed to install a door can vary depending on the specific situation, such as the door frame's level and plumbness. Typically, 2 to 4 shims are used on each side of the door frame, placed at the top, middle, and bottom to ensure proper alignment and support. It's essential to adjust the shims as needed to achieve a level and functional installation.
