How to frame a pocket door
Determine whether or not the wall you've chosen for pocket door installation is a good candidate.
The wall needs to be wide enough to accommodate twice the door's width, plus 1 inch (2.54 cm). You'll also need to know whether or not the wall is load-bearing.
You can determine this by the wall's placement in the house. Generally, load-bearing walls will be in a central location, and they will be perpendicular to the floor joists.
