Determining the Required Door Panel Size for Sliding Doors The door panel needs to be slightly wider than the door opening. The door will be mounted about 1/2" to 1" above the floor level, so the door panel can be the same height as the door height opening. Here are some guidelines on measuring.
Determine the minimum door width:
To determine the minimum door width, measure the distance between the inside frame opening and add 2” to each side (A + 2” + 2” = minimum door width ). This will allow the door to cover the frame opening when the door is fully closed.
A
Determine the minimum door height:
To determine the minimum door height, measure between the finished floor and the frame, then subtract ½” for floor clearance from the bot - tom of the door (B - 1/2” = minimum door height ). Door may cover the top trim if desired.

Check for minimum door clearance:
C
A minimum clearance of 6½” (C) is required from the top of the door to the ceiling, to accommodate the track and sliding hardware. The top of the door should be level or above the frame opening. A minimum clearance of available wall space equal to the actual door width is required (D) for the door to completely roll free of the door opening.
