Interior doors can become damaged, difficult to operate or old-fashioned compared to the rest of the décor. Replacing an interior door is a one-day project for one or two people.
Step 1: Measure for replacement door Use a tape measure to find and record the measurements of both the door opening that the frame fits into and the door itself. Door sizes are listed by width first and length second. When purchasing a pre-hung door, note the configuration of the old door. If the door opens toward you and the door knob is on the left, it is a left-handed door. If the door opens toward you and the door knob is on the right, it is a right-handed door. To get accurate measurements of the door frame, complete step #2 first. Measure the width of the existing door.
