Many psychotherapists believe that the nuances of psychotherapy cannot be captured by questionnaire-style observation, and prefer to rely on their own clinical experiences and conceptual arguments to support the type of treatment they practice.
Recommendation: The clear opening of a doorway should be at least 32. This would require a minimum 34 or 2'-10 door. For universal design, the minimum clear width is 34. If the existing structure precludes changing the opening then a minimum 24 or 2'-0 door is allowable. The door opening width is measured from jamb to jamb.
Determine the size of a single door or pair of double doors that suits your purposes. Standard door widths range from 24 inches to 32 inches. Double the width of the desired door, or pair of doors, to determine the wall space that's needed to install the pocket door frame. For example, 48 inches is needed to install the frame for a 24-inch door. For double doors, double the width of one door and multiply the result by two.
