How do I know which sill pan fits my door or window?

For swinging doors and wood windows measure the jamb width. For sliding doors and vinyl windows measure from the nail fin back to the interior edge of the door/window frame. If you are installing an out-swing door make sure the jamb dimension is the same as the wall thickness. Sometimes a 4 9/16″ jamb out-swing door is used in a 6 9/16″ wall.
