    How can I automatically create a rectangular layer mask from an irregularly shaped selection?

      I am trying to automatically crop images. The subject is on a white background and extends from the left edge of the image to the right. The top and bottom of the subject are within the frame. I need to crop a certain distance from the top and bottom of the subject and a predefined width that would be calculated from the height of the subject.

       

      My current idea is to create a duplicate layer and run Threshold on it, which allows me to select the subject clearly. Once I have the subject selected I can use Image -> Crop to create the desired rectangle, but I can't figure out a way to create a mask from the irregularly selected subject. Does anyone know a way to take a selection and convert it to a rectangle? I hope this makes sense, I can try to explain better if not. Thanks.
