Where doors have but two panels in width, let the stiles and muntins be each 1/7 of the width; or, whatever number of panels there may be, let the united widths of the stiles and the muntins, or the whole width of the solid, be equal to 3/7 of the width of the door. Thus: in a door 35 inches wide, containing two panels in width, the stiles should be 5 inches wide; and in a door 3 feet 6 inches wide, the stiles should be 6 inches. If a door 3 feet 6 inches wide is to have 3 panels in width, the stiles and muntins should be each 4 1/2 inches wide, each panel being 8 inches. The bottom rail and the lock-rail ought to be each equal in width to 1/10 of the height of the door; and the top rail, and all others, of the same width as the stiles. The moulding on the panel should be equal in width to 1/4 of the width of the stile.
