Frame-and-panel doors
AKA rail-and-stile doors
Frame-and-panel doors
Frame-and-panel doors use a form of construction in which large floating panels are held within a framework of horizontal rails and vertical stiles. Also called rail-and-stile doors, the advantage of this construction style is that the floating interior panels can shrink and expand with the weather without seriously affecting the overall fit of the door within a cabinet or passageway. Such doors are much less likely to warp or crack.
Stiles: The stiles are the left and right vertical frame members of the door. They run the full length of the door, from top to bottom, and provide the principal structural strength of the door.
Rails The rails are the horizontal frame members of the door. They butt into the stiles using mortise-and-tenon joints. A classic six-panel door includes three rails: the top rail, the middle rail (called the lock rail), and the bottom rail.
Mullions: Mullions can be described as the shorter inner stiles that span the gap between horizontal rails. The mullions separate the pairs of floating panels.
Panels: These are the large flat areas of the door that float within the spaces created by the frame members. The panels of a classic six-panel door are usually three pairs of different sizes. For visual balance, the largest panels tend to be in the middle, with the smaller panels at the top and the bottom.
Advantages of Frame-and-Panel Construction
Structural stability: The frame-and-panel construction provides stability to a wooden door, allowing the large floating panels contained within the framework to expand and contract with changes in humidity. The floating construction prevents cracking and splitting.Stylistic flexibility: Frames and panels can be arranged in various fashions to maintain consistency with different architectural styles. While the classic six-panel design described here telegraphs a colonial home style, other door styles signify styles such as Craftsman bungalows (six horizontal panels of the same size), Victorian (four panels, paired as two longer upper panels and two shorter lower panels), modern (two relatively large panels), or Arts-and-Crafts (one large upper panel with two narrow lower vertical panels).
So popular is this style that flat slab doors are sometimes dressed up with added moldings nailed or glued onto the slab to make them look like panel doors—much the way that "faux" wainscotting can be created on flat walls.

There are many styles of frame-and-panel door, but one of the most common is the so-called classic six-panel door, which features two smaller upper panels, two long center panels, and two intermediate-sized lower panels. Although this door style is architecturally most appropriate to colonial-style architecture, it is so popular that it is often used (or misused, in the opinion of purists) in homes of entirely different architectural styles.
The classic six-panel door is sometimes known as a cross-and-bible door, due to the apparent symbolism found in the door shape. It does not take too much imagination to see the shape of a Christian cross in the arrangement of the top mullions and intersecting cross rail, and only a slightly bigger leap of imagination to see the bottom two panels as forming the shape of an open book. However, most experts consider this name to be irrelevant to the actual development of the door style, since similar doors are found in older Jewish architectural traditions as well as other non-Christian traditions. More likely, this door style is so popular because it is one of the sturdiest and most durable variations of the frame-and-panel style.
