What type of door consists of stiles, rails, and panels?

• A. Panel
• B. Flush
• C. French
• D. Barn

Answer: (A)

Panel doors use a frame-and-panel construction: vertical stiles on the sides and horizontal rails at the top and bottom (and sometimes a middle rail) create a rigid frame, and one or more panels fit inside that frame. This design lets each panel move slightly with wood expansion and contraction while the frame stays stable, which is why you’ll hear it described as frame-and-panel construction. The look comes from the panels filling the openings between the rails and stiles, giving the door its characteristic segmented appearance.

Flush doors, by contrast, are solid and flat with no separate panels inside a frame. French doors are hinged units that feature multiple glass panes within a frame. Barn doors are typically built from boards and slide on a track, not from a framed panel inside a frame.
