The minimum width we will manufacture a cabinet door is 6 inches for flat-panel cabinet doors and 8 inches for raised-panel cabinet doors. The maximum height we will manufacture cabinet doors is 60 inches. The maximum width is 24 inches. A crosspiece is added to all doors over 42 inches in height (double panel door). On doors over 36 inches tall, a warpage of less than ⅛ inch is within tolerances.
