Cabinet hinge overlay refers to the amount the cabinet door extends over the cabinet frame or face when closed. This measurement is critical for ensuring proper door alignment, function, and aesthetic appeal. It is expressed as a numerical value, often in inches or millimeters, and represents the distance from the edge of the door to the edge of the cabinet frame. For example, a half-inch overlay signifies that the door extends half an inch beyond the frame.
Accurate determination of the overlay is essential for selecting the correct type of hinge. Using the wrong hinge can result in doors that bind, don’t close properly, or appear misaligned. Historically, cabinetmakers relied on experience and visual estimation; however, precise measuring tools and understanding of overlay principles allow for consistent, professional results. Correct overlay measurement contributes to a clean, finished cabinet installation, improving both its functionality and visual presentation.
