The most common thickness of cabinet doors in America is typically 3/4 inch (19 mm). This thickness is widely used in both kitchen and bathroom cabinets. It strikes a balance between sturdiness and weight, providing durability while still being relatively easy to handle and install.
Cabinet doors with a 3/4-inch thickness are sturdy enough to withstand everyday use and provide structural integrity to the cabinet. They are also compatible with a wide range of hardware options, such as hinges, knobs, and pulls.
While 3/4 inch is the standard thickness for most cabinet doors, there are variations available, such as thinner doors at 5/8 inch (16 mm) or thicker doors at 7/8 inch (22 mm), depending on the manufacturer and customization options. However, the 3/4-inch thickness remains the most commonly used and widely available option in the United States.
