Standard kitchen cabinets typically have a depth of 24 inches (61 cm). This depth allows for the installation of standard countertop materials, such as granite or laminate, which are typically 1.5 inches (3.8 cm) thick. The remaining space accommodates the cabinet box, doors, and drawer fronts.
However, it's worth noting that there can be variations in cabinet depths depending on specific design choices or customizations. In some cases, cabinets can have a reduced depth of 12 to 18 inches (30 to 46 cm) in areas where space is limited, such as above appliances or in narrow galley kitchens.
It's important to measure the available space in your kitchen and consider the specific cabinet designs you're interested in to determine the most suitable depth for your cabinets. Additionally, if you plan to install appliances or incorporate specialized storage solutions, such as pull-out shelves or corner cabinets, those factors may also affect the depth of the cabinets you choose.
