What is the standard depth of base cabinets in construction?

Base cabinets in construction typically have a standard depth of 2 feet (24 inches). This dimension is designed to provide ample space for storage and to accommodate standard kitchen counter heights and appliance sizes. The depth allows for easy access to items stored within the cabinets while also ensuring that countertops, which usually extend beyond the cabinets, can be used effectively.

The other options do not align with standard practices in cabinetry design. A 1-foot depth would be too shallow for most uses, leading to inefficiency in storage and usability. Similarly, a 3-foot or 4-foot depth would be impractical, consuming unnecessary space and making it difficult to reach items stored at the back of the cabinets. Therefore, a standard depth of 2 feet strikes a balance between storage capacity and accessibility, making it the preferred choice in residential and commercial settings alike.
