how deep are upper kitchen cabinets

Upper kitchen cabinets are generally 12 inches deep, which is the most common standard depth to provide adequate storage without protruding too far over the countertop. However, their depth can vary somewhat, typically ranging from 12 to 15 inches, and in some cases, upper cabinets can be as deep as 24 inches, especially when placed over appliances like refrigerators for easier access. In metric units, this standard depth is about 30 cm. Deeper upper cabinets (up to 20 inches or 50-56 cm) are sometimes used for more storage or for aesthetic matching with base cabinets but are less common in typical kitchen layouts where space and usability over the countertop are priorities. Thus, for standard kitchens, expect upper cabinets to be about 12 inches (30 cm) deep as the typical measure.
