Freestanding side-by-side refrigerators are typically between 30 and 36 inches wide and between 67 and 70 inches tall. The depths of these refrigerators range from 29 to 35 inches. Built-in refrigerators don't have standard sizes, and their widths range from 24 to 48 inches.
Cabinet-depth refrigerators have the same width as standard units, but they are only 24 inches deep, bringing them flush with surrounding cabinets. Once the refrigerator is in place, it should have 1 inch of space on each side to allow for proper air flow. A refrigerator's height is listed with or without the front hinges because these hardware pieces can interfere with full-depth upper cabinets.
