A:Answer Hello, for model WSR57R18DM, Allow at least a 3” (7.5 cm) clearance on both sides of the
Refrigerator and 2” (5 cm) between the back of the Refrigerator and the wall. If the freezer is to be next to a fixed wall, leave extra space on the hinge side so the door can open wider. Thank you for your inquiry on our Whirlpool appliances.
