Top-freezers offer the most storage for their size and are the least expensive. Top-scoring refrigerators usually deliver more consistent temperatures.

Bottom-freezers keep refrigerator items within easy reach. Most models we tested chill and freeze adequately and include pullout shelves or bins, split shelves, spill guards, and room in the door to hold a gallon of milk.

Side-by-sides are ideal for narrow kitchens but are the least space-efficient inside. Higher-end models offer half shelves. And if your household isn't large, remember that a smaller refrigerator is likely to use less electricity overall than a larger model.

Built-ins align with cabinets. Most models we tested chill and freeze adequately and include pullout shelves or bins, spill guards, and room in the door for a gallon of milk. Top-scoring models usually deliver more consistent temperatures.
