Configurations
Although a two-door, top-mount refrigerator-freezer unit is the most affordable option, bottom-freezer units are growing in popularity because they put fresh food at eye level. Side-by-side models have narrow doors that open at the center. They generally offer more overall storage capacity and easier access for children or people in wheelchairs. However, most of these units have an in-door icemaker on the freezer side, which limits freezer space. The latest refrigerator-freezer variation—typically referred to as a French door refrigerator—combines the easy access of a side-by-side model with the practicality of a bottom-mount freezer drawer.

Space Requirements
Refrigerator dimensions vary greatly. Measure the height, width, and depth of your available space and bring these dimensions when you shop. Shallow models that extend about as far as standard countertops look better than those that bump out and block traffic or a doorway.

Capacity
Refrigerators range from 9 to 30 cubic feet. A family of two generally needs 8–10 cubic feet of fresh food space. Add an extra cubic foot for each additional family member. A family of two needs about 4 cubic feet of freezer space. Add 2 cubic feet for each additional person. Increase the freezer space if you buy a lot of frozen products or shop infrequently. Refrigerators can operate for 15 years or more, so remember to plan for changes in family size. Top- and bottom-mount freezers offer the most storage flexibility. Side-by-side models may offer more space, but sometimes it’s tricky to wedge in a pizza or other large item.

Features
Icemakers are available in the freezer or in the door. Adjustable-height glass shelves make room for items of any size and make things easier to find. Spillproof shelves reduce cleanup time; they should lift all the way out for washing in the sink. Also look for large, adjustable door bins and spacious crispers with clear fronts. Adjustable humidity controls keep foods fresh longer. In the freezer, slide- and tilt-out baskets are handy.

Noise and Energy Issues
When you’re in the store, ask that a few models be turned on so you can hear how they sound. The noise will be quieter in your kitchen than on a concrete sales floor. Check each model’s yellow Energy Guide label to determine the average energy use per year. Make sure the models you compare are the same capacity.
