Common Questions
Refrigerator Buying FAQ
How much refrigerator space do I need per person?
A general rule is 4–6 cubic feet per adult. Meal preppers and bulk buyers should add 2–3 extra cubic feet. Teenagers need significantly more than adults — factor 5–6 cubic feet per teenager. People who eat out frequently can go on the lower end of 3–4 cubic feet per person.
What's the most important measurement before buying?
Width is usually the tightest constraint. Measure the opening at the narrowest point and subtract 1 inch on each side for clearance. Also measure the path the fridge needs to travel — doorways, hallways, and stairwells are commonly overlooked. Depth matters too: standard fridges stick out 6–8 inches beyond counters, while counter-depth models sit flush but sacrifice 2–4 cubic feet of storage.
French door vs side-by-side — which is better?
French door puts fresh food at eye level — since most people access fresh food 8–10x more than frozen, this is the most ergonomic choice. Side-by-side gives you full-height access to both sections simultaneously and is the easiest style to fit an external ice and water dispenser on narrower kitchens.
Is counter-depth worth the extra cost?
Counter-depth fridges cost $300–$800 more and sacrifice roughly 3–5 cubic feet. If your kitchen is tight or you want a built-in look, it is absolutely worth it. If storage capacity is your priority, standard depth gives you significantly more space for your money.
How much does a refrigerator cost to run per year?
A modern Energy Star fridge typically costs $30–$80 per year depending on size and local electricity rates. Older models from 10+ years ago often cost 2–3x more. Always check the EnergyGuide label before buying — a $50/year difference adds up to $500 over 10 years.
Top freezer vs bottom freezer — does it matter?
Top freezer is the most affordable and energy efficient style, but fresh food sits at mid-to-low height so you bend frequently. Bottom freezer puts fresh food at eye level with the freezer as a pull-out drawer — much more ergonomic for daily use. Most people prefer bottom freezer once they have used one, despite the $100–$300 price premium.
What clearance does a refrigerator need?
Leave at least 1 inch on each side, 1 inch at the back, and ½ inch at the top for airflow. Inadequate clearance forces the compressor to work harder, raising energy bills and shortening lifespan. For door swing, allow the full door width plus 2–3 inches to comfortably open drawers.
