Free refrigerator size calculator determines optimal capacity (10-36 cu ft) based on household size, cooking frequency, and shopping habits. Get personalized recommendations with our AHAM-compliant sizing tool.
Based on AHAM 4 cu ft per primary occupant, plus household-level adjustments.
Reference numbers come from the Association of Home Appliance Manufacturers' household sizing guidance, with every adjustment stated on this page and in our published methodology.
AHAM recommends a 4 cu ft base for the primary occupant, plus 2–3 cu ft for each additional person.
+2 cu ft for weekly cooking, +4 for daily cooking. +3/+6/+10 for weekly, biweekly, and monthly shopping.
<20 cu ft → top-freezer. 20–25 → French door / side-by-side. 25–30 → large French door. 30+ → counter-style.
