Refrigerator Size Calculator
What size fridge does your household actually need?
About 23 cu. ft. (20–28) for a family of four that cooks daily and shops weekly, per the Fridge.com size calculator. Estimate refrigerator capacity from household size, cooking frequency and grocery shopping habits. See the formula, capacity range and suggested styles.
Three inputs.
One real answer.
Start with 4 cu ft per person, then add the cooking and shopping allowances below.

How the estimate is calculated.
This Fridge.com planning formula uses the three inputs above. It estimates capacity; it does not measure your food storage or verify that a refrigerator fits your kitchen.
- 01
Base capacity per person
Start with 4 cu ft for each person in the household.
- 02
Cooking & shopping adjustment
+2 cu ft for weekly cooking, +4 for daily cooking. +3/+6/+10 for weekly, biweekly, and monthly shopping.
- 03
Style recommendation
Below 20 cu ft: compact or top-freezer. 20 to under 25: French door or side-by-side. 25 to under 30: large French door. 30 or more: extra-large styles.
Know your cutout? Shop refrigerators by recorded width.
Every collection lists the models we track at that recorded width with the lowest tracked price on each. The median full-size refrigerator records 33.13 inches wide, and one in three will not clear a 30-inch doorway on either side.
