What Does Cubic Feet Mean?
Cubic feet measure the interior storage volume of the refrigerator.
Manufacturers calculate refrigerator capacity based on the usable space inside the:
- Fresh food compartment
- Freezer compartment
The measurement does not refer to the refrigerator’s exterior dimensions.
How Refrigerator Capacity Is Calculated
Refrigerator capacity is measured by multiplying the interior:
- Length
- Width
- Height
The result gives the volume in cubic feet.
Manufacturers perform these calculations using standardized testing methods to determine official storage capacity.

| 1 person | 10–12 cu ft |
| 2 people | 12–18 cu ft |
| 3–4 people | 18–22 cu ft |
