Freezer capacity,
in cubic feet.
Measure the interior of your freezer, fridge, or chest freezer. Get the true capacity in cubic feet and liters — and an estimate of how much food it actually holds.
Packed food capacity uses the usual planning rule of 35–40 lb of packaged food per cubic foot. Bulky or awkward items — a whole turkey, a side of beef — pack less efficiently, so treat the lower end as the realistic figure. This is interior box volume; shelves, baskets and the compressor hump take some of it back.
What size do you need?
Rule of thumb: 1.5 cubic feet of freezer per person for general household use. For dedicated meat storage, harvest preservation, or batch cooking, plan for more.
- 1 person: 5 ft³ — a small upright or chest
- 2 people: 5–7 ft³ — apartment freezer
- Family of 4: 7–10 ft³ — mid-size chest freezer
- Family of 6: 12–15 ft³ — large chest or upright
- Hunters / homesteaders: 15–25 ft³ dedicated
Chest freezers are usually 10–20% more efficient than uprights and store food longer during power outages. Uprights are easier to organize.
| 1 cubic foot | 35–40 lb food |
| 5 ft³ freezer | 175–200 lb |
| 7 ft³ freezer | 245–280 lb |
| 10 ft³ freezer | 350–400 lb |
| 15 ft³ freezer | 525–600 lb |
Whole birds and large cuts pack less efficiently — figure 75% of these numbers.
