Refrigerator Size Calculator
Fridge cubic feet and fresh/freezer split for any household.
What it does
Fridge size follows mouths. Too small and groceries stack past the light, too big and energy cools empty shelves all year.
The tool above adds a base plus per person space. Four people suit 22 ft3 total with 15.4 fresh and 6.6 freezer on a standard split. The metric match is 623 L with 436 fresh and 187 freezer.
The 4 per person rule fits weekly shoppers. Daily fresh buyers run smaller, bulk clubs run larger, and hunters need a separate freezer anyway.
Splits follow doors. Standard tops hold 70 % fresh, french doors trade 5 % to the freezer drawer for wide shelves.
Tape measures close the sale. Door swings, hall turns, and counter depths veto many perfect sizes.

Worked example
Example: family of 4

- Split: standard 70 % fresh.
- Fresh: 22 x 0.70 = 15.4 ft3.
- Freezer: 22 - 15.4 = 6.6 ft3.
- Tool shows 22 ft3 total, 15.4 ft3 fresh, 6.6 ft3 freezer.
