The fridge-freezer ratio depends on the model that you have bought. In single-door fridges, the ratio can be as low as 20:80. But, bigger fridges and multi-door refrigerators can vary between 60:40, 50:50, or 70:30. The ratio is generally higher in the case of side-by-side refrigerators. If you want more personalization, opt for convertible fridges where the ratio can be altered.
