Fridges for 3 to 4 people have a cooling compartment of 150 to 250 liters. This gives you enough space to do your weekly groceries. Some fridges also have a freezer compartment. When buying a new fridge for 3 to 4 people, choose a fridge freezer combination, compact fridge, or a 1-door standard fridge. You can choose between a freestanding or a built-in fridge. When buying a built-in fridge, pay attention to the niche dimensions and if the fridge has a door-on-door or a slider door system.
