The refrigerator capacity needed for two people can vary depending on their eating habits and lifestyle. As a general guideline, a refrigerator with a capacity of about 200 to 300 liters should be sufficient for most two-person households. Therefore, if your refrigerator is smaller, it can be very interesting to purchase an additional refrigerator, such as a smaller tabletop model. However, it is important to consider individual preferences and the amount of perishable food and beverages to be stored.
