Refrigerators come in a variety of shapes, sizes, and colors. Did you know, for example, that it's important to measure your existing space before purchasing a refrigerator? You should also think carefully about what you need in your refrigerator. Do you need a big freezer, or do you prefer a freestanding freezer and more space in the refrigerator itself? What style do you prefer: side by side, or with the freezer on top as in more traditional models?
