We are a family of 7. My mom purchased 4 of these 100 cup ingredient bins. Fits about a 50lb bag of rice, 25 pounds of flour, and about 50lb of sugar. They come with a divider that helps rotate ingredients. The new sits higher and drops down as the old is used. After trying everything from 5 gallon buckets to fancy ingredient bins that almost looked like trash cans from simple human and difficult to open, these were the best purchase. Items are not kept airtight, so if you are wanting something airtight then these are not for you. With our family size and the amount of baking we do these are perfect. Ingredients are easily accessible, this slides under our work table with ease and they can be stacked. There are also 40 cup bins just like these for smaller families. I can also see this working for pet food, but because I can imagine a dog figuring out how to open it, it should be kept away from the pets.
