In Sims 4, there are a lot of different ways to size things up. You can choose to have things be either small or large. You can also choose how much space each object takes up in your home. There are also a lot of different objects that you can place in your home, and they all have different sizes. One way to size things up is to use the sizing tool. This is located in the bottom right corner of the game window, and it will let you choose between small, medium, or large. Once you have chosen a size, it will let you know how much space each object takes up in your home. You can also use the placement tool to place objects in your home. This is located in the top left corner of the game window, and it will let you choose between placing them on top of other objects, on the side of other objects, or inside other objects. Once you have chosen an object placement option, it will let you know how many spaces are needed for that object to fit into your home.
