How can lines be used to make a large room appear small?

Lines can be used to make a large room appear smaller by creating visual boundaries and dividing the space into smaller, more intimate areas. This can be achieved through the use of vertical lines, such as tall bookcases or curtains, to break up the height of the room and create a cozier atmosphere. Horizontal lines, such as a low-hanging ceiling or a long, low-slung sofa, can also be used to visually shorten the length of the room and make it feel more enclosed. Additionally, using patterns with strong lines, such as stripes or geometric shapes, can create a sense of movement and depth that can help to visually shrink the size of the room.
