There's something inherently pleasing about things that match – from matching pillows on a couch to matching paintings on either side of a room. These elements create a sense of cohesion, balance, and order, all thanks to the rule of symmetry.
As one of the most basic but most important principles of interior design, symmetry is the act of arranging the same or similar elements to mirror or match each other in a room, creating a sense of harmony in the space. Often, people introduce symmetry in design without even realizing it – simply because it feels natural and satisfying to the eye.
