Symmetry in interior design means arranging elements so they mirror each other around a central line: two matching lamps on either side of a bed, a sofa centred on a fireplace with an armchair on each side.
Types of balance
- Symmetrical (formal) balance: mirror images on both sides of an axis. Calm, orderly, classic; typical of traditional rooms.
- Asymmetrical (informal) balance: different objects of similar visual weight on each side, for example a tall plant on one side of a sofa and two stacked side tables on the other. Relaxed and modern.
- Radial balance: elements arranged around a centre, like chairs around a round table or a chandelier at the centre of a ceiling.
Using it
- Symmetry is the quickest way to make a bedroom or living room feel ordered: start with matching pairs at the anchor piece.
- Break it slightly (different art, one plant) to avoid a showroom look.
- In open-plan spaces, use symmetry within a zone rather than across the whole room.
