Chandeliers for the living room

A 4 × 5 m living room takes a chandelier of about 75 cm across. Add the room’s length and width in metres and multiply by eight — the answer is the diameter in centimetres.

Under a standard 2.7 m ceiling the whole fitting wants to be 57 to 69 cm tall. Over a coffee table it can hang lower; over anywhere people walk, never below 2.1 m.
