It depends on the type, size, and dimensions of the room where you will hang your chandelier, but the average and ideal distance from the floor should be 8 or 9 feet (245 or 275 cm). For the best safety, elegancy, and illumination functioning, you should hang it higher than 7 feet (215 cm) above the floor in the middle of the room or entrance. In terms of other elements like the dining table, you should hang it 4 feet (120 cm) over the dining table.
