A pendant light over the dining table is one of the few lamps at home that we look at up close every day—and one of the most often hung incorrectly.

In this guide you’ll find specific dimensions: how high to hang a pendant over the table, how to match its diameter to the tabletop size, and how many pendants to hang over a rectangular table.
