Glad you asked! Our guide to light sizing includes information about this very topic.

For over a table, look for chandeliers that are between 2/3 and 3/4 of the table's diameter. Then, hang it between 30 to 36 inches above the table.

So, if your table is 60" in diameter, you could look for chandeliers between 40" and 45" in diameter.

Let me know if you have any questions or want to look at some chandeliers!
