The ideal coffee table is two-thirds the width of your sofa. If you have a sectional with a chaise, then the table should be two-thirds the size of the sofa portion only. This creates a balanced look in the room.
What is a standard coffee table?
The average size of a coffee table is between 36-48 inches in length and 18-24 inches in width. Or just keep in mind that the average size of a coffee table should not be more than 2/3 of the length of your couch (whatever the dimensions of your couch might be).
How big is too big for a coffee table?
Specifically, your coffee table should be approximately two-thirds the length of your sofa. So for a 96-inch sofa, for instance, you should look for a coffee table that’s 64 inches long.
