The ideal sofa table length is about two-thirds the length of your sofa — so for an 84-inch couch, look for a table around 56 inches long. That’ll give you enough room for décor without overwhelming your setup. 

Technically, yes — no furniture police here. But practically, it’s best if the table is just under or level with the back of your couch. That way, it doesn’t peek over or distract from your sofa’s style. 

Just a few inches. Too much space looks awkward and can turn into a shin-bumping hazard. But don’t press the table directly against the sofa either — a little wiggle room keeps things from getting knocked over when the couch gets rowdy (looking at you, zoomie-prone pets).
