A TV stand should generally be at least as wide as the TV that you’re placing on top of it, and you should always check to see what size TV the stand is compatible with. “A good rule of thumb is to have a few inches on each side of the TV to add some photos or decor pieces,” says Day. “Something that is also very important to consider is the height of all your pieces. For instance, if your couch sits lower to the ground, then you don’t want to opt for a tall TV stand. Be sure to measure before investing in a TV stand.”
