It depends on how high and long you want it. Generally the sofa table is behind the sofa near the top of the sofa. However, if you don't want too much showing over the sofa you would want one lower towards the middle of the sofa.
To measure the length of a sofa, you can use either inches or feet, depending on the level of precision you desire. Inches provide a more detailed measurement, which can be useful for fitting the sofa into a specific space. Feet may be more convenient for general measurements, especially in larger living areas. Ultimately, both units are acceptable, but inches are often preferred for furniture measurements.
There is no such unit of measurement as a sofa.
The length of a typical living room sofa ranges from 76 to 92 inches. A typical living room sofa should be able to seat at least three people comfortably. The length of the sofa should be determined by the size of the living room, the sizes of the other pieces in the room and ones personal preferences.
The standard coffee table length is actually one-half to two-thirds the length of the sofa it will rest before.
