A:Answer The base stand attaches to the center of the TV in the shape of an upside-down Y. The width of the Y is approximately 45 inches. The depth is approximately 18 inches from where it mounts at the base of the TV. If it's going to sit on a TV stand of some sort, the top of the stand needs to have a measurement of at least 18 inches deep and 48 inches wide, but the TV is 66 inches wide and would look strange on a 48 inch TV stand. A 60 inch wide TV stand would look better to sit the TV on . I didn't use the stand. I mounted mine on the wall with multi-positioning wall mount. P.S. Amazing picture!
