The 82 inch QLED has 2 positions for the legs. The wider position is 61 inches apart. The other position is 46.5 inches apart. Keep in my mind that the egs do have a depth (leg span from front to back) of 15.5 inches so ideally your cabinet should be wider that 56 inches for the narrow 1st position, wider than 70 inches for the wider 2nd position with a depth of at least 16 inches.
