11 of the 12 Sony 65" models from 2024 to 2026 use 300 × 300 mm. The others use 400 × 200 (1). 6 of them weigh more than this one. At 49.2 lb it is close to the 47 lb typical of 65" panels.
Sony does not list the screw size for this model. Most TVs use M6 or M8; try the screws in the bracket's kit by hand before tightening anything.
The holes are 11.8" apart side to side; the wall plate of the bracket, not the TV, has to reach the studs.
