How do I know a mount will fit my TV?

Check two numbers: your TV's weight and its VESA hole pattern (the spacing of the four mounting holes on the back). Most picks here cover VESA patterns up to 600x400mm and weights of 120–132 lbs, with one heavy-duty fixed option rated far higher. Reviewers note that screen size ranges printed on the box are approximate — the weight and VESA figures are what actually matter.
