TV wall mounts

A good mount puts the screen at the right height and lets you angle it away from glare. Match the mount's VESA pattern and weight rating to your TV, and use full-motion arms for wide or off-center rooms.

Frequently asked questions

Is a 75 inch TV much bigger than a 65 inch?

Yes. Diagonally it's 10” larger, but because screen area grows with the square of the diagonal, the 75” picture is about 33% bigger (1.33× the area) than the 65”. Side by side the difference is very noticeable.

How much farther should I sit from a 75 inch than a 65 inch TV?

For the same immersive THX view, plan about 6.5 ft for the 65” and 7.5 ft for the 75” — roughly 1 ft more.

Should I buy the 65 or the 75 inch TV?

If your seat is around 8.7–6.5 ft away, the 65” is comfortable; from 10 ft or more, step up to the 75”. When in doubt and the budget allows, most people prefer the larger screen — very few wish they'd bought smaller.

Will a 75 inch TV fit where a 65 inch was?

The 75” picture is about 65.4” wide vs 56.7” for the 65” — roughly 8.7” wider. Check your stand width and any recess before upgrading.
