Of course, you may think you know the size of the TV you buy on Amazon or Best Buy's website, but what if you're wrong? TV formats are measured diagonally, so it may come as a surprise how much larger a 65-inch TV is than a 55-inch TV. And two different 66-inch TVs can have different width and height. Sony's AR app aims to help you check your fit, at least for Sony TVs.
The app, which runs on Android and iOS, is fairly intuitive. Choose your Sony TV model, the format you want it in, then point your camera where you want the TV. The app overlaps a cabinet on your wall or TV stand to give you an idea of how much space it needs.
Of course you need a recent smartphone ̵
If you still want to buy a Sony TV, you can download the Envision TV Ar app on iOS or Android to see if it suits your living room now.
