How to figure out what size TV you should buy

TVs aren’t one-size-fits-all. Far from it, in fact. Every room has its own Goldilocks zone, with several factors — how far from the screen you’re going to be sitting and whether you’re going to mount the television on the wall, for example — coming together to determine the ideal screen size. So, how do you figure out which TV size you should buy? Just use our interactive guide (below) and follow our expert advice.

Will it fit in your TV room?

Before you start shopping, you’ll need to decide where you want your television to reside. Once you’ve chosen the location, measure the height, width, and depth of that spot (there may be limitations due to the size of an entertainment center or amount of space on a wall). Later, when shopping, you can match this up with the measurements of the television itself, not its screen size, to make sure it will fit. You’ll find some TVs have footprints that are physically larger than others of the same screen size, so always look at the dimensions to see whether it will slot into the space available.

How wide is the stand?

The second size-related consideration is the television’s attached stand. If you aren’t going to mount your television on a wall, this will play a big part in how much space it takes up on your console table, and many newer TVs have feet at the far edges. You need to ensure that wherever you plan on placing the television is wide enough to accommodate the stand. You’ll want to be strict here, too. Often, people think it’s safe to let the corners overhang, forgetting that it’s been designed to rest on a flat surface. Fail to do so and the faintest breath of wind could send the whole thing tumbling over.

How far away will you be?

Next, think about where you’ll be sitting in relation to the TV. There are viewing distance calculators (here is another calculator) that recommend a screen size based on where you sit. If you don’t want to bother with an online calculator, there’s a simplified calculation that you can do to work it out yourself: Measure the distance from your seat to the television in inches and multiply by 0.84. This should give you the ideal screen size.

This method isn’t perfect, of course. For instance, if you are sitting 8 feet from the TV, the calculation calls for an 80-inch screen, and that’s just not realistic for most of us. Most living rooms will do best with at least a 50-inch screen size and, of course, taste and style are going to factor in heavily. You can technically go as big as you like — make sure you’re sitting more than 4 feet from the television itself and you should get on just fine.

Size vs. quality

If you’re trying to maximize screen real estate on a tight budget, you’re going to have to sacrifice picture quality. As such, we’d recommend — as per our comprehensive TV buying guide — striking a balance between the two factors for long-time enjoyment. So instead of going for that massive 65-inch 4K TV from an up-and-coming brand that’s on the shelves for just $500, consider opting for the smaller 55-inch, big-name model next to it for $550. Chances are, it has a far better screen, and that’ll result in a much more immersive viewing experience, even more so when using HDR.
