How to Measure the Right TV Screen Size for Your Room?

Choosing the correct screen size for your TV is more than just a case of bigger is better. If you sit too near to a large screen, you will have eye strain or simply not be able to view the entire picture. It's critical to buy a TV that's the correct size for your room. In this article, we will guide you on choosing a TV size that is suitable for your demands.

How to Measure the Right TV Screen Size for Your Room?

The Society of Motion Picture and Television Engineers (SMPTE) recommends that your TV occupy at least a 30-degree arc in your field of vision. Meanwhile, THX suggests a 40-degree angle for a cinematic viewing experience. However, all of these measures are based on a 1080p resolution. You should be able to reach even closer to a 40-degree viewing angle with a 4K screen.

If your sofa is six to seven feet from where you intend to install your TV, a screen of up to 55 inches should suffice. You may safely go up to 65 inches if your sofa is seven to eight feet away.

There is some wriggle space here. Going a little bigger or smaller will not damage your viewing experience, and you should always prioritize your comfort level over any simplistic formula. However, this is an excellent place to start when determining the optimum TV size for you.

Will it fit in your TV room?

Before selecting whether you want an HDTV, LCD TV, LED TV, or Ultra HD TV, you must first decide where you want your television to be placed. Once you've decided on a place, take measurements of its height, breadth, and depth. It may be limitations due to the size of an entertainment center or the amount of space on a wall. 

Later, while buying, you may compare this to the dimensions of the television itself, not its screen size, to ensure that it will fit. Some TVs have substantially more giant footprints than others with the same screen size, so always check the dimensions to see if they do into the area provided.

How vast is the stand?

The linked stand to the television is the second size-related factor. If you're not planning to mount your new TV to a wall, this will have a significant impact on how much room it takes up on your console table, and many modern TVs have feet on the extreme ends. You must verify that the area where you intend to place the television is large enough to fit the stand.

You'll want to be severe here as well. People frequently believe it is safe to let the corners overhang, forgetting that it was meant to rest on a surface level. If you don't, the slightest gust of wind may knock the whole thing over.

A universal TV stand is a good option when you can't wall-mount your TV and don't want to leave with a treasured piece of home theater furniture. VESA-certified arms are inserted into the back of your TV, similar to a standard TV wall mount, while a mounting bracket is attached to the stand's base. Many universal frames may also tilt and rotate up and down and from left to right.

How far away will you be?

You should consider where you'll be sitting concerning the television. There are viewing distance calculators (here's another one) that will recommend the size of your TV screen based on your seating distance. Suppose you don't want to use an internet calculator. In that case, you may use a more straightforward calculation to figure it out yourself: Multiply the distance between your seat and the television in inches by 0.84. It should provide you with the optimum screen size as well as the appropriate size for your area.

For example, if you sit 8 feet away from the TV, the formula asks for an 80-inch screen, which is just not feasible for most of us. Most living rooms will benefit from at least a 50-inch screen size, and, of course, taste, style, and viewing angle will play a significant role. You may potentially go as huge as you like and get a larger screen size - just make sure you're sitting more than 4 feet away from the TV, and you'll be fine.

Size and Quality

If you want to maximize screen real estate on a limited budget, you'll have to compromise image quality. As a result, as per our thorough TV buying advice, we recommend balancing the two aspects for long-term enjoyment. 

So, instead of shopping for the gigantic 65-inch 4K TV from an up-and-coming company that costs $500, consider the smaller 55-inch, big-name model next to it that costs $550. It most likely has a considerably higher screen and quality, which will result in a much more immersive watching experience, especially when utilizing HDR.

You should also consider the sort of information you will be seeing. If you're a Blu-ray or 4K streaming fan, your HDTV always presents the highest high-fidelity image your set can provide. If your TV is closer to 80 inches, or if you choose a 55-inch but sit closer to the screen, you won't notice any distortion in the image. 

On the other hand, if you enjoy watching older DVDs, VHS, and home video formats, but your living room has a TV with the same proportions as above, you will notice more significant distortion and flaws. Know what you enjoy watching and how much you enjoy watching it.


To summarize, there are more things to consider than just screen size. Consider the screen resolution as well as the overall arrangement of your space. Larger TVs work best in vast areas, while smaller TVs work better up close. You can determine the size of TV that would fit best in your space by measuring the viewing distance. To improve your watching experience, compare all of your alternatives before deciding on a TV.
