The most common mistake in picking TV size is not calculating viewing angle and distance and not considering room space before buying a TV.

For a better experience, choose the biggest screen size appropriate for your room with a higher screen resolution.

We always recommend getting a long-extending articulating TV mount because you can adjust it from different viewing angles.

Why are TVs getting bigger these days?

Over the years, the average TV size being sold is becoming bigger and bigger. Staying at home has become more prevalent than ever before. Home deliveries and streaming platforms have increased in popularity. As a result, people can stay home while still enjoying great entertainment without going to a restaurant or theater.

One study found that 55% [1] of Americans prefer drinking at home instead of going out to restaurants. On top of this TV, manufacturers are simply producing bigger TVs and making large high-tech televisions and home theaters more affordable for us. Data gathered by TrendForce found that the price of 65-inch TVs has dropped by 25% [2] while the price of 55-inch TVs has remained the same.

As a result of what we have found 65-inch TV has now become the most popular choice for households.

What is the optimal TV size for every scenario?

Are you wondering what TV size is right for you or how big should your TV be for the living room? Choosing the right TV size depends on the size of your room and budget.

This means you’ll want to know how far you’ll be sitting from the TV screen and how immersed you’d like your viewing experience to be. So what is the right TV size for viewing distance in your room? Here are a few pointers you can follow: 


  • If you’re seated about 6 feet from the TV, go with up to a 40-inch screen. 
  • If you’re 7.5 feet from your TV, a 50-inch works well. 
  • If you’re 9 feet away or more, we recommend at least a 60-inch screen for a theater-like experience. 

If you are mounting your TV, you may have more room to work with.


Is it necessary to get a bigger TV?

A bigger sized TV isn’t necessary, but there are some great benefits of having a bigger one.

Typically, if you get a higher picture quality like a 4K model, you’ll need a larger TV to appreciate the full potential of detail. Not to mention big TVs allow you to sit further away and more people can huddle around to see the screen. Overall, bigger TVs simply offer a better viewing experience.


Many people debate whether LCD or LED TVs are better. LED TVs have a thinner panel, use less power, have less heat dissipation, and offer a bright display with better contrast than conventional LCD TVs. That’s because LED TVs utilize light-emitting diodes as backlighting as opposed to higher quality CCFLs.

However, LED TVs can offer more colors, especially the technology that uses RGB-LED backlighting. This shows truer whites and blacks, meaning you can get a higher dynamic contrast. However, LED TVs are priced higher than most other LCD TVs out there. 

Should you use a home projector?

A home projector can be an alternative to using a TV, especially if you’re on a tight budget. Home projectors have a lower cost per screen inch, meaning they are much cheaper than TVs.

A projector’s screen size can be configured to be larger or smaller, but this can affect the motion image quality.

As a benefit projectors are portable, as long as you have an extension lead and mains power nearby so you can take one almost anywhere, and even set one up outdoors for a popular movie night. 

However, there are some problems that may dissuade you from buying a home projector.

For example, getting cable on a projector can be difficult. Most people simply use projectors for streaming services like Netflix and Hulu.

Lastly, projectors work best in dark rooms and don’t look as clear during the day. Also, you’ll likely need to purchase a separate portable sound system if you plan on using one outdoors.

Projector vs LED TVs

It may be tempting to go with projectors simply because they’re the more affordable option. However, LED TVs have a clear advantage when movies require high picture quality. LED TVs have a clearer image, and if you’re sitting at the right distance away from the screen, you have a better viewing experience. And this is possible if you use an extending TV wall mount. 

LED TVs are much more capable of providing higher brightness and better contrast. Projectors simply need to work harder to match the same brightness, and projector bulbs wear down over time. Not to mention, LED TVs are simply more advanced at this time. It’s quite standard to find 4K HDR TVs, and some now even come with 8K resolution. An 8K projector doesn’t exist.

Why does TV size affect the positioning and mounting options?

A TV size greatly impacts the TV mounting height. Before you can even mount or position your TV, you’ll need to know your TV size and viewing distance. 

Also, consider the size of your TV as this will affect your mounting. You’ll need to make sure that your TV mount is the correct size for your TV. For example, larger-sized TVs will need a TV mount that can accommodate their size.

Luckily, there are many TV mount sizes out there. There are even TV mounts for 75-inch TVs. The mount typically will match the VESA pattern of your TV.

And when mounting, you’ll need to measure the distances so that you can locate all the wall studs before you drill.

What goes wrong when choosing what TV size to install?

If you’re wondering how big should my TV be, you should always do your homework first. When people try to determine what size TV is right for a room design, here are a few common mistakes:

  • Not measuring the viewing distance ahead of time to calculate their ideal screen size.
  • Not considering all viewing angles.
  • You believe bigger is better without considering its picture quality.
  • Not considering the space you have available in your room for a TV.

Room domination: Considering the room size and space

It’s always best to factor in the right TV size for distance in your room. If you want to know how to determine the right TV size for a room, you’ll want to consider the same one you have available to you.

The further away you are from the screen, the bigger TV size you’ll need. 

For those who already have a console table or stand, consider whether or not the stand width will fit your TV.

Of course, make sure that you have room to fit your TV. If you have a crowded room, you’ll likely be better off mounting your TV to save space.

Measuring a TV for your room

If you’re considering how to pick the right size TV for your room, you’ll want to measure the distance between your desired location and where you’ll be sitting. Then you’ll need to understand that TV screens are measured diagonally from corner to corner, not by width. This means a 65-inch TV is likely closer to 55 inches wide. 

Viewing angle: TV height and distance between your seat and the TV

To get the most immersive experience, you need to identify your TV height and distance. Depending on your eyesight, beyond a certain distance, you won’t be able to distinguish every little detail.

When determining your TV size, you’ll also need to factor in the viewing angle and eye level from the floor while sitting.

Many TV manufacturers recommend that the TV should be parallel to your eyes with less than a 40-degree angle to the right or left and no more than a 15-degree angle up or down. 

Many people wonder, how big should my TV be from my couch and how to calculate it? However, you won’t need to worry about that.

With an extendable TV mount, you’ll be able to adjust the angle as you see fit. An extendable TV mount lets you adjust the distance and angle to accommodate people of different heights or various distances to suit.

Is screen size better than image quality?

Although it might seem like a bigger TV screen size is better than image quality, that’s not always the case. For example, lower resolutions on bigger TV screens aren’t as clear as higher resolutions on smaller screens.

All things equal, if you have two TV screens of the same size but different resolutions, the one with the highest resolution will be clearer. This means you’ll be able to discern more details.

However, it’s best to get a bigger TV with a higher resolution so that you get a more immersive experience while still being able to view every element in fine detail.

Different screen resolution types

Your screen resolution preference

Picking the right size TV vs sitting distance can be a challenge of only planning. Based on 1080p and 4K resolution, here’s a quick recommended distance you should be sitting away from the TV screen.

Recommended distance by resolution and tv size

Remember these

The more distance between you and the screen, the bigger the TV size should be. And the larger your TV and the more important the screen resolution is. Now that you’ve read through our guide, you’ll no longer have to ask the question of, how big should my television be or what size TV is right for me. 

We recommend getting an extendable TV mount since you’ll easily be able to control your viewing experience by adjusting the distance and viewing angle.
