You can grab a 30-inch to 40-inch screen for basic viewing while for a cinematic experience, you may have to get a big screen from 45 inches and above. The larger the TV size, width, and height, the better because it comes with more detail.

Dimension of a 42 inch TV

If you like hosting movie nights, you also need to check the TV’s viewing distance and angle. A TV with a great viewing angle with excellent picture quality will serve you perfectly in this case. You do not have to squeeze on one sofa for you and your friends to get a great view of that favorite series.

A TV stand that fits your TV right, leaving some few inches on its sides, makes the screen look vibrant. Measure the TV’s width plus the bezel, then buy a stand that is a few inches wider to enjoy your favorite movie.

What Is The Standard Measurement of TV Screens?

When most people plan to buy a TV, they perceive that the TV dimensions are from side to side or top to bottom. Typically, the TV size is measured diagonally. So when you hear the seller describe that a specific TV is 42 inches, it is the distance from top right to bottom left or top left to bottom right.

While measuring the size of your TV, you have to place the tape on top of your screen from the bezel of the TV (not including the bezel itself and the frame of your TV). In simple terms, you are to set the tape on the visible screen. You must stretch the tape straight across and avoid any slackness because it may give you inaccurate measurements.

We also apply this technique to measuring laptop screens and tablet screens because it gives correct measurements. Note that some vendors try to dupe some customers. They do this through the use of smart marketing gimmicks and including the frame of the TV when measuring its size, which is inaccurate.

Since the TV designs are getting sleeker, it may be difficult to notice the slim bezel around the screen. But even adding 1 inch to the TV dimensions can make a huge difference in the price.

The larger the screen size, the better it serves you. But this means that you might have to pay more money, clear more space to mount it, or even buy a huge cabinet. If you prefer a large TV, you may want to first read our review on the best TV dimensions for large TVs (80 inches) before you buy.

How to Measure Height-Width TV Dimensions

Use a Tape Measure

To measure the width of your TV, run the tape measure horizontally from the right side to the left or vice versa excluding the bezel. Ensure the tape does not have any form of slackness to get the accurate width measurement.

To get the height, place the tape from top to bottom of your TV on one side. Remember to exclude the bezel and ensure that the tape is not droopy. The measurement you get is the height.

Use the Screen Size and the Aspect Ratio

You can get the height and width of your TV without actually measuring. You only need the screen size and the aspect ratio. Here is a simple way to calculate these TV dimensions.

1. Find the Aspect Ratio Diagonal

If we have a 22 inch TV screen and its aspect ratio is 16:9, then using Pythagoras theorem a2 + b2 =c2 we can get our aspect ratio diagonal c2 = 162 + 92 = 337. So our (aspect ratio diagonal)c = √337 = 18.4 inches.

2. Find the Diagonal Ratio To Aspect Ratio Diagonal

Our diagonal ratio, in this case, is 22inches and the aspect ratio diagonal is 18.4 inches giving us 22/18.4 = 1.198

3. Use the Step 2 Result To Get the Width and Height

Using the number 1.198 we can convert the height and width directly in inches. Therefore the TV width will be 16 x 1.198 = 19.17 inches. The height will be 9 x 1.198 = 10.78 inches.

When we compare other screen sizes with the same aspect ratio, let’s say 52-inch screen or 75-inch, the height and width will increase. Consequently, the size of the pictures will be larger giving you an amazing watching or gaming experience. An advantage and motivation to get a TV with great height and width.

Ideal TV Viewing Distance

The right viewing distance is vital for you to improve your watching experience. If you sit too close to the TV, you may see the pixilation squares on the screen, depriving you of the high-definition details. It may also affect your eyes wellness, more so those of the kids, since they are more delicate.

If you are watching an HDTV, you can simply calculate the minimum viewing TV distance to avoid these by multiplying the screen diagonal with 1.5. For instance, a 60 inch TV would have a viewing distance of 90 inches or 7.5 feet

“So, what is the perfect TV viewing distance recommended by experts?” You ask. Well, no official bodies exist currently to guide on this, but the THX, a leading company in the world of surround music, recommends the TV viewing distance to be as follows.

viewing distance of a tv

To calculate the perfect distance between your seat and screen, (for a TV or projection screen), divide the screen size by 84. For instance, a 65inch TV would have a 77 inches viewing distance of 6.5 feet.

In case you want to set up your HDTV in a room that has limited space, the THX recommends 3.5-5 feet for 32 inches, 4–6 feet for 40 inches, 5-7.5 feet for 50inch, and 6-9 feet for 60 inch TV.

These measurements seem very large for the particular room size, but it is important to note that the THX bases them on two things. They found it on generating an immersive cinematic experience, and the complaint of many clients who wish they had bought a bigger screen.

The distance calculation recommended by the THX is fit for the current generation Ultra HDTV, but for the regular HDTV, we maintain 1.5 times the screen size.

TV Side Viewing Angles

The TV side viewing angle is how far to the right or left you can sit to watch your TV. If you sit straight to the TV, you are at zero degrees. When you start moving to the right or left side, the angle increases to 90 degrees when you get to the point that is parallel to the TV. The best point to get the most out of your watching experience is at zero degrees.

Most manufacturers specify the whole viewing angle that is from the furthest right to the furthest left. The maximum viewing angle, in this case, would be 180 degrees. i.e., (90 + 90).

Depending on the type of TV you buy, the screen gives different picture quality as the viewing angle increases. If you love having movie nights with your friends, then a TV with good picture quality at great viewing angles would serve you and your friends comfortably.

You should also consider the place where you set your TV to have a fantastic watching experience. The eye level determines the best level to place your TV. Set your TV below eye level because naturally, you are more comfortable watching TV looking slightly down than up.

TV Stand Dimension

When clients visit online shops, they often get overwhelmed by the numerous TV stands they see. If you relate to this scenario, then you may want to learn this straightforward approach to get that ideal stand that fits your TV dimensions.

  • Get the width measurement of your TV.
  • Add the bezel measurement.
  • The final result you get, i.e., (TV width + bezel), select a moderately longer stand than this.

For instance, for a 30 to 38 inch TV, you can get a stand that is 35 inches or lower since its width with the bezel is 28 to 35 inches. As the TV size increases, the stand width also increases.

Do you want to get the most out of your TV? You need to know the different TV dimensions that will serve you right. Besides, you deserve the best after spending some money to purchase it.

To get an amazing view and avoid some vendors conning you, you can measure the TV’s size diagonally while excluding the bezel and repeat this to get the width and height. Alternatively, you can use Pythagoras theory with the screen size and aspect ratio to get the width and height.

Knowing the correct viewing distance and viewing angles is also a step forward to great viewing. It helps you have a comfortable viewing without straining your eyes and eliminating the pixilation squares, which can be distracting.

The TV stand is also crucial, so you need to choose one that is a few inches longer than the TV’s width plus the bezel. With these guidelines in place, you can be sure to have an extraordinary watching experience. So, as a rule of thumb, always put your TV dimensions in mind when purchasing a TV.
