TV Dimensions and Sizes Guide

If you’re planning on getting yourself a new TV and wondering about the different sizes, this is for you. Read on to find out more about the various TV dimensions that are available.

All You Need to Know About TV Dimensions

So, you’ve finally gathered up enough to get yourself that new TV. Congratulations. But, there’s only one problem. You’re not sure of the size. TVs nowadays come in sizes ranging anywhere from 19″ to 105″ inches. This means, for many people, choosing the right TV size can be a tough nut to crack. But, it doesn’t have to be that way. Here, we are going to guide you on your quest to get the perfect TV size so you can get the most bang for your buck.

How Are TV Screens Sizes Calculated?

One of the mistakes that many people make when it comes to purchasing a new TV is in thinking that TV sizes are measured from side to side or top to bottom. Few people know this, the size of a TV is measured diagonally. This means it either starts from the top of one side and measures across to the bottom of the other side of the TV, or vice versa.

While measuring the size of a TV, it is important to start from the bezel of the TV, excluding the bezel itself, along with the frame of the TV. In other words, you will be placing the measuring tape from the start of the visible screen, rather than from the edge of the TV frame itself. This will always get you an accurate measurement of the size of the TV. The same measurement technique is used for measuring laptop screens and tablet screens as well because it provides you with an accurate measurement of the screen’s size.
It should also be noted that some vendors also try to trick customers when it comes to the size of the TV set. They do this by smart marketing gimmicks and by including the frame of the TV as well when providing measurements of the TV, which is inaccurate. While TV design is getting sleeker by the day, it can get difficult to notice the thin bezel around the TV screen, but even the addition of one inch can make a big difference in the price tag.

When it comes to TV sizes, big-name brands such as Sony, Samsung, and LG offer multiple sizes, making it easier for customers to find the perfect TV size that suits their needs. Keeping that in mind, some of the most common TV sizes that are available in the market today can be put in the following three categories:

  • Smaller sizes: up to 39 inches
  • Medium Sizes: 40 to 55 inches
  • Larger sizes: over 55 inches

However, the most common sizes produced by brands are 32, 49, 55, 65 inches.

32 inch TV Dimensions

The 32-inch TV measures at the height of 15.7 inches (39.9 cm) and width of 27.9 inches (70.9 cm). Getting the 32-inch TV set is the perfect choice for those who are looking for a TV at a viewing distance of 4.0 to 6.7 feet. Since the 32-inch TV is ideal for viewing from 4.9 feet, this makes it the best choice for those who want a TV for a small to a medium-size living room, bedroom, or kitchen area.

49 inch TV Dimensions

The 49-inch TV measures at the height of 24 inches (60.9 cm) and width of 42.6 inches (108.2 cm).

55 inch TV Dimensions

The 55-inch TV measures at the height of 27 inches (68.6 cm) and width of 47.9 inches (121.7 cm).

65 inch TV Dimensions

The 55-inch TV measures at the height of 31.9 inches (81 cm) and width of 56.7 inches (144 cm).

Calculating TV Sizes

For those who are having a hard time figuring out the exact size of the TV, here’s the formula that you can use to calculate the width and length of the TV for accurate dimensions and aspect ratio. So, what’s the difference between a 22-inch TV and 24-inch TV? This is an example of one of the main questions that people find asking themselves when purchasing a TV.

Well, you are going to need to use the Pythagorean Theorem and a few steps to get the accurate measurements. Here’s how you can find the exact size of the TV you are about to buy. You will have to start by finding out the aspect ratio, this will usually be around 16:9, but it can also be 16:10 in some cases. This means that for every 16 units of width, you have 9 units of height (or 10 in the case of the 16:10 aspect ratio).

Using the Pythagorean Theorem, you can add the width and height, which is 16 and 9, respectively, to get the hypotenuse (or diagonal) squared. For instance, with a 16:9 aspect ratio, you will have 162 + 92 = 337. By calculating the square root of this value, you will reach 18.4, as in for every 16 units of width and 9 units of height, the diagonal size will be 18.4 units.

It should be noted that two TV screens that have an identical aspect ratio will also have identical diagonals. So, now that you know the length of the diagonal, let’s calculate the width and height of the TV screen.
For example, if you have an aspect ratio of 16:9, for a 22-inch TV screen, you will get a value of 1.198 by dividing 22 by 18.4. You then use the value of 1.198 to convert the width and height of the TV screen into inches, which means, the actual width of the TV is going to measure at 16 x 1.198 = 19.17, while the height will be 9.0 x 1.198 = 10.78

So, there you have it. This is how you can make sure you get the accurate measurement of the TV screen you wish to purchase. Since this same technique can be replicated regardless of the size of the TV you wish to buy, you can always rest assured you will have the right measurements when it comes to the true size of a TV screen.
