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.

The Most Common TV Sizes Available on the Market
The most common TV sizes on the market today are 32”, 43”, 55″ and 65”. 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.

What Size TV Should You Buy?
The first thing to consider is the size of your room. A good rule of thumb is to multiply the diagonal width of the screen by 1.5 to get the recommended minimum size for your television. So, if you have a room that is 10 feet wide, you would need a television that is at least 15 inches diagonally.
TV Dimensions by Size
Here’s a breakdown of the most common TV sizes and their diagonals.
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 medium-sized living room, bedroom, or kitchen area.
When it comes to LCD HD televisions in the 32″ range, there are a lot of options. However, with 4K UHD resolutions, things change quite a bit. Samsung’s Q60A and The Frame are two popular 4K UHD TVs available.
42 Inch TV Dimensions
The screen of a 42 ″ television has a diagonal of 106.68 cm. with a height of 52.3 cm. and a width of 93 cm.
As of now, the 42 inch TV size is not as popular as it once was. Manufacturers have been releasing high-end versions ranging from 43 inches for some time. Samsung’s QLED and the Nanocell range from LG also begin at 43 inches. So, if you’re searching for the dimensions of television in this size range, keep reading and check out the next section for details on the 43″ because it will be more typical these days.
43 Inch TV Dimensions
A 43-Inch TV measures at the height of 21.1 inches (53.6 Cm) and width of 37.5 Inches (95.3 Cm).
Popular TV models that come in 43″ are the TCL 4K LED Smart TV and Samsung’s Crystal UHD line and also OLED. That’s why we picked it to be on our list of most popular TV sizes. A 43 Inch TV requires a viewing distance of 9.8 feet or less for optimum experience.
The smallest TV in Samsung’s Crystal UHD range will be a 43-Inch television, which will also be the most affordable. For this reason, if you’re looking for mid-range technology features and don’t want to spend a fortune on your new TV, this is the size to choose.
48 Inch TV Dimensions
A 48-inch TV measures at the height of 23.4 inches (59.8 cm) and width of 41.8 inches (106.3 cm).
48-inch TVs are where you start to get a really fantastic viewing experience. You’ll usually get a stand built-in to the TV base and you won’t need to pay more than a few hundred more dollars if you skip over a 42-inch TV for one this size.
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
A 55-inch TV measures at the height of 27 inches (68.6 cm) and width of 47.9 inches (121.7 cm).
55-inch TVs are noticeably more expensive than 48-inch TVs but you’ll get more options like UHD LED, LCD, OLED, and QLED TVs from brands like Samsung, LG, Sony, TLC, etc, at this size. Of course, the screens are much larger but because they are ultra-thin, they still don’t weigh much and can sit comfortably on a TV unit in your lounge. Movies look much better on a 55-inch TV thanks to the variety of technologies available. As well as this, colour depth and viewing angles are also significantly increased.
65 inch TV Dimensions
A 65-inch TV measures at the height of 31.9 inches (81 cm) and width of 56.7 inches (144 cm).
If you buy a 65-inch TV, you can be sure your friends will notice it when they come over for dinner. 65-inch TVs have become more and more popular in recent years thanks to the tariff war between manufacturers.
70, 75, 77-Inches
70-inch TVs and up are going to cost you a few more bucks than if you went for a typical 32-inch TV. 70-inch TVs are not the norm when it comes to picking a popular TV size because they are so big. However, as manufacturers look towards what the next best thing may be, more are jumping on board to build these monster sizes.
If you’re going to buy a TV bigger than 65-inches, you may as well go ahead and purchase a 77-inch TV because the leap from 65-inches to 70 or 75-inches is not all that much at all. If you’re going to go big, you may as well make it worthwhile. If you’re the type of person that wants an excessively large TV, it makes sense to get the biggest one in the range.
Of course, you’ll need a very large wall to mount it on as this size range usually won’t fit on a dresser, for example. Even though you’ll be paying out a lot for a 70+ inch TV, you can be sure you’ll be buying quality and you will most certainly have access to 4K and even 8K resolution. Watching movies in 8K on a TV in this size range is breathtaking and will be memorable for your friends and family.
83, 85, 86, 88-Inches
TVs in the 80-inch range are most definitely not popular TV sizes and are usually reserved for those who have a lot of spare cash to spend or those who are building small theatres in their homes. Like the 70-inch range, 80+ inch TVs are excessive in size and will require small wall mounts. However, there’s no denying that you will get a fantastic cinema-like experience, even just browsing Netflix or Youtube.
If you decide you want to buy a TV in the 80-inch range, you’ll need to make sure your wall is big enough and your TV is not going to be somewhere that has a lot of foot traffic where it can be easily damaged. If your 80+ inch TV gets damaged, it’s going to cost a lot more to get it fixed than if you went for a TV half the size. Over its lifetime, an 80+ inch TV will likely cost you more than if you went for a popular TV size.
90 Inch TV Dimensions
90 inch TVs are certainly not a popular TV size and are much rarer than any of the other TV sizes on our list. They are usually reserved for commercial environments or for conferences etc. To have one in your home you’d need a huge wall that can support the frame of such a mammoth TV. It’ll be harder to find a 90-inch TV that suits your particular needs too as most manufacturers only have vast ranges that cover the 50-inch size range and below. You’ll also need to take into account the price of a 90-inch TV which is usually twice that of an 80-inch TV so for 10 extra inches you’ll be paying double.
A 90-inch TV measures at the height of 44.8 inches (114 cm) and width of 79.5 inches (202 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 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.
