Ever wonder why TV sizes are measured corner to corner instead of by height or width? The explanation dates back to when TVs first changed shape. They went from circular screens to rectangles. Measuring them diagonally gave the biggest number, making TVs seem larger to buyers.
This way of measuring is still used for all types of TVs, including today’s curved screens. By using inches to measure diagonally, companies have a common way to classify TV sizes. This makes it easier for people all over the world to compare. It helps in making ads more appealing and assists you in picking the perfect TV for your home.
The History Behind TV Measurements
TV measurements have changed a lot since the first circular screens. At first, TVs had circular screens, making diagonal measurements the best way to describe size. This method is still used today because it helps people everywhere understand TV sizes easily.
From Circular to Rectangular Screens
TV screens started as circular but became rectangular. The shape change improved the watching experience to be more like a movie. Today’s high-definition TVs usually have a widescreen format.
This move to rectangular TVs kept the diagonal measurement system. It gives a single, easy number to compare TV sizes, like 50, 65, and 75 inches. This way, everyone can understand TV sizes without confusion.
The Evolution of Display Technology
TV display technology has improved greatly over time. Now, we have OLED, LCD, and QLED TVs. These advancements mean better pictures and energy-saving TVs.
Companies such as Samsung, LG, and Sony are always coming up with new features. They introduce anti-blue light tech and flicker-free viewing. While how we measure TVs hasn’t changed, these innovations make watching better.
How TV Sizes Are Measured
When you know how TV sizes are measured, it makes choosing easier. TV screens used to be cathode-ray tubes (CRTs). Even with new LCD and OLED screens, the diagonal measurement method is still used.
Understanding Diagonal Measurements
TV screen size is the diagonal distance from one corner to another. This way of measuring makes it easy to compare TVs. Despite different aspect ratios, the diagonal is how we measure.
Comparing Inches to Centimeters
In many places, TV screens are measured in inches. But, some countries prefer centimeters. A 55-inch TV is about 139.7 centimeters. The inch is still the main unit for TVs, for ease of use.
Here are some sizes from well-known brands:
- Samsung: From 43.9 x 25.4 x 1.9 inches to 65.9 x 40.8 x 16 inches
- LG: From 44.1 x 25.7 x 2.6 inches to 65.8 x 40.4 x 14.1 inches
- Vizio: From 43.9 x 25.6 x 3.1 inches to 66 x 40.2 x 13.8 inches
- TCL: From 44 x 25.5 x 3.1 inches to 65.9 x 40.8 x 16 inches
Knowing about diagonal size and the inch to centimeter conversion helps in choosing a TV.
Marketing Tactics in TV Size Advertisement
TV ads often focus on screen size to attract buyers. They show bigger screen sizes to seem more appealing. Diagonal measurements make the TV look bigger than it really is.
Why Bigger Numbers Matter
Ads may say a TV is 50 inches, 65 inches, or even 75 inches. These big numbers actually measure the screen diagonally. This can make the TV seem larger than it is.
For instance, calling a 48.5-inch TV a 49-inch screen makes a big difference to buyers. Bigger TVs are thought to give a better watch experience. This strategy is very important in marketing.
The Role of Bezel Sizes
Bezels, or the frames around the screen, also influence how big a TV seems. They can add up to 3 inches to a TV’s size. Sometimes, TVs seem bigger because of the bezel size included in measurements.
For example, brands like Sony and Samsung might say a TV is 40 inches, not counting the bezel. This makes the screen appear larger. This method affects what buyers think and makes sure they get a good view.
Why Are TVs Measured Diagonally
TVs are measured corner to corner. This started with old CRT TVs that were round but showed rectangle pictures. The diagonal measure helps compare TVs of all types, no matter the technology or shape. Today, it still helps to compare TVs, like those from TCL, giving buyers a consistent reference.
Measuring diagonally shows the screen’s biggest size. It makes TVs seem larger, which people like when they want big, immersive screens. Yet, it’s smart to also check the TV’s height and width. This ensures the TV fits well in your space.
The switch to 16:9 aspect ratio was a big change, making widescreen TVs popular. Now, we even have 21:9 screens, mimicking movie theatre screens. TVs are often sorted into “classes” to account for slight size differences. This is due to how glass is cut in production.
Choosing a TV also involves thinking about how far you’ll sit from it. For the best view, your TV should fill about 40 degrees of your view. Simply, multiply the TV’s size by 1.2 to find the ideal viewing distance. For a 75-inch TV, sitting 90 inches away is best.
As TVs get bigger, resolution matters more. For big screens, 4K or higher is best to keep the image clear. Screen size feels different if the picture isn’t sharp enough.
Finally, when picking a TV, check its size, including its stand and edges, versus your room space. This makes sure your new TV fits and looks great in your viewing area.
The Viewing Distance Factor
Choosing the right TV includes knowing the best distance to sit from it. Usually, you should be 1.5 to 3 times the TV’s diagonal length away. For a 55-inch TV, stay between 8 and 13 feet away. This helps you watch comfortably and avoid eye strain.
How far you sit also depends on the TV’s resolution. For an HD 1080p TV, stay 3.2 times the picture height away. With a UHD 4K TV, you can get closer, at 1.6 times the height. For 8K UHD TVs, you only need to be 0.8 times the height away. This lets you dive into the action without seeing pixels.
Think about how you view the TV too. THX suggests sitting where the angle is about 40 degrees for deeper immersion. This usually means being 1.2 times the screen size away. For regular HDTVs, being 2.5 times the diagonal size away gives you a 20-degree angle. At 1.6 times the size, the angle is 30 degrees.
TV placement impacts your comfort too. Place your TV at eye level and angle it right to enjoy your shows more. With bigger TVs like 75″ or even 98″, how you set up your TV is crucial. For these large screens, go for 4K to keep the picture sharp and clear.
Samsung’s studies show people love bigger TVs and feel happy with their choice. When buying a TV, remember these tips on how far to sit. It ensures a great viewing experience.
Choosing the Right TV Size for Your Space
Finding the perfect TV size is key to a great watching experience. You need to think about how far you’ll sit from the TV, the size of your room, and what you like to watch. You should also consider how much you’re willing to spend.
Assessing Viewing Distance
The distance from your TV impacts what size you should buy. A TV size chart can help match the screen size with how far away you’ll sit. For the best view, a TV should fill a 30-degree angle of your vision for 1080p TVs. For 4K TVs, a 40-degree angle is better. THX suggests a simple calculation: divide the screen size by 0.835 to find the ideal distance.
Room Dimensions and Layout
Measuring your room is crucial for choosing a TV. TVs come in sizes from 32 inches to 85 inches. For instance, a 55-inch TV is about 47 inches wide. It should sit on furniture that holds its width well. Large credenzas can fit almost any TV size. But, the TV should not be wider than the furniture by more than 3 inches. This prevents it from tipping over.
Content Preferences and Budget
What you like to watch and your budget matter in picking a TV. Fans of sports or action movies might prefer a larger screen. If you can spend more, look for TVs with HDR or OLED/QLED tech for better quality images. Bigger screens do cost more, but the viewing experience they offer is worth it. Brands like Sony and LG have great options. Examples include the Sony Bravia XR A95K OLED TV and the LG C2 OLED TV. These offer excellent quality in various sizes to fit your space and budget.
Conclusion
TVs are measured diagonally due to old habits and marketing plans. This method gives a uniform way to share screen size. It takes into account different shapes and aspect ratios. Think about viewing distance, room size, and what you like to watch when picking out a TV.
A 75-inch TV is about 66 inches wide and 37 inches tall. It’s good for being 9.4 to 15.6 feet away. With LED, OLED, and QLED tech, you get better brightness, contrast, and colors. 4K and 8K resolutions make images clearer, improving how you see things on big screens.
