TV Sizes and How to Calculate TV Dimensions: An Informative Guide

Television sets are a staple of modern living rooms around the world. From watching movies with family to gaming sessions with friends, TVs have become essential for entertainment.

With so many options available, it can be challenging to determine what television is right for your space. This guide will cover the basics of TV sizes and how to calculate TV dimensions.

TV Sizes and Prices

When it comes to buying a TV, price is usually the deciding factor. Affordability is essential, especially if you’re on a budget.

Conversely, some people may appreciate a premium price for outstanding features and superior quality. Whatever your preference may be, multiple TV sizes and prices can accommodate your budget.

Here’s what to expect:

Affordable TV Sizes:

– 32 Inches

– 43 Inches

– 50 Inches

Expensive TV Sizes:

– 55 Inches

– 65 Inches

– 75 Inches

While there is no set standard, TVs that are 40-50 inches in size tend to provide the best value. However, larger screens can also have their advantages, such as better resolution and clarity.

Ultimately, your space and budget will determine which size is right for you.

Common TV Sizes

Now that you know what to expect regarding TV sizes and prices, it’s time to consider the most common TV sizes. People usually buy televisions for living rooms, bedrooms, and other more confined spaces.

Here are the most common TV sizes and where they work best:

– 32 Inches: Ideal for small apartments, guest rooms, and bedrooms. – 43 Inches: Good for most living areas, including small living rooms and bedrooms.

– 50 Inches: Best for medium to large living rooms. – 55 Inches: Perfect for primary viewing locations, such as a family room.

– 65 Inches: Suitable for larger areas, such as a home theatre or great room. – 75 Inches: For the largest of spaces, like a dedicated media room.

Keep in mind that these sizes are merely a guide, and it’s always best to measure your space to make the right decision.

Aspect Ratios

TV aspect ratios determine how the image is displayed on the screen. The two most common ratios are 4:3 and 16:9.

The number represents how wide the screen is compared to how tall it is. – 4:3 Aspect Ratio: This ratio was popular in the early days of TV and was the standard until widescreen TV came out.

The aspect ratio is close to a square, with a much narrower shape than the 16:9 ratio. – 16:9 Aspect Ratio: This ratio is considered widescreen and is the current standard for most TV screens.

The shape provides a broader view than the 4:3 aspect ratio and can create an immersive viewing experience.

Calculating TV Dimensions

When determining which TV size to purchase, you’ll need to consider the TV’s height, width, and diagonal distance. It’s important to know how to calculate these measurements to ensure the perfect fit for your space.

Height and Width

To calculate the TV’s height and width, you can use the formula:

– Height = Screen Height Ratio x Screen Diagonal Length

– Width = Screen Width Ratio x Screen Diagonal Length

For example, if you have a 55-inch 16:9 aspect ratio TV, the height would be 27.50 inches and the width would be 48.94 inches.

Screen Diagonal Distance

The screen diagonal distance will determine how far apart to place your TV from seating areas in your room. To calculate the distance in inches, you can use the Pythagorean theorem:

– Diagonal Distance = square root of (Screen Width + Screen Height)

Televisions with a larger diagonal distance may be more suitable for larger areas and less suited to smaller spaces.


There is no one-size-fits-all solution when it comes to choosing a TV. To determine the ideal size and aspect ratio, you must consider your budget, space, and preference.

Hopefully, this guide gives you an insight into the most common TV sizes and prices, how to calculate dimensions, and make the best-informed decision possible. TV Size Chart and Viewing Distance: A Comprehensive Guide

With so many options available, selecting the right television size can be overwhelming.

Fortunately, the industry has standardized sizing created a chart based on aspect ratios. Along with a TV size chart, this guide will also cover viewing distances to enhance the viewing experience for both entertainment and practicality.

3:4 Aspect Ratio TV Size Chart

The 3:4 aspect ratio chart is best suited for older CRT TVs and some modern computer monitors. Here’s a chart listing the dimensions and surface areas of common TV sizes:

– 20 inches: 10.4” x 13.9” = 144.6 sq./in.

– 24 inches: 12.6” x 16.9” = 213.3 sq./in. – 27 inches: 14” x 18.7” = 261.8 sq./in.

– 32 inches: 16.6” x 22.1” = 366.86 sq./in. 16:9 Aspect Ratio TV Size Chart

The 16:9 aspect ratio is the standard for modern HDTVs and Ultra-HDTVs. This ratio provides a widescreen, cinematic picture.

Below is a chart that shows dimensions and surface areas of common 16:9 aspect ratio TV sizes:

– 32 inches: 15.7” x 27.9” = 437.63 sq./in. – 40 inches: 19.8” x 35.3” = 700.73 sq./in.

– 50 inches: 24.5” x 43.7” = 1068.65 sq./in. – 55 inches: 27” x 47.9” = 1289.3 sq./in.

– 65 inches: 31.9” x 56.7” = 1798.73 sq./in. – 75 inches: 36.2” x 64.3” = 2329.66 sq./in.

When considering TV size, we recommend taking surface area into account as it affects the overall viewing experience.

Optimal Viewing Distance

Optimal viewing distance refers to the distance between where you sit and your TV, where the image appears clear and sharp. To determine the optimal viewing distance, you must consider the screen size, resolution level, and personal preference.

The general rule of thumb is that you should sit about 1.5 to 2.5 times the diagonal length of the TV away from the screen. For example, if you have a 55-inch TV, the optimal viewing distance would be between 6.1 and 10.2 feet.

Other Viewing Distance Factors

While it’s essential to consider optimal viewing distance, several other factors affect the viewing experience:

TV Resolution: The higher the TV’s resolution, the closer you can sit and still see sharp images. For example, if you have a 4K TV, you can sit closer to the screen than you would with a 1080p TV and still get clear, detailed images.

Personal Preference: Personal preference varies from person to person. Some people prefer sitting close to the screen, while others prefer sitting farther away.

If you prefer sitting closer to the screen, you may need to adjust your optimal viewing distance. Room Size: The size of the room will also affect how far to sit away from the screen.

For larger rooms, you may need to sit far away from the TV, while smaller rooms require you to sit closer. Intended Use: Finally, your intended use will affect the optimal viewing distance.

If you’re using your TV for gaming, you may need a closer distance to see fine details. Conversely, if you’re using your TV for movies, you may need a farther distance to get the full cinematic experience.


Choosing the right TV size and viewing distance is essential for the best viewing experience. While the TV size chart and optimal viewing distance are a good starting point, you need to consider other factors such as room size, intended use, and personal preference.

By keeping these factors in mind, you can create an ideal setup for your TV, whether you’re gaming, watching movies or TV shows, or just enjoying some downtime. Different TV Technologies: A Detailed Guide

Technological advancements have led to various TV technologies available in the market.

Understanding these technologies will help you make an informed decision about which TV is best for your needs. Here is a comprehensive guide to the different TV technologies in existence.


Liquid Crystal Display (LCD) TVs use LED (Light Emitting Diodes) and CCFLs (Cold Cathode Fluorescent Lamps) to light up individual pixels on the screen. These TVs offer bright and vivid visuals with excellent contrast ratios and energy efficiency.

However, a limited viewing angle affects the picture quality’s quality, and blacks seem less dark due to the lamps’ inefficiency in producing deep blacks.


Organic Light-Emitting Diode (OLED) TVs use organic compounds to create light and offer optimum black levels and infinite contrast. As each pixel generates its light, no backlighting is required, making OLEDS thinner and lighter.

OLED TVs have a wide viewing angle, meaning the picture looks fantastic from virtually any angle, and they offer vibrant colors. However, OLEDs are prone to burn-in, where images can leave a permanent ghostly image on the screen.


Quantum Dot Light-Emitting Diode (QLED) TVs are similar to their OLED counterparts in that they do not use backlighting. Instead, they employ quantum dots to produce vibrant colors, improved contrast, and a broad color gamut.

QLEDs offer an excellent picture quality, better viewing angle than LCD, and are highly energy efficient. However, they do not match the pure black levels of OLEDs and may be prone to clouding, an issue where bright areas become blurry.

Plasma TV

Plasma TVs use a thin panel of gas to light up individual pixels and provide excellent picture quality, including deep blacks and a broad color gamut. Plasma panels are no longer in production, and you can only find them on the secondary market.

Since every pixel generates its light, you get an almost infinite viewing angle. However, plasma TVs are thicker and less energy-efficient than their LCD and OLED counterparts and are prone to image retention.


Ultimately, your choice of TV technology will depend on your preferences, budget, and the type of content you’ll be watching. While each technology has its unique selling points, it’s worth considering the viewing environment and usage before making a decision.

LCD TVs are cost-effective and offer excellent color, while

OLED TVs offer premium black levels and a broad viewing angle.

QLED TVs offer vibrant colors and a wide color gamut with better energy efficiency than LCD models.

Finally, if you can find one, plasma TVs offer deep blacks and excellent color quality, but they are bulky and less eco-friendly. With this guide at hand, you’re sure to make an informed decision that provides a fantastic viewing experience.

In conclusion, this guide offers a comprehensive understanding of TV technology, sizes, aspect ratios, optimal viewing distances, and the different types of TV technology. Selecting the perfect TV is no longer a blind choice.
