Many consumers consider multiple possible TV sizes when determining the size of their next TV. There is a wide range of TV sizing, spanning 24” to 75” for standard TV sizes. As a result, many find themselves considering what sizes TVs come in when looking for the best TVs in the market. To understand the different screen sizes, you should know the actual dimensions of the TV screen and the recommended viewing distance for viewers to sit away from the TV.

KEY TAKEAWAYS:

  • Brands manufacture smaller-sized TVs in the 24 inches, 32 inches, and 40 inches sizes, though fewer and fewer make 24-inch TVs today.
  • For medium-sized TVs, consumers find displays around 55 inches, 60 inches, and 65 inches to be the right size for medium-sized TVs.
  • Larger-sized TVs measure about 65 inches, 70 inches, and 75 inches, though several models are larger than 75 inches.

Calculating TV Screen Sizes and Distances

To calculate the size of a TV screen, you would take the length of the diagonal, which is stated by the size in the name, and the most common aspect ratio for TVs, which is 16:9. You could then use the Pythagorean Theorem to find the approximate size of the screen. We have done that for you, and you can find the results below. Be sure to add a few inches on each side to accommodate the TV’s bezel. You may also want to find out what is streaming tv and how it works as it will also influence the TV size you purchase.

For viewing distance, mathematicians have found a much easier way to calculate the recommended distance. According to the Society of Motion Picture & Television Engineers (SMPTE), your TV should occupy at least a 30-degree arc in your field of vision. Finding this distance for each TV is as easy as multiplying the diagonal by 1.6 inches for a high-definition (HD) TV, which most TVs are.

Most Common TV Sizes

When buying a new TV, you should consider what size you want and what room the TV would be going in. The most common TV sizes include:

  • Smaller size TVs are perfect for a smaller room, such as the bedroom, guest room, or kitchen.
    • 24” – People consider 24-inch TVs to be “small” in size. The height is roughly 11.7 inches, and the width is 20.9 inches. The viewer should sit just over 3 feet away from the TV. Some manufacturers no longer make 24” displays.
    • 32” – These 32 Inch TVs are still considered small size. 32” TVs offer the same comfort as the 24 inches but with a slightly larger screen. These TVs typically measure around 15.7 inches tall by 27.9 inches wide. For a field of view of 30°, you may want to sit about 4.5 feet away. Many manufacturers make 32” TVs as their smallest size.
    • 40” – Many 40-inch TVs are considered to be small in size as well. These TVs typically stand about 19.6” tall by 34.9” wide, and the guidelines for a 40” TV suggest sitting approximately 2.5 feet away.
  • Medium size TVs are perfect for smaller living rooms and other medium-sized rooms. Many consider these TVs ideal for narrower rooms as well.
    • 55” – A 55-inch TV screen comes in at 47.9 in. wide and 27 in. tall with a viewing distance of 7.7’.
    • 60” – Standard 60-inch widescreen TVs are approximately 29.4 inches tall with a width of 52.3 inches. Therefore, a viewing distance of 8 feet follows the guidelines for a 60-inch TV.
  • Many living rooms and outdoor areas feature larger TVs, many of which include the best features.
    • 65” – The 65-inch TV is one of the larger TVs widely available. It measures about 31.9”x56.7” and has a recommended viewing distance of 9.1 feet. These larger sizes are great for both the living room and the workplace as well in case you need to present something and are looking for something like the best conference room TV.
    • 70” – Many 70” TVs are about 34.3×61 inches, while the recommended viewing distance is about 9.8 feet.
    • 75” – A 70-inch TV remains one of the bigger TVs available, though there are some that are substantially bigger. The 70” TV stands approximately 36.8 inches tall by 65.4 inches wide. The recommended viewing distance is about 10.2 feet away.

It should be noted that if you see a class with the size, for example, a 40″ class TV, it means that the TV is not actually a 40-inch TV. We have a great article on what class means on a TV that you can check out as well. Knowing this can also help you understand how to choose a TV screen size and weight among other considerations. Additionally, knowing the size and weight of the TV helps tremendously if you are going to be mounting it on the wall. Just be sure to take into consideration if it is a curved TV as this could affect where you mount it. If you are a gamer then size should be included in what to look for in a gaming tv as it will impact your gaming experience. Lastly, if you are considering buying a used TV you may come across some screen types that aren’t manufactured anymore, like plasma. If you would like, you can learn more about what a plasma TV is so that you can make an informed decision if you are considering purchasing one.
