Consumers looking to buy the best TV in the market may ask how wide is a 70-inch TV. To understand the height and width, you have to know that the 70” size covers the diagonal of the screen. This measurement may seem counter-intuitive because most things are represented by height or width. However, many electronics with screens are measured the same way. Additionally, consumers may wonder what features are available on a 70-inch TV.


  • The height of a 70-inch TV screen is about 34.3 inches, while the width is about 61 inches.
  • You should sit about 9.8 feet away from the screen of a 70-inch TV.
  • Many 70-inch TVs feature higher resolutions than TVs of the past, including FHD, 4K, and 8K resolutions.

70 Inch TV Dimensions

When calculating the dimensions of a 70-inch TV screen, you could use a system of formulas outlined on various websites only. These formulae include algebra, using the Pythagorean Theory, or trigonometry, which is based upon angles. You would also have to know that the most common aspect ratio for widescreen TVs is 16:9 units. However, you can most likely find this information in the form of a chart for many standard TV sizes. Either way, you should see the measurements for the screen are 34.3 inches by 61 inches.

In addition to the screen size, the TV’s dimensions depeXZnd on the size of the bezel on the TV, as well as the depth. You may review how wide is a 75-inch tv and also read our Samsung UN75TU8000FXZA review for a slightly larger model that would not be curtailed by a larger bezel. The bezel is the edge of the TV that surrounds the screen.

If you picture a standard TV, you would recognize the bezel as being the black part of the TV that is around the viewing area. If you are not hanging the TV on the wall, the stand may also add height. The amount of height added depends on the TV model.

The depth of the TV refers to the distance from the front of the TV to the furthest back part, though the stand may add some depth to the TV as well. Generally speaking, for a more immersive experience, aim for a TV that’s at least 40 inches wide from 10-12 feet away from where you’ll be sitting. This distance can vary depending on how big your room is and how big the TV is. For a more comfortable viewing experience, use the rule of thumb to determine the ideal viewing distance, especially if you’re measuring for a 70″ TV. 

70 Inch TV Viewing Distance

The size of the room where the TV would be placed also impacts the ideal size of the TV. The guidelines for viewing distance state that you should sit 9.8 feet away from the screen for a 70” TV. These guidelines consider angles and how much of the field of view the screen should take up. However, the people who recommend the distance acknowledge that this distance may not be suitable for everyone. If you have a smaller room then you can see how wide a 65-inch TV is. Personal preference also comes into play when choosing a viewing distance. Keep in mind the lighting quality of the room alongside distance. If you’re planning to set up your TV in a bright area, consider investing in the best TV for glare.

Resolution on the 70-Inch TV

Consumers can find 70-inch TVs with varying resolutions, spanning full-high definition (FHD,) 4K ultra-high definition (UHD,) and 8K UHD. FHD was pretty standard for TVs following the switch from analog to digital broadcasting. The full-high definition resolution increases the image quality since analog TV.

In fact, 4K and 8K UHD provide picture quality that is four to eight times the resolution of FHD. 4K UHD TVs are available in flat-screen designs, which are popular for their slim profile and sleek look. With 70 inches being one of the largest screens on the market, consumers can enjoy a truly immersive viewing experience with picture quality that rivals the cinema.

In recent years, the market for TVs has begun to shift away from FHD toward 4K TVs. The transition to 8K recently started happening and is still ongoing. Both 4K and 8K TVs have higher resolution than FHD. The “4K” and “8K” represent the number of pixels across the horizontal axis of the TV.

FHD 70-Inch TVs

Many consider full-high definition TVs to have a typically higher resolution than their HD counterparts. FHD TVs feature a resolution of 1920×1080 pixels. The resolution depends heavily on the pixels per inch (PPI.) Much like those calculating the height and width, those calculating the PPI have a bit of math to do.

However, you can find the estimate for the PPI online. For a 70-inch TV with full-high definition, the PPI is about 21.470. FHD TVs may not offer as much image quality as the others, but these TVs come with a lower price tag than most 4K and 8K TVs.

It may be smarter to look for a smaller screen size if you want to stick with just FHD as it won’t look as bad since the screen is smaller, however. A large average size television screen can provide an incredibly vivid picture and contrast that looks stunning when watching movies, but the resolution isn’t as strong. As you increase the size of your TV, the pixels become more stretched, leading to poor image quality on a Full HD display.

70 Inch 4K UHD TVs

Many 4K UHD TVs feature a high pixel count, as indicated by the number of pixels. For example, a 70-inch 4K TV holds about 62.940 PPI. The PPI is not the same for all 4K TVs because the size of the TV affects how spread out the pixels are. UHD represents TVs with a resolution of 3840×2160 pixels or higher. While your eyes may not be able to tell the difference at a certain point, your next TV will more than likely be a 4K TV anyway. 8K theoretically offers increased image quality than 4K TV, but 4K TVs are more readily available.

70 Inch 8K UHD TVs

Manufacturers who have created 8K TVs still categorize 8K TVs as UHD, though the standard fits the 4K TVs. These 8K TVs feature about 8,000 pixels across the horizontal axis. The increased number of pixels should allow for an increase in details on the screen. The most important feature of an 8K TV comes from how well it upscales images because most content is not formatted for 8K TVs. A 70” 8K TV contains about 125.880 PPI.


What role does seat distance play in the television experience?

Seat distance plays a role in the TV experience because the eyes can only resolve the images on the TV at a certain distance. Additionally, the closer you sit to the TV, the more the TV fills up your field of view. Therefore, the TV should only take up a portion of your field of view.

What is the height and width of a 70-inch TV?

The width of a 70-inch TV screen is about 61 inches with a height of 34.3 inches, though this does not include the bezel of the TV.

How do I change the picture resolution?

Many TVs feature the ability to change the picture resolution using the “Picture” or “Display” setting option.

STAT: While your eyes may not be able to tell the difference at a certain point, your next TV will more than likely be a 4k TV anyway. (source)
