Updated April 12, 2022

The 75-79-inch market is expected to increase by around 35% in 2020 in North America compared to 2019. To understand the size of one of these televisions, you will have to know how wide is a 75 inch TV. TV sizes measure diagonally across the screen and do not include the bezel. The bezel is the portion of the TV surrounding the screen and this is why you should also consider this when getting the best TV in the market. The bezel size depends on several factors, including TV screen size, brand, and manufacturer. There is no standard bezel size.

KEY TAKEAWAYS:

• A 75 inch TV measures approximately 36.8 inches tall by 65.4 inches wide.
• For a 75 inch TV, the guidelines for viewing distance state you should sit about 10.2 feet away from the TV.
• The viewing distance guidelines vary based on who you ask, but most recommend a viewing angle of about 30 degrees.

## Calculating TV Dimensions

To calculate the height and width of a TV screen, you need to know the length of the diagonal, often expressed as “TV size” in a product name and the standard aspect ratio for widescreen TVs. Now that widescreen TVs are the most common type of TV, the aspect ratio for most TVs is 16:9 units, also expressed as 16/9 units. If the units are inches, that means the ratio is 16 inches for every 9 inches.

### Pythagorean Theorem For TV Screen Size

Using the Pythagorean Theorem, you need to know that the diagonal squared equals the height squared plus the width squared. This formula would be written as 75 squared inches equals 16x squared (width) plus 9x squared (height.) The 16 and 9 come from the aspect ratio. You would then solve for x.

To make this easier, we have found that you would need to multiply the diagonal by 0.87157553712 to find the width in inches. For the height in inches, you would need to multiply the diagonal by 0.49026123963. Once you have done the math, you should find that the dimensions for a 75” TV screen measure about 36.8 by 65.4 inches. Add a few inches on each side for the bezel, and you have the approximate size of the TV.

### 75 Inch TV Size Class

The TV size you find may not be accurate for TVs with “class” in the name. Brands that list their TVs with the word class following the size are capitalizing on a set standard. If the diagonal measures within half an inch of the 75” size, then the brands and manufacturers signify this using the word class. However, the difference is not always smaller, and it can also represent half an inch bigger TVs. If the description includes this, then the TV will not come out precisely the size you calculated. However, because the difference is only half an inch, the calculations shouldn’t be too far off. If you’re starting to become interested in a model that’s a few inches smaller, we have a whole list of best 70″ TVs. We also have several reviews on TV brands, like the best Vizio HDTV.

## Ideal Viewing Distance for TV

Many TV experts recommend certain viewing distances for different TVs. However, most of these people base their guidelines on the angular resolution of the TV and the visual angle. These aspects affect the viewing experience for people, whether they are watching a movie or show or playing a video game. Some people recommend sitting closer for video games and movies than for watching TV shows. If your watching environment has a lot of light come in, consider the type of TV itself, for the best TV for glare might be a suitable option if you can’t control the room light source completely.  If you also have a smaller living room then you may want to check how wide is a 70 inch tv.

### Angular Resolution

The angular resolution stems from the angle at which the eye can resolve the image on the screen. This feature measures the distance at which the adult eye sees the image as a whole rather than each of the pixels. If you sit too close for your eyes to resolve the image, you may feel like you’re looking through a screen door.

### Viewing Angle

The viewing angle refers to how much of your field of view the TV fills up. Different manufacturers may recommend different viewing angles. For some, the recommendation may be as high as 31 degrees, while others suggest a 10-degree viewing angle. The average retailer recommendation states that the view angle should be about 32 degrees. However, the Society of Motion Picture and Television Engineers recommends a viewing angle of about 30 degrees. A 75 inch TV allows you to even watch TV outside.

### Ideal Distance for a 75” TV

So, we’re going to work off a field of view of about 30 degrees. To find the proper distance for this, you would multiply the diagonal measurement by about 1.6264 for a 16:9 TV. Although the initial calculation comes in at about 121.98, you will need to divide by twelve because there are twelve inches in a foot. So, for a 75” TV, the recommendation would come in at about 10.2 feet.

With 75 inch TVs becoming more popular, many consumers will want to know the dimensions of these TVs. Additionally, they may want to know the recommended viewing distance. The size of the screen is about 36.8 inches tall by 65.4 inches wide. For this size TV, you ideally should sit about 10.2 feet away, based on the guidelines laid out by the Society of Motion Picture and Television Engineers.
