What are the sizes of 70 & 75-inch TVs

It’s been a long time since people watched live transmissions from a big box featuring a fuzzy image in black and white color. Nowadays, TVs are so modern that some feature special displays that can accurately replicate colors and small details. 

You can get on-demand entertainment on a big screen at a reasonable price. Still, the display technology is what changes the price tag of these TVs. OLED models are superior but more expensive, while UHD ones are more affordable. 


The dimensions of a 70″ TV are a width of 61″ and a height of 34.3″. The dimensions of a 72″ TV are a width of 65.4″ and a height of 36.8″.

Some of the most popular brands that offer 70″ and 75″ TVs are the following:

  • Vizio
  • Amazon Fire
  • TCL

If you are ready to change your TV out, you might be overwhelmed with many available options. That is why we did this research for you and picked the best ones for you to choose from. If you also wonder about the dimensions of 70 & 75-inch TVs, we will show you that. 

How are TVs measured?

It is not difficult to measure the TV size. This measurement refers to its diagonal length. All you have to do is find the distance from the upper left-hand corner to the lower right-hand corner. If you take this measurement, only consider the display, not the entire TV.

While the TV dimensions differ, getting the largest size your budget allows is often recommended. Many people choose the biggest size available and are often satisfied with their decision. TVs are measured without the bezel or frame that is present around the edge of the screen.

That is because only the display size matters, which is the same across various models. However, the frame might be thinner or thicker. Small LED TVs will start at just 28 inches, while the largest OLED screens can reach up to 80 inches. 


The 70-inch size is a common one for TVs. Many people choose this size when they consider upgrading their old TV. It is ideal for interior spaces and suitable for large living rooms. If you consider getting a TV of this size, you should expect high-quality and highly-defined pictures.

Depending on the manufacturer, you will find some 70-inch TVs overpriced. Some companies might inflate the price tag to encourage you to go bigger, but you should always choose the best one for you.

Overall, a 70-inch TV has a height of 34.3 inches and a width of 61 inches. The diagonal measurement of the television will be 70 inches, so you should consider this size and find an ideal space for the TV in your room. 

The width of a 70-inch TV is 61 inches, which is smaller than its diagonal measurement. Keep in mind that these devices are designed for an aspect ratio of 16:9 units. You should also consider the width as an important factor to look for. 

Your TV will come with a chart that will specify its size both in the imperial and metric systems. When companies design their TVs, they use special formulas that include algebra and trigonometry to figure out the best dimensions for their product.

While most of the specifications are provided for the display itself, you should also keep the bezel of the TV in mind. Some manufacturers will aim for a thin display with sharp edges where the screen occupies most of the front side. Some older models will have thicker frames, which will take up more screen space. 

TV dimensions chart by size

Knowing your TV’s actual size before purchasing it is crucial. When advertised, most will feature the diagonal measurement of their display. But if it features a thicker frame, the actual size might be significantly bigger.

These measurements use old standards, and they apply to TVs that have an aspect ratio of 3:4. But nowadays, the newer models feature an aspect ratio of 16:9. At the same time, some displays can even reach 21:9. This resolution has a lower height, but they are much wider.

For new models, you can consider 0.5 to 1.5 inches to be the thickness of their bezel or frame. This frame holds the screen, but companies focus on further reducing its thickness. Converting the size manually might be difficult. That is why we provide you with a table below that already features the conversions of the most popular TV sizes.

Viewing distance

There is a specifically recommended TV viewing distance for all sizes. You might want to consider this distance before installing the new device at home. Experts recommend 40 degrees of field of view to be taken by the screen for the most immersive experience.

The field of view can be calculated simply by knowing the size of your TV. Multiply it by 1.2 to 2, and then you get the ideal distance. For example, a 75-inch TV has a suitable sitting distance of 90 to 150 inches, which is an acceptable range. 

At this point, you will be able to fully immerse in the image and see all the small details while also keeping your eyes safe from inadequate screen exposure. Sometimes you might be too excited about buying a new TV and completely forget about the place where you want to install it.

TV SizeRecommended Viewing Distance
26 inches4.3 feet
32 inches5.3 feet
40 inches6.7 feet
50 inches8.3 feet
65 inches11 feet
75 inches12.5 feet
75 inch tv

That is why you should decide on this factor before leaving your home and heading towards the electronics store. Prepare your room beforehand and calculate the viewing distance using the simple method presented above. If you want to install the TV in a tight space, take exact measurements of the available area and look for a TV that can easily fit. 

Remember that their size is often represented as the display size, which is measured diagonally. TVs with thicker frames will be bigger than their diagonal measurement. Compare the exact width and height of your furniture and ensure it can fit perfectly. 

The total pixel count should proportionally increase with the screen size. The better the resolution, the higher the clarity. While there are many options on the market, you should also consider the display technology and quality instead of focusing only on the size.

If you prefer a larger TV, look for a higher pixel count and a sharper resolution. You don’t want to end up with a large screen that cannot display sharp images and accurate colors.
