75-Inch TV Dimensions – ElectronicsHub

When we speak about the dimensions of a TV (like, in this case, a 75-inch TV), we discuss its height, width, and thickness. Without knowing these dimensions, one cannot judge if the TV would fit correctly by mounting it on the wall or placing it on a stand.

So this article comprises detailed information on many aspects that impact these dimensions, their calculation, and much more.

How Wide is a 75-inch TV?

When deciding on which TV you should buy, the consideration of the bezel that’s around the TV screen becomes crucial. This is because we measure the dimensions of a TV diagonally without counting in the bezel.

Moreover, bezel size is not constant, and factors like TV brand, its size, manufacturer, and so on impact the size of the bezel.

Talking of a 75-inch TV, the width of the same comes out to be 65.37 inches approximately (i.e. 166 cm). This measurement comes out based on the 16:9 aspect ratio that is put to use to measure dimensions for all TVs. But you should know a TV’s dimensions could be slightly different depending on what TV model, manufacturer, etc., you are choosing.

How to Calculate TV Dimensions?

The various aspects that impact the calculation of TV dimensions involve the following:

1. Aspect Ratio: The aspect ratio is basically the TV screen’s correlative relationship between height and width.  16:9 spect ratio tends to be highly common for most TVs. Other aspect ratios could be 4:3, 21:9, and more.

2. Diagonal Size: The measurement of the TV screen diagonally can be done from the TV screen’s one corner to the TV’s opposite corner. This measurement, in general, comes out in inches.

3. Height/Width: On having the diagonal size and required aspect ratio, now, you must look forward to calculating the height and width with the help of these given formulas:

  • Height: Diagonal size * (height factor of the aspect ratio) = TV height
  • Width: Diagonal size * (width factor of the aspect ratio) = TV width

Now, when running a calculation for a 75-inch TV considering the 16:9 aspect ratio, the dimensions come out to be:

  • Width: 75 * (16 / √(16^2 + 9^2)) = 65.37 inches approx.
  • Height: 75 * (9 / √(16^2 + 9^2)) = 36.77 inches approx.

Note: The calculation done above is for a TV screen that’s rectangular in shape.

In most cases, the space a room has is good enough to incorporate a TV, but if you are still unsure, here’s a list of factors that may help:

1. Viewing Distance

This denotes the distance between you as the viewer and your TV. Regarding a 75-inch TV, remember that you sit at a viewing distance of about 1.5 to 2.5 times the dimension of the diagonal screen size.

Hence, in the case of a 75” TV, the viewing distance suggested to be followed is about 6.3 – 9.4 feet.

40″ 3.3 to 5 feet
43″ 3.6 to 5.4 feet
50″ 4.2 to 6.3 feet
55″ 4.6 to 6.9 feet
60″ 5 to 7.5 feet
65″ 5.4 to 8.1 feet
70″ 5.8 to  8.75 feet
75″ 6.3 to 9.4 feet
80″ 6.7 to 10 feet
85″ 7.1 to 10.6 feet

2. Room Layout and Furniture Placement

Look forward to your room’s overall layout and seeing how much space you have available to incorporate the TV. You can opt for the wall or stand measurement where you wish to mount or put the TV and check for how comfortable the seating arrangements are in terms of space.

See if the distance between the seating and your TV is enough for comfortable viewing angles. In addition, check for the TV height when seated and see if it’s located at your eye level.

3. Viewing Angle

To experience optimum viewing, ensure that you have an appreciable viewing angle. Position your big-screen TV so you can view the same directly, and no straining or too much tilting is required or involved.
