Here’s how to work out what size TV you should buy


If you are thinking of buying a new TV anytime soon, the first thing that goes through your mind is “bigger is better” – it’s only natural right?

When in actual fact that isn’t the case as you need to take the size of your room into account along with viewing angles.

Luckily, there is a scientific formula available that will help establish what size TV you should be looking to purchase.

The formula is known as THX, and states that in order to find out the size of TV which is best for your room, you need to work out what is the best field of view (FOV). This is done by dividing the size of your TV screen in inches by 0.84.

So if you want to buy a 65inch TV, dividing it by 0.84 gives you a viewing distance of 77 inches or 6.5 feet.

Tech Site, Expert Reviews, have compiled the list below that lets you know the best viewing distance for each size of TV:

28in = 33.3in (2.7ft)
32in = 38.09in (3.2ft)
40in = 47.61in (4ft)
43in = 51.19in (4.2ft)
48in = 57.14in (4.8in)
50in = 59.52in (5ft)
55in = 65.47in (5.4ft)
58in = 69.04in (5.6ft)
60in = 71.42in (6ft)
65in = 77.38in (6.4ft)
75in = 89.28in (7.4ft)
85in = 101.19in (8.4ft)

Once you have established the size of TV that you require for your room, there are some other things you need to consider.

Firstly you need to consider if you wish to go for a 4K TV.

4K TVs have a much larger pixel resolution (3,840 x 2160) than the Full HD standard (1,920 x 1,080).

Although a couple of years ago we would probably have said that you didn’t need a 4K TV they may now be worth considering, especially if you are an avid Netflix, Amazon Prime or YouTube viewer.

You then need to consider the screen itself with OLED being the clear winner although 4K OLED screens are not so easy to come by at the present time.

They are far more costly than a standard LCD screen so you perhaps maybe need to take this into consideration before choosing as this is something that you could perhaps sacrifice.

Whatever you choose, we are sure you will a great viewing experience with most models being pretty reasonable these days.
