# This is the Best TV Set Up Position, According to Maths

By Aatif Sulleyman on at

Trying to find the perfect spot for the best TV set up position? Here’s some devastating news for any of you who, like me, tend to watch football while lying on your side like a swimwear model, with your feet propped up against the nearest wall and your hand buried in a bowl of fancy crisps. That’s not the right way to do it.

Currys PC World and University of Essex lecturer Hongsheng Dai reckon they know best, coming up with a mathematical formula for what they believe is the ideal viewing experience. Are you ready to have your world turned upside down? Here’s what you need to know:

θ = tan^-1 (46/73.6)

Alright, realising that a lot of people will give up at Theta, they’ve also created an alternative formula for 4K TVs, which should be a little easier to follow. It still requires a little mental arithmetic, a protractor, a ruler and a key though:

AC=1.6 x TV (screen size)

Key:

• A = the middle point of the TV
• a = 30 degree angle which offers premium viewing experience
• B = 30 degree limit
• C = is the best spot for viewing 4K TV
• Line BC = offers quality viewing provided viewers provided they don’t sit outside of 30 degrees from the centre of the TV screen

What the above essentially says is that you should sit 1.6-times-your-TV-screen-size away from your telly, though Dai says you can switch the 1.6 for a 2.5 if you have a lower resolution TV or bigger screen. The angles thing indicates how far to the left- or right-of-centre you can get away with sitting.

Worked out what you need to do? Good. Good luck getting permission to rearrange the living room.
