When it comes to televisions, bigger isn't always better. Yes, if you have a huge living room then a giant TV is great. However, if your living room is on the smaller side, then you can end up in a situation where you're sitting way too close to that massive screen, even when you're technically sitting on the other side of the room.
So, what size is right for you? You can figure out pretty quickly by deciding where you plan on sitting to watch it and measuring the distance between there and where you plan on placing the TV. After that, it's just a little maths.
According to Samsung, the right TV size is the viewing distance (in inches) divided by three.
For instance, if you plan on sitting 3 metres from your television, then you're around 120 inches away. When you divide 120 by 3, you get 40. That means that the right TV size for your room is 102cm, or 40 inches.
Viewing angles are also something to consider once you make that purchase.
Here's what Samsung has to say about that:
"Ideally, the TV should be placed parallel to your eyes, with no more than a 15-degree angle up or down and no more than a 40-degree angle to the left or right. If you are seated at a sharp angle to the TV, you may see negative images on the screen. Most major manufacturers will tell you the maximum viewing angles at which you can watch the TV without seeing negative images. For example, a 170/170 angle measurement means you can still see a good image 170 degrees up or down from the center of the screen."
Pick the right size and pay attention to where you hang it, your eyes will be happy you did come hour five of that Netflix marathon.
