"Viewing distance
According to the American visual reproduction standard, THX, the best field of view is worked out by dividing the size of your TV screen in inches by .84. For example, if you’re looking at buying a 65in TV, divide it by .84 which equals a viewing distance of 77-inch, or 6.5 feet (1.9812 meters).
Below is a list of the most popular screen sizes. I’ve worked out the best viewing distance for each so you don’t have to get your calculator out.
28in = 33.3in, 2.7ft, 0.82296 meters
32in = 38.09in, 3.2ft, 0.97536 meters
40in = 47.61in, 4ft, 1.2192 meters
43in = 51.19in, 4.2ft, 1.28016 meters
48in = 57.14in, 4.8ft, 1.46304 meters
50in = 59.52in, 5ft, 1.52400 meters
55in = 65.47in, 5.4ft, 1.64592 meters
58in = 69.04in, 5.6ft, 1.70688 meters
60in = 71.42in, 6ft, 1.8288 meters
65in = 77.38in, 6.4ft, 1.95072 meters
75in = 89.28in, 7.4ft, 2.25552 meters
85in = 101.19in, 8.4ft, 2.56032 meters
You’ll see there’s a pattern. Basically, the number of inches the TV is diagonally can be divided by ten to achieve the distance it should be watched from in feet. So the thing to do now is to measure the distance from your sofa to where your new TV will go, and the closest match above gives you an idea of the TV screen size you should be looking to buy."
"HD or 4K
Those measurements above will let you see every detail of a Full HD resolution and you could move back by up to 50% and still make every detail out (presuming your eyesight is good enough). However, for the 4K screen you shouldn’t move further away from the display than the distances listed. That’s not to say sitting further back will eradicate the benefit of 4K but it will be lessened gradually until you get to around the double the distance stated, then you might as well have a standard TV instead."

Dare I say it? Holy crap! :o
I thought a 65" TV would be perfectly fine for me for 4K resolutions when sitting about 3 meters from the TV, but apparently I should sit around 2 meters away from the TV, or 6.5 feet, to get the full benefit of the 4K upgrade.
At 3 meters, or 9.8 feets, I need a 98 inch TV according to this list. :S
Maybe I should save my money for a 4K projector instead?
