For the best viewing experience, you’ll need the picture to fill up your entire field of vision. This is not the typical viewing area from your eyes, but rather of how much you can see or view while in sitting down position. Thus, for the most immersive experience, you would need the largest TV screen possible that would meet your room size, budget, mounting hardware/stand while also accommodate to the viewing distance.
Best Seating distance for TV screen sizes
Again, if your budget allow, buying the largest possible TV that work with your room size turn out to be the best solution. Still, this is a two conditions verse, that is if the TV is too big for your room, you’re at risk of straining your eyes while an undersized TV doesn’t give you all the details of displaying picture.
So before buying, measure the distance where the TV will be mounted or placed to where the sofa or seating structures will be. From there you will have a pretty good idea on which TV size would be to provide the best viewing area.
Typically for an 1080 HDTV, the viewing distance should be 1.5 to 2.5 times of the screen size while for the 4K ultra HD it’s only 1 to 1.5 ratio. Different resolution has different viewing distance as well. For your information, see the below table for a general TV screen size optimal viewing distances.
| TV screen size | Best Viewing distance range for 1080 HDTV | Best Viewing distance range for 4K UltraHD TV |
| 40” | 5 ft – 8.3 ft | 3.3 ft – 5 ft |
| 43” | 5.4 ft – 9 ft | 3.6 ft – 5.4 ft |
| 50” | 6.3ft – 10.4 ft | 4.2 ft – 6.3 ft |
| 55” | 6.9 ft – 11.5 ft | 4.6 ft – 6.9 ft |
| 60” | 7.5 ft – 12.5 ft | 5 ft – 7.5 ft |
| 65” | 8.1 ft – 13.5 ft | 5.4 ft – 8.1 ft |
| 70” | 8.75 ft – 14.6 ft | 5.8 ft – 8.75 ft |
| 75” | 9.4 ft – 15.6 ft | 6.3 ft – 9.4 ft |
| 80” | 10 ft – 16.7 ft | 6.7 ft – 10 ft |
| 85” | 10.6ft – 17.7 ft | 7.1 ft – 10.6 ft |
Speaking of the chart, as you notice, the table above provide a range of distance for screen size. Thus, depend of how large your room is, of course, the smaller bound number is the optimal distance if your budget allow, while the larger bound one is the limit.
Still, those numbers are for perfect 20/20 vision, so depend on you usual situation, a test viewing may be required.
Also as you can see from the chart above, higher picture resolution require shorter viewing distance to keep your eyes from getting strain. However, for the newer 8k TV, that viewing distance become way too close for such a large screen size, thus your viewing area is short of out of range. This is what most people complaining of skipping the hype of getting the 8k TV. But if you’re not on a budget and want a super large viewing area, then an 8k works like a nice treat for any movie session.
On the other hand, it’s totally fine to sit farther away than the recommending distances if you’re only getting a smaller TV as temporal solution. It’s just a little bit wasteful of the high depth picture, but otherwise doesn’t put constrain on anything.
There are other factors that would affecting your viewing enjoyment as well. For instance, if you’re wall-mounting your TV, consider the angle at which it will be. Now this will mostly depend on the type of chair or sofa you’ll be sitting on while watching. Since the recommending distance is measured from the front of the screen to just before your eyes level, this vertical angle will affect and thus reduce/increase as well.
Finally, a test view is always the best to determine whether it’s right or not. Try to place a similarly large poster or picture frame in the position and see if any discomforting exists. If you’re follow the guide above, hopefully you should be able to pick the correct size for your TV viewing distance. Keep in mind, that you can always reposition sitting area and make it closer but not the other ways around though.
