Viewing 120” closer than 20 ft and you can expect fatigue, eye strain, and or nausea.

If one has to move the eyes or worse, the head to view/cover the whole screen... it is way too big... That WILL cause strain and fatigue.

My theater room was about 17x30 ft and my screen size was 102" if my memory serves me right.

In any case, my preferred spot was roughly the middle of the room or 15 ft from that screen. A 120" screen I would have been watching from the back of the 30 ft room for sure.

For average sized room that is not a dedicated room and is not completely dark and/or is not painted with non reflective wall paint, I would simply get the biggest OLED 4k TV and be completely happy with that.

Projectors have their place but not in a sunlit room full of windows which can not be completely controlled for external light. Nothing worse than paying all that $$$ for a projector and a screen and then watching washed out images that are lacking contrast when a modern OLED 4K TV could have been the answer for much less $$$.

That's just my opinion and I did not go the projector route in my new house. Perfectly happy with a 65" OLED TV, watching from 10 ft away. Perfect.

Serge is pretty spot on with those distances. I thought I'd chime in here since I used to design theaters back in my former days....as far as the projectors go, without getting too detailed, you can break them up into roughly 3 go to brands these days.

1. JVC - known to have the best contrast. JVCs are the go to projectors if you have total or almost total light control since they tend to be slightly less bright than comparable models in other brands. Black levels and shadow details are second to none. Their (now former) 4K shift models can get you very very close to a native 4K projector if it's dialed in properly. The best pure "cinema" projectors. Contrast ratios and natural colors are vivid and look fantastic. Films on a calibrated JVC is the best home theater experience there is.

2. Sony - a close second to the JVCs, not quite the level of shadow detail and blackest blacks but pretty close, tend to be a tad more expensive than the comparable JVCs. Most reviewers see a bit better detail and sharpness in their pictures and their "motion flow" works and looks a bit better than the JVCs version. Colors and contrast are close but not quite up to the JVC level.

3. Epson - Best bang for the buck, comparable models cheaper than the Sonys and JVCs. They tend to have a brighter picture so they seem to work better in more typical family room settings where you don't have total light control. Epsons seem to do nothing wrong but nothing as good as the Sonys and JVCs. If I was designing some type of man cave/room with pool tables etc in a basement with outside windows/lights, using it for viewing sports primarily I may go with an Epson. Have excellent customer service.

Anyone interested in projectors and specifications should look no further than projector central's projector calculator page. It's very detailed and can give you all the throw distances, seating distances and any other thing you need for your particular model:

https://www.projectorcentral.com/pro...ulator-pro.cfm

I've owned 2 Epson, a Panasonic and the JVCs. I've been a JVC owner for the last 9 years and use mine primarily for movies on a cinemascope 2.35:1 screen and it's spectacular.

Default Opinions on Sony short throw projectors


According to that website, viewing distances would be:

Width of your TV or Screen (Not the diagonal length) X 2 = minimum distance

Width of your TV or Screen (Not the diagonal length) X 5 = maximum distance

For a 120 diagonal, the width of a 16:9 screen is 104.6 inches, so...
Minimum distance = 17.4 feet
Maximum distance = 43.6 feet.

My screen size is 116 inches. I sit about 17 feet from the screen. The room is multipurpose music, theater, entertainment. It is not dark or designed as a cave. It has three normal windows but with blinds and/or blackout shades you can make it as dark as you want.

There are a lot of ways to calculate seating distance. Included angle is the best method, with a cross check on visual acuity. This gives you an immersive experience without eye strain or head movement.

SMPTE standard EG-18-1994 recommends a minimum viewing angle of 30 degrees

THX recommends a viewing angle of 36 degrees and an absolute minimum of 26 degrees.

Using the more modern THX recommendations, I sit 12' back from my 106" diagonal 94" wide screen, giving me an included angle of 36 degrees.

I can tell you it is a perfect distance - immersive but not visually fatiguing at all.

For a 120" diagonal screen the THX recommended seating distance is 13.4' (36 degrees) and the maximum is 18.9' (26 degrees)

Sounds like you are in the ballpark. I prefer not to be too close and the THX recommendations are way too close for my taste but it’s a personal preference type of thing.

My HT in pa has a 120 inch screen and the front row is maybe 11 feet away, no eye strain...no issue just a great viewing experience. Honestly anything less than 85 inches is not a theater experience to me.
