Are there any calculators out there that can calculate horizontal AND vertical FoV based on viewing distance for various scope and 16:9 screen sizes ?

I wouldn’t call it controversial although it is many times here on the forums but it shouldn’t be. It is personal for sure. You have been given a couple recommendations that I somewhat agree with. There was a time in the days of SVGA and XGA and even 720p where pixel size and density played a part in what most people decided was big enough. Many people were using the SMPTE and such specs and they seemed appropriate. Image sizes were limited in more than one way. Resolution along with cinematography along with peoples desires all factored in. Back in the 60’s and 70’s we could go to an IMAX theater and see what the future held because of their very special process that was way ahead of its time. They made images so clear they could push immersion so far beyond anything of the day. They even came up with new cinematography to suit the super immersion, slow pans and keeping items of interest in the central part of the image. It is one of the reason they made their own nature and science movies and limited the length to 45 minutes.
IMO 1080p solved 90% of the issues for immersion for most people and 4k solved the rest of them. Just because you can doesn’t mean you have to with 4k material and 4k IMAX1.89 at least for now will be the top of the immersion food chain. Trouble is everything isn’t 4k and there is a history of great motion pictures that were made before film resolution was anyway close to what they can do today. Directors understood what they had at the time and adjusted their cinematic process to work with the tech of the day.
You can walk into any theater in the country and be confronted with rows and rows of seats to suit the immersion you feel you want. There is no correct seat for everyone but there is a correct seat for everyone.
This is the reason I personally adopted the variable immersion system I use. I have just one row but with my DIY stealth screen wall without any size or AR I’m able to sit in any virtual row in any movie theater from the 1920’s to the latest and greatest IMAX theater of today.
My immersion is personal based on what I’m watching and I have the ability to alter my likes to better suit my guests no different than how I raise or lower the audio level.
The one constant most all of us have our projectors are 16:9 and the most immersive movies we can get at home are IMAX in the 16:9 AR.
I agree there is a bias based around the height or width constraints of the room we are dealt, but I also know with being able to change seating distance most or some of that can be mitigated.
My suggestion is play around with a stealth wall screen for a good long while and if you are like me you will like it. If not you will learn what you like best. Seating style also adds another layer of complexity to the vertical FOV as when you recline it opens your upper limit a lot. With my stealth screen I often shift the image up and down to suit.
Forget about the angles and let your presentations tell you what you like. Then listen to the others you view with and get their input.
