Media Room Projector Screen Size

I am going to build a new theater room.
Media room projector screen size. If i do that i want the front row to be about 7 5 from the screen which looks good on your room design calculator. Need help calculating the right size projector screen for your needs. However when you watch 16 9 and 4 3 aspect ratio content on your 2 35 1 cinema projection screen you will have black bars on the left and right of the projected image. To put things into perspective a 120 diagonal projection screen is approximately 2 65 meters wide.
If you are purchasing a projector screen for a tv room or primary viewing of hdtv channels and video gaming content then we would suggest a 16 9 projection screen. Use our projector calculator to determine throw distance and optimal screen sized based on your projector. I would like to purchase 4k projector and size the room accordingly for a 120 screen. Use our screen size calculator to determine the viewable area of a screen based on any 1 dimension.
Such a big screen would look out of place in most living rooms which means that you most likely need a dedicated media room to avoid your projector setup getting in the way of daily life. The downside to fixed frame screens is their size. My question is that most content will probably be at 1080p.
