Your photo doesn't do your screen justice, at first it looked like it was around 70''. And then I realized that your ceiling is actually quite tall. And your screen may be placed a bit too closed to the ground for my taste. I like looking a bit higher than my eyes, just like at a cinema
I have 9 foot ceilings.
Old cinemas maybe. Most every theater in our area is now stadium style seating so you no longer have to crane your neck back to see it.
Everyone has a personal preference here and I would never assume to tell someone how they should watch. But the issue for you is more going to be running out of room. From where you want to place your projector you are going to be butting up against your ceiling or actually hitting your ceiling. I would strongly consider buying a ceiling mount. If you like your screen higher you won’t even need much of a drop tube. It will get the projector up out of the way, get your furniture out of the light path, and get the heat/noise away from your head.
