Screen size and picture placement

[hhk27]

I'm planning a sim room and I'm trying to figure out screen size and placement of the projected image. I'll be using a Mevo+ launch monitor.

The wall I'm projecting on is 153" high and 128" wide. Seems to me that 4:3 is the optimal aspect ratio.

4:3 image at 128" wide is 96" high.
16:9 image is 72" high which seems too short.

If I am working with a 128x96 inch image, would you place the bottom of the image at the floor or would you centre it on the wall? I'm leaning towards moving it off the floor at least a bit so that the bottom of the screen where the shot data is would be closer to eye level. How high would you go with it?

If I have 57 vertical inches to fill, I can order a 128x96 impact screen and then surround it with padded panels but what if I get an impact screen made that has a black panel at the top and bottom. Then I don't have to build any sort of enclosure. I can just hang it from the ceiling.

This is all assuming I have that sort of flexibility with my projector. I haven't bought it yet and I haven't done a ton of research on capabilities.

Thoughts?

I've never seen an impact screen with black panels built in. Do these exist?

If you don't do an enclosure, you'll still want to have something up top such as padding on the ceiling or a net. Wedges that hit the screen tend to spin up the screen towards the ceiling. And while your ceiling is high, you have to consider where flop shots are going to be hitting. Will also want something on the side walls if you don't do an enclosure. Shanks will happen.

As far as how high up to start the image, it's all personal preference. I also have blank space to fill on my screen and I start my image about a foot up from the bottom. The bottom of my screen tends to get the most wrinkles because it's free hanging and also because the bottom of the screen is where the highest ball speeds are hitting. So because there's no image down there, I don't have to worry so much about any wrinkles. I can just let it get beat up and not worry about the image being affected.
