No more than 1".

Based on the geometry I would assume that, if a person had to pick one, having the top/bottom masks further from the screen surface than the side masks would be better?
Or is it the other way around because the top/bottom masks cover more if the image edge?

Close as possible, but try and avoid it touching. Screen fabrics are fragile and having a masking system (especially DIY if that is what you are doing), you should pay added attention to making sure you don't hurt anything.

So is this more for protection than aspect ratio changes? Sorry I am not clear...

I'd guess that having the top/bottom masking as close as possible would be best since those masks span the whole image in front of you, whereas the side masks may move more into peripheral vision (depending on the size screen/viewing distance).

Hmmm...I hope my system works out.
I plan to bevel the side masks to get the edge closer to the screen surface. The beveled side masks will always reside within the sides of the screen frame (not outside) so the beveled edge never needs to clear the screen frame.
Still, that gets me 3/4" to 1" to the screen material at best.
