Based on your numbers, I assume you're defining "scope" as 2.40:1 (not 2.35:1).

If your height is 43", that would make your width 103" to get a 2.40:1 screen.

103 / 43 = 2.4 (rounded)

Do you remember your Pythagorean Theorem? A squared + B squared = C squared. This would give you a diagonal of 112".

So, if you're projecting a 16:9 Blu-ray to fill the full width of the frame, the image will be 103" wide by 58" tall. (103 / 58 = 1.78)

The difference between 58 and 43 is 15, which means letterbox bars of 7.5 inches each above and below the screen.

Again, all of these numbers are rounded, so the exact amount may be slightly different, but that's approximately what you should expect.

Josh, wow you nailed it. Thanks so much. Would it be advisable to have that 7.5 inches on the top and bottom in black velvet or would a 2 inch trim and black paint be sufficient?

Also I was planning on building a shelving unit to house the equipment and movies underneath the screen. Will the bottom black bar look weird on said shelving?

You're equipment will likely be metal or plastic which will reflect the light back at you creating distraction. top or bottom should be light absorbing as much as possible. If you do put a rack in the path of the light beam, cover it with something like a black curtain or similar.

Well I was going to have tinted glass for the cabinet/shelving doors to avoid that issue along with the power lights as well. The only problem is, I'll have enough space above the screen for the 7.5 velvet area. However the shelving below the screen is going to be fairly close to the bottom of the 2" trim for the screen and it is literally the sensible place to put my equipment and movies as my room is fairly small and no chance in the adjacent room either.

Would this present a problem at all?

Putting the equipment underneath is not a problem, I would personally just put something over the front, like a black curtain, to stop light playing off the equipment and distracting you - that way its still accessible.
