I just realized that I should have taken 40% of the 27.72fL to get around 11fL to take into account the 50% drop in brightness after 500 hours + 10% drop due to an anamorphic lens. So the largest I could go on a 1.3 gain screen is an 87 inch 16:9 screen with the Planar. I do want a 2.35 screen so I will need to make sure the area is not more than the area of the 87 inch 16:9 screen. I think even this will be fine since his front row will be about 10 to 12 feet from the front wall, so he will still have a very big screen for the front row. We are planning on him using the front row for blu-ray or high definition stuff and he can move to the 2nd row for standard definition stuff when he and my stepmom are watching it (which should be 90% of the time).
