Golf Simulator Screen Size Calculator
The screen is sized by your wall, not by the projector catalogue. Tell the tool the flat wall you can actually cover and the aspect ratio you want, and it works out the largest image that fits, which side of the wall is the limit, and the standard screen size to buy.
How screen size is calculated
Image height is image width divided by the aspect ratio (16:9, 16:10 or 4:3). The tool takes your usable height after floor and ceiling clearances, compares the height a full-width image would need against it, and keeps whichever is smaller: that is the side the wall limits you on. The diagonal is Pythagoras on the final width and height. Screen classes are Carl's Place's published standard widths, from 7.7 ft up to 18 ft. Cross-check: a 100 inch 16:9 image is 87.2 inches wide, which is the figure BenQ uses in its own throw examples.
Worked examples
The garage wall
13 ft wide, 9 ft high, 16:9, no clearances.
Width-bound: 13 x 7.31 ft image, 179 in diagonal, 13 ft screen class
The low basement
20 ft wide, 8 ft high, 6 in clearances top and floor, 16:9.
Height-bound: 12.44 x 7 ft image. A 4:3 ratio would use the height better
Stepping down
Same garage wall, one class down.
A 12.5 ft class image leaves frame and bungee room the full-width image does not
