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.

Usable wall means the flat part you can actually cover: leave out skirting, sockets, windows and the enclosure frame.

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

Frequently asked questions

Should my image fill the whole screen?
Close to it, with a small border. An image that spills past the screen edge wastes brightness and looks broken; an image far smaller than the screen wastes the screen you paid for. The step-down figure in the result shows the cost of leaving a border.
16:9 or 4:3 for a golf simulator?
16:9 suits wide rooms and most simulator software. In a low room, 4:3 gives a taller image from the same ceiling, which reads as bigger in a simulator bay. Run both through the tool with your wall and compare diagonals.
How much space do I leave behind the screen?
The screen needs room to give when the ball hits it. Carl's Place's manuals say 6 to 12 inches for standard enclosures and 12 to 16 inches for pro enclosures, depending on swing force. That gap comes out of your room depth, not your wall.
