The best aspect ratio for a golf simulator depends on the size and orientation of the screen or projector being used. However, the most common aspect ratio for golf simulators is 16:9, which is the same as a standard HDTV. This aspect ratio allows for a widescreen view that closely resembles the actual view on a golf course. Additionally, a 16:9 aspect ratio provides enough space for important golf simulator features like swing analysis, shot tracking, and virtual caddies.

However, it’s worth noting that some golf simulators may use a different aspect ratio, such as 4:3 or 21:9, depending on the specific software and hardware being used. It’s always a good idea to consult with the manufacturer or a professional installer to determine the best aspect ratio for your specific golf simulator setup.
