Golf Simulator Projector Throw Ratio Guide 2026

What Is Throw Ratio?

Throw ratio is the relationship between the projector distance from the screen and the image width. A 1.0 throw ratio means that for every foot of image width, the projector needs to be 1 foot away. A 0.5 throw ratio (ultra-short throw) means the projector only needs to be half a foot away per foot of image width. Lower throw ratio = projector closer to screen.

Why It Matters for Golf Simulators

A golf simulator typically uses a screen 10 to 14 feet wide. With a standard 1.5 throw ratio projector, you would need the projector 15 to 21 feet behind the screen, which means it would sit behind the golfer and interfere with the swing. Most golf simulators use short-throw or ultra-short-throw projectors mounted above or to the side to solve this problem.

Mounting Options

Ceiling mount directly above the screen is the most common configuration for golf simulators. This requires a short-throw projector (0.6 to 0.9 throw ratio) and a ceiling height of at least 10 feet. Side mount to the left or right works with certain room dimensions. Ultra-short-throw projectors (below 0.4) can mount even closer but tend to be more expensive and have narrower lens shift options.

Recommended Range for Most Setups

For a standard 10x10-foot simulator bay with ceiling mount, look for a throw ratio between 0.6 and 0.8. For a narrower bay, a shorter throw ratio keeps the projector out of the swing path. Always calculate your specific room dimensions before purchasing. Throw ratio x screen width = required throw distance.
