How to choose a golf simulator projector without the guesswork
Four things decide if a projector works in your simulator: throw ratio, where it mounts, brightness, and the shape of the picture. Here is what each one means in plain words.
A projector that works great in a living room can fail in a simulator. The golfer stands between the projector and the screen. The room is often a garage with light coming in. And the picture has to fill a screen of a set size from a set distance.
1. Throw ratio
Throw ratio is the distance from the projector to the screen, divided by the width of the picture. A lower number means the projector makes a big picture from closer up. A "short throw" projector has a low throw ratio.
Why it matters: you need a picture as wide as your screen from the spot where you can mount the projector. Most projector makers publish a throw calculator. Put in your screen width and your mounting distance before you buy.
2. Where it mounts (and your shadow)
Many home simulators mount the projector on the ceiling, above or just in front of the golfer, so the golfer does not block the light. Some setups put it on the floor in front of the golfer instead. Your ceiling height and the projector's throw ratio decide which places work.
3. Brightness
Brightness is measured in lumens (how much light the projector puts out). A dark room needs fewer lumens. A garage with windows, a gap under the door or bright ceiling lights needs more. If you can make the room dark, you can often use a less bright, less costly projector.
4. Picture shape
Projectors have a native aspect ratio (the shape of the picture, width to height), such as 16:9, 16:10 or 4:3. Simulator screens come in different shapes too. Match the two, or part of the screen will be blank or the picture will spill past the edge.
- What is my screen width, and where can I mount the projector? These two numbers decide the throw ratio you need. Use the maker's throw calculator.
- Will the golfer's shadow fall on the screen? Ask the seller where the projector should sit for your room size and handedness.
- How dark can I make the room? Light in the room decides how many lumens you need.
- Does the projector's native shape match my screen? A mismatch wastes screen space or spills light past the edge.
- Does my simulator software run well on my computer? The projector shows what the computer sends. Check the software's computer requirements too.

Do I need a short throw projector for a golf simulator?
Often, but not always. A short throw projector makes a big picture from close up, which helps in small rooms and lets you mount it where the golfer will not block it. Use your screen width and mounting distance in the maker's throw calculator to check.
Where should a golf simulator projector be mounted?
Most often on the ceiling, above or just in front of the golfer and out of the swing path. Some setups use a floor mount in front of the golfer. The right spot depends on your ceiling height and the projector's throw ratio.
How many lumens does a golf simulator projector need?
It depends on how dark the room is. A dark room needs fewer lumens than a garage with daylight coming in. Making the room darker is often cheaper than buying a brighter projector.
