What is projector throw ratio?

Throw ratio is the relationship between throw distance and image width. It is calculated as Throw Ratio = Throw Distance ÷ Image Width.

How do I calculate image width from throw distance?

Use Image Width = Throw Distance ÷ Throw Ratio. Enter your throw distance and your projector’s throw ratio to estimate the usable screen/image width.

How do I calculate throw distance from screen width?

Use Throw Distance = Image Width × Throw Ratio. Enter your screen width and your projector’s throw ratio to estimate where to mount the projector.

Where do I measure throw distance from?

For best accuracy, measure from the projector lens to the impact screen (not from the back of the projector).

Do short-throw projectors have a common throw ratio?

Many short-throw golf simulator projectors fall roughly around 0.69–0.85, but you should always use the exact throw ratio for your specific projector model.

Golf Simulator Room Size Guide (Ceiling Height, Width & Depth)

Room dimensions diagram for a golf simulator setup

Before you invest in a launch monitor, impact screen, or projector, you need to know one thing: Will a golf simulator actually fit in your room?

This guide covers recommended room width, depth, and ceiling height for a comfortable, realistic golf simulator—plus what to do if your space is on the smaller side.

Ideal Room Dimensions for a Golf Simulator

While setups can vary, a commonly recommended starting point is:

Width: 12–15 ft (10 ft minimum)
Depth: 18–20 ft (16 ft minimum)
Ceiling Height: 9–10 ft (8.5 ft minimum with careful planning)

These dimensions allow:

Full swings with a driver for most golfers.
Centered hitting position relative to the screen.
Room for an enclosure, projector, and launch monitor.

Ceiling Height: The Most Important Factor

Ceiling height often determines whether you can use a driver comfortably indoors. As a general guide:

10 ft – Excellent for almost all golfers, including taller players.
9 ft – Works well for many golfers with good planning.
8–8.5 ft – Tight, may require swing or club adjustments.

Stand in the space and imitate a full driver swing. If you’re close to touching the ceiling, you may:

Limit driver use indoors.
Use a shorter driver or shorter shaft indoors.
Focus on irons, wedges, and fairway woods.

Room Width and Hitting Position

Width affects where you can stand and how centered you’ll be relative to the screen:

12–14 ft width – Allows relatively centered hitting position.
10–11 ft width – May require standing slightly off-center.
Extra width is helpful if both right- and left-handed players will use the simulator.

A slight offset is common in narrower rooms and still works well with a properly aligned screen and aim point.

Room Depth and Layout

Depth determines how far you can stand from the screen, where the launch monitor goes, and where the projector can be mounted.

A typical layout might look like:

Impact screen 12–18 inches from the front wall.
Hitting mat 8–10 ft from the screen.
Projector mounted a few feet behind the hitting area (for short-throw models).

To confirm your projector mounting position, use our throw distance calculator and read our guide on choosing the right projector for your room size .

Projectors That Work Well in Typical Room Sizes

Short-throw projectors are ideal for golf simulators because they can create a large image in limited depth.

BenQ AH500ST – Great for smaller or shallower rooms.
BenQ AH700ST – Versatile choice for standard garages and bonus rooms.
BenQ LK936ST – Ideal for larger, brighter, or premium simulator spaces.

Golf Simulator Room Size FAQ

What is the ideal ceiling height for a golf simulator?

Many golfers aim for at least 9 ft of ceiling height. Ten feet or more is ideal, especially for taller players and full driver swings.

Can I build a simulator in a single-car garage?

Yes, many golfers successfully use single-car garages for simulators. You may need to be thoughtful about screen size, hitting position, and projector placement.

Do I have to stand perfectly centered?

Being perfectly centered is ideal, but in narrower rooms, a slight offset is common and works well when your aim point and screen are aligned correctly.

How deep should my room be?

A depth of 18–20 ft is comfortable for most setups, but you can work with less if you carefully manage hitting distance, projector placement, and launch monitor requirements.

Can Golf HQs help me design my room layout?

Yes. If you send in your room dimensions, we can help you plan a layout and recommend appropriate equipment.
