Golf Simulator Size & Space: Complete UK Planning Guide (2026)

"What size golf simulator do I need?" is the question behind the question. What people really want to know is whether this thing will actually fit in their space — and whether the experience will be good enough to justify the investment.

The answer depends on three things working together: your room dimensions, the equipment you choose, and how you arrange everything within the space. Get any one of those wrong and you end up with a simulator that feels cramped, performs poorly, or both.

This guide is written specifically for UK homes. Every measurement is in metres. Every scenario is based on rooms that actually exist in British houses — not American basements with 3-metre ceilings and space for a full bar beside the hitting bay. If you've already read our room size guide, this article goes deeper into the sizing decisions that come after you've confirmed your room will work: which enclosure size, where to position everything, and how to maximise the space you have.

Understanding Golf Simulator Sizes

A "golf simulator" isn't a single product with a single size. It's a system of components — enclosure, screen, hitting mat, launch monitor, and projector — each with its own footprint. The total size of your simulator depends on which components you choose and how they're configured.

Enclosure sizes available in the UK

Enclosures are the biggest physical component. They provide the frame, side containment, and impact screen that together create your hitting bay. The SimSpace range — our steel-frame enclosures with premium velour-lined interior panels and Platinum triple-layer impact screens — comes in six sizes:

Model	Width (m)	Height (m)	Depth (m)	Best For
SIM 1	3.0	2.5	1.5	Single garages, compact rooms
SIM 2	3.0	2.5	1.5	Standard single garages
SIM 3	3.3	2.5	1.5	Wider garages, dedicated rooms
SIM 4	3.7	2.5	1.5	Double garages, garden rooms
SIM 5	4.0	2.5	1.5	Large dedicated spaces
SIM 6	4.5	2.5	1.5	Premium builds, commercial bays

The depth figure (1.5m) is the enclosure frame depth — how far it protrudes from the wall. Your total room depth needs to be significantly more than this because you also need space for the hitting zone behind the enclosure and clearance behind you for your backswing and launch monitor.

How to read enclosure dimensions

When you see a simulator enclosure listed as "3.0 x 2.5 x 1.5m", that's the frame's external dimensions: width × height × depth. But the usable space inside is slightly smaller because the frame tubes, padding, and screen tensioning hardware all take up space. In practice, you lose roughly 10-15cm on each side internally.

The screen width — the actual projected image area — is typically 20-30cm narrower than the frame width. So a SIM 3 with a 3.3m frame gives you roughly a 3.0m screen width, which is excellent for an immersive projected image.

Total Space Requirements: The Full Picture

Your room needs to accommodate more than just the enclosure. Here's what actually takes up space in a complete simulator setup:

Zone 1: Screen zone (0.3-0.5m from front wall)

The enclosure frame sits a small distance from the wall behind it. You need this gap for two reasons: the impact screen flexes backwards when hit (sometimes 15-20cm on a hard driver swing), and airflow prevents moisture buildup between the screen and wall. Budget 0.3-0.5m for this zone.

Zone 2: Enclosure depth (1.5m)

The enclosure frame itself extends 1.5m into the room. This creates the enclosed hitting bay — the side returns and ceiling baffle that contain stray shots and block ambient light for better projector contrast.

Zone 3: Hitting zone (0.5-1.0m behind enclosure)

Your hitting mat sits behind the enclosure's rear edge. The exact distance depends on where the ball needs to be relative to the screen — typically 2.0-2.5m from the screen surface for a natural feel. Since the enclosure is already 1.5m deep, the mat position is usually 0.5-1.0m behind the frame.

Zone 4: Rear clearance (1.0-2.5m behind hitting position)

Behind your hitting position, you need room for your backswing plus any equipment that sits behind the ball. Camera-based launch monitors like the Foresight GC3S or GC3 sit beside or slightly behind the ball — they need minimal rear space. Radar monitors like the FlightScope Mevo Gen 2 need 1.5-2.5m behind the ball for accurate tracking.

Adding it up

Zone	Camera-Based Monitor	Radar-Based Monitor
Screen gap	0.3-0.5m	0.3-0.5m
Enclosure frame	1.5m	1.5m
Hitting zone	0.5-1.0m	0.5-1.0m
Rear clearance	1.0-1.5m	2.0-2.5m
Total depth	3.3-4.5m	4.3-5.5m

This is the critical sizing calculation. A camera-based setup can work in rooms as shallow as 3.5-4m total depth. A radar-based setup realistically needs 5m or more. If your room is between 4m and 5m deep, your launch monitor choice is the deciding factor — not the enclosure size.

Width: Choosing the Right Enclosure for Your Room

Width is the dimension where you have the most choice, because enclosure sizes range from 3.0m to 4.5m wide. The right enclosure width depends on your room width, but it's not simply "buy the widest one that fits."

Clearance on each side

You need clearance between the enclosure frame and your room walls. A minimum of 15cm on each side allows you to assemble and adjust the frame. Ideally, leave 30cm or more so you can access the sides for maintenance, cable routing, and adjustments.

Room Width	Maximum Enclosure Width	Recommended Model
3.0m	2.7m (tight)	SIM 1 or practice net
3.3m	3.0m	SIM 1 / SIM 2
3.5m	3.2m	SIM 2 / SIM 3
3.7m	3.4m	SIM 3
4.0m	3.7m	SIM 3 / SIM 4
4.5m+	4.0m+	SIM 5 / SIM 6

Why wider isn't always better

A wider screen creates a more immersive projected image, but it also requires a projector with a wider throw ratio, which may mean repositioning the projector or choosing a different model. And if the enclosure is so wide that it leaves less than 15cm clearance to the walls, assembly becomes a nightmare and you can't adjust the frame tension properly.

For most UK single garages at 3.0-3.3m wide, a SIM 1 or SIM 2 is the practical maximum. For double garages at 5.0-5.5m wide, a SIM 4 or SIM 5 gives you a premium experience with comfortable clearance and space for a small seating area beside the hitting bay.

Height: The UK Ceiling Challenge

We've covered low ceiling solutions in detail elsewhere, but height deserves specific attention in a sizing guide because it directly affects which enclosure you can fit.

The SimSpace enclosures are 2.5m tall. Standard UK ceilings in houses are 2.4m. In garages, they're typically 2.3-2.5m depending on construction.

If your ceiling is under 2.5m

A standard SimSpace enclosure won't fit at full height. Your options:

• Remove the ceiling baffle — the top panel of the enclosure. This reduces the effective enclosure height and lets you install the frame posts at their full length, using the ceiling itself as the top containment
• Use a net-based setup — practice nets are shorter and more flexible than rigid frame enclosures. Combined with a quality impact screen hung from the ceiling, this creates a functional hitting bay without the height requirements of a full frame
• Consider a garden room build — if you're building from scratch, specify 2.7-3.0m internal ceiling height. See our garden room guide for specifications

If your ceiling is 2.5-2.7m

A SimSpace enclosure fits, but your swing clearance above the frame is limited. At 2.5m ceiling height with a 2.5m enclosure, you have zero clearance — the frame touches the ceiling. This works, but install foam padding on the top of the frame tubes where they contact the ceiling to prevent marking.

At 2.7m, you have 20cm above the frame. This is comfortable for assembly and allows some overhead clearance for the projector if ceiling-mounted behind the enclosure.

If your ceiling is 2.7m+

You have no height concerns. The enclosure fits with clearance, your swing is unrestricted inside the bay, and you have space for ceiling-mounted projectors and lighting above the frame.

Space Planning for Different UK Rooms

Let's apply these sizing principles to the rooms UK golfers actually have.

UK single garage (typically 3.0 × 5.0 × 2.4m)

What fits: SIM 1 or SIM 2 enclosure with a camera-based launch monitor. Total depth usage: enclosure (1.5m) + hitting zone (0.7m) + screen gap (0.3m) + rear clearance (1.2m) = 3.7m, leaving 1.3m unused at the back for storage or access.

What doesn't fit: Anything wider than a SIM 2 (3.0m frame in a 3.0m room leaves zero side clearance). A radar-based monitor like the Mevo Gen 2 technically fits on depth but leaves minimal rear clearance — position it carefully and it can work, but a camera-based monitor is the safer choice.

Recommended bundle: Foresight GC3S bundle (camera-based, zero rear space needed, fits a SIM 1 enclosure comfortably) or the Mevo Gen 2 bundle if your garage is 5.5m or deeper.

UK double garage (typically 5.5 × 5.5 × 2.4m)

What fits: Almost anything. A SIM 4 (3.7m wide) leaves nearly a metre on each side — enough for a chair, a small table, or a club rack. Any launch monitor type has adequate depth. This is the ideal UK simulator space.

Layout tip: Position the enclosure off-centre, closer to one wall, to create a wider viewing/social area on one side. A 3.7m enclosure placed 30cm from the left wall leaves 1.5m of usable space on the right for seating.

Recommended bundle: Any bundle works here. The Full Swing KIT bundle or Foresight GC3 bundle in a SIM 3 or SIM 4 creates a genuinely premium experience.

Spare room (typically 3.0 × 4.0 × 2.4m)

What fits: A practice net setup with a camera-based launch monitor. The 4.0m depth is too shallow for a full enclosure plus adequate hitting distance. A quality golf net with a launch monitor and tablet/laptop gives you full shot data and course play without the space demands of an enclosure.

What doesn't fit: A full SimSpace enclosure — by the time you add the screen gap, frame depth, and hitting zone, you've used nearly the entire room with nowhere to stand.

Garden room (built to specification)

Recommended internal dimensions: 4.0m wide × 5.5m deep × 2.8m high minimum. This accommodates a SIM 3 or SIM 4 enclosure, any launch monitor type, and comfortable clearance in all directions.

If budget allows, go to 6.0m deep — the extra 0.5m transforms the rear zone from "adequate" to "comfortable" and gives you room for a small bench or stool behind the hitting position. See our planning permission guide for building regulations.

Equipment Footprint Guide

Beyond the enclosure, every component takes up space. Here's the footprint of the equipment in a typical simulator setup:

Component	Floor Space	Notes
Hitting mat	1.5 × 1.5m typical	Sits in the hitting zone, must be on level floor
Launch monitor (camera)	0.15 × 0.15m	Sits beside or just behind the ball — negligible footprint
Launch monitor (radar)	0.15 × 0.15m	Same size, but positioned 1.5-2.5m behind the ball
PC/laptop	0.3 × 0.5m (desk)	Position to one side, accessible but out of the swing path
Projector (ceiling mount)	Zero floor space	Mounted overhead, typically 2.5-3.5m from screen
Projector (shelf/table)	0.3 × 0.4m	Needs stable surface at screen centre height
Side netting (if no full enclosure)	0.3m × room depth	Hangs from ceiling to floor on each side of hitting area

Projector throw distance

The projector needs to be positioned at the correct distance from the screen for its optics. This is called the throw ratio. A short-throw projector (ratio 0.5-0.8) can produce a 3m-wide image from 1.5-2.4m away. A standard throw projector (ratio 1.2-1.5) needs 3.6-4.5m for the same image width.

In most UK simulator rooms, a short-throw projector is essential because standard-throw units can't sit far enough from the screen. The projector is typically ceiling-mounted behind and above the golfer's head, projecting forward onto the screen. Budget this into your depth calculation. Our projector guide covers throw ratios, brightness, and mounting options in detail.

Optimising a Tight Space

Most UK golfers are working with spaces that are adequate but not generous. Here are proven ways to maximise what you have:

1. Choose a camera-based launch monitor

This is the single biggest space-saver. Camera-based monitors like the GC3S, GC3, and Square Golf sit beside or just behind the ball. They need zero depth behind your hitting position. In a 4.5m deep room, that extra 1.5-2m of rear space that a radar monitor would need is instead available for the hitting zone and screen distance.

2. Minimise the screen gap

While 0.3-0.5m is ideal between the screen and wall, you can reduce this to 0.15-0.2m if the wall behind is smooth and flat. The screen will contact the wall on hard shots, so apply foam padding or hang a moving blanket on the wall behind to absorb impact.

3. Use a ceiling-mounted projector

A ceiling mount eliminates the need for a shelf, table, or floor-standing projector behind you. It reclaims that 0.3-0.5m of floor space and keeps cables off the ground. Ceiling mounts are inexpensive (£30-80) and straightforward to install.

4. Consider a thinner hitting mat

Standard hitting mats are 15-25mm thick. If your ceiling is marginal, switching to a thinner mat (10-15mm) gains you an extra centimetre or two of overhead clearance. It's not much, but in a 2.4m ceiling room, every centimetre counts for driver swings.

5. Use the enclosure frame for storage

The SimSpace frame tubes are sturdy enough to support hooks for hanging club towels, headcovers, and even a small shelf for your launch monitor's charging dock. This keeps equipment off the floor and out of your swing zone.

Common Sizing Mistakes

After helping hundreds of UK golfers plan their simulator spaces, these are the mistakes we see most often:

Mistake 1: Measuring to the widest point

Rooms aren't perfect rectangles. A garage might measure 3.3m at the door end but only 3.1m at the wall where your screen goes (due to plasterboard overlap, pipework, or wall irregularities). Always measure at the specific point where the enclosure will sit, and measure at multiple heights — walls can taper.

Mistake 2: Forgetting about the garage door track

If your garage still has a functioning up-and-over or roller door, the track mechanism takes up space along the ceiling and walls. Overhead door tracks can reduce your usable ceiling height by 10-15cm directly above them, and side tracks reduce your usable width by 5-10cm on each side.

Mistake 3: Buying the biggest enclosure that "technically fits"

If your room is 3.3m wide and you buy a 3.3m enclosure, you have zero clearance. Assembly is nearly impossible, you can't adjust the frame, and any slight wall irregularity means the frame won't sit flush. Buy one size down and enjoy the breathing room.

Mistake 4: Ignoring swing arc width

Your club head travels in an arc that extends well beyond your shoulders. A full driver swing arc for an average-height golfer spans roughly 2.5-3.0m from toe to toe of the club head path. If you're swinging inside an enclosure, the internal width needs to accommodate this full arc with clearance. Make sure you're measuring the internal width, not the external frame dimensions.

Mistake 5: Not accounting for the boiler

Many UK garages have the household boiler installed on one wall. Boilers need ventilation clearance (typically 60-100cm clear space around the unit depending on the model and gas safety regulations). This dead zone can't overlap with your enclosure or swing path. Map your boiler clearance zone before choosing an enclosure width or position.

Quick-Reference Size Calculator

Use this to quickly check whether your specific room can accommodate a simulator:

Step 1: Check width

Measure your room width at the enclosure position. Subtract 0.3m (minimum clearance each side = 0.15m × 2). The result is your maximum enclosure width. Match this to the nearest SimSpace model in the table above.

Step 2: Check depth

Measure your room depth wall to wall. Subtract 0.3m (screen gap) + 1.5m (enclosure) + 0.7m (hitting zone). The remainder is your rear clearance. If it's 1.0m or more, a camera-based monitor works. If it's 2.0m or more, any monitor type works.

Step 3: Check height

Measure your ceiling height at the hitting position. If it's 2.5m or more, a standard SimSpace fits. If it's 2.3-2.5m, consider removing the ceiling baffle. Below 2.3m, a net-based setup is the better option.

Step 4: Check for obstructions

Walk the room and note anything that protrudes into the usable space: boilers, fuse boxes, pipework, light fittings, garage door tracks, windows, door swing arcs. Map these onto your layout before ordering.

What If My Space Is Too Small?

If your measurements don't work for a full enclosure setup, you're not out of options. A net-based simulator — quality practice net, camera-based launch monitor, and a tablet or laptop for course play — delivers all the data and gameplay of a full simulator in a much smaller footprint. You lose the big projected image, but you keep the accuracy, the course play, and the ability to practice meaningfully at home.

Our golf net buying guide covers the best options for compact spaces, and our budget simulator guide shows how to build a capable setup from £2,199.

Alternatively, if you're in a position to build a dedicated space, a garden room designed from the start with simulator dimensions solves every sizing problem permanently.

Frequently Asked Questions

What size room do I need for a golf simulator?

The minimum practical room size for a full simulator with enclosure and projector is 3.3m wide × 4.5m deep × 2.5m high. For a comfortable experience with any launch monitor type, aim for 3.7m × 5.5m × 2.7m. A compact net-based setup can work in rooms as small as 2.7m × 3.5m × 2.4m. See our room size guide for detailed dimension requirements by room type.

What is the best golf simulator size for a UK garage?

For a standard UK single garage (3.0 × 5.0m), a SIM 1 or SIM 2 enclosure (3.0m wide) with a camera-based launch monitor is the best fit. For a double garage (5.5 × 5.5m), a SIM 3 or SIM 4 (3.3-3.7m wide) gives you a premium experience with room to spare. Always measure your specific garage — dimensions vary significantly between properties.

How much space do you need behind a golf simulator?

With a camera-based launch monitor (GC3S, GC3, Square Golf), you need 1.0-1.5m behind the hitting position for your backswing clearance. With a radar-based monitor (Mevo Gen 2), you need 2.0-2.5m to accommodate both your backswing and the monitor's position behind the ball. Camera-based monitors are the clear winner for tight UK spaces.

Can I fit a golf simulator in a 3m × 4m room?

A full enclosure with projector is very tight in a 3 × 4m room — the 4m depth barely accommodates the enclosure, hitting zone, and screen gap, leaving no room for a radar monitor and minimal room for your backswing. A better option for this size room is a practice net with a camera-based launch monitor and tablet-based course play. You get the same shot data and gameplay in a space-efficient setup.

What's the difference between golf simulator size and enclosure size?

The enclosure size is just the frame and screen dimensions (e.g. 3.0 × 2.5 × 1.5m for a SIM 1). The total golf simulator size includes the enclosure plus the hitting zone behind it, the screen gap in front, the rear clearance for your backswing and launch monitor, and the footprint of your mat, PC, and projector. A SIM 1 enclosure is 3.0 × 1.5m in floor space, but the total room needed is approximately 3.3 × 4.5m minimum.

Do I need to leave space around the enclosure frame?

Yes. Leave at least 15cm between the enclosure frame and each side wall for assembly access and frame adjustment. Ideally, leave 30cm or more so you can reach behind the frame for maintenance, cable routing, and screen tensioning. At the front, leave 15-50cm between the screen and the wall behind it to allow the screen to flex on impact.

Making Your Decision

Getting the size right is the foundation of a golf simulator you'll use every day rather than one that gathers dust. The process is straightforward:

1. Measure your room accurately — width, depth, and height at the hitting position, not the widest or tallest point
2. Map your obstructions — boiler, fuse box, door arcs, garage door tracks, pipework
3. Calculate your usable space — subtract clearances and obstruction zones from your raw measurements
4. Choose your launch monitor technology — camera-based for rooms under 5m deep, radar-based if you have 5m+
5. Pick the right enclosure — one size smaller than the theoretical maximum for comfortable clearance

Every simulator bundle on our site lists the enclosure size options and space requirements. If you're unsure which size is right for your room, get in touch with your measurements — we've helped hundreds of UK golfers find the right fit for their specific space.
