Golf Simulator Room Size Guide: UK Dimensions You Actually Need

"Will it fit in my garage?" It is the single most common question we hear at OpenGolfer, and it is the question that stops more people from pulling the trigger on a golf simulator than any other. The honest answer is: probably yes, but it depends on your specific space, your equipment choices, and how willing you are to make a few compromises.

The problem with most golf simulator room size guides online is that they are written for American audiences. They talk about basement builds with 3-metre ceilings and three-car garages. That is not particularly helpful when you are standing in a single garage in Warwickshire with a 2.4-metre ceiling and a boiler in the corner.

This guide is written specifically for UK homeowners. Every dimension is in metric first. Every room scenario is based on actual British housing stock. And every recommendation comes from years of helping UK golfers set up simulators in real spaces, not ideal ones.

If you are new to the world of home golf simulators, our UK golf simulator buyer's guide covers the broader picture of what you need and what it costs. This article focuses purely on the space question.

Minimum Room Dimensions for a Golf Simulator

Let us start with the numbers. There are three critical measurements for any golf simulator space: width, depth (length), and ceiling height. All three matter, and all three can be the factor that determines whether your setup works or forces you to rethink.

Dimension	Minimum	Recommended	Ideal
Width	3m (10ft)	3.7m (12ft)	4.5m+ (15ft+)
Depth (Length)	4.5m (15ft)	5m (16ft 6in)	5.5m+ (18ft+)
Ceiling Height	2.7m (9ft)	3m (10ft)	3m+ (10ft+)

Width: 3m Minimum, 3.7m Recommended

Width is the measurement from wall to wall, perpendicular to your hitting direction. You need enough room to make a full swing without worrying about clipping a wall, a shelf, or a light fitting on either side.

At 3 metres wide, you can swing most clubs comfortably, but there is little margin for error. Taller golfers or those with very flat swing planes may find it tight. At 3.7 metres, you have a comfortable buffer on both sides, and you also have space for a small seating area or storage without encroaching on the hitting zone.

If your room is narrower than 3 metres, a golf simulator setup is still possible, but you may be limited to shorter clubs or need to adopt a slightly more upright swing. Some golfers happily use spaces as narrow as 2.7 metres with a compact net and launch monitor, accepting that driver swings require extra care.

Depth: 4.5m Minimum, 5.5m Ideal

Depth, or room length, is measured from the hitting position to the impact screen, plus space behind you for the backswing and for your launch monitor if it sits behind the ball. This dimension varies significantly depending on your launch monitor technology, which we cover in detail below.

At 4.5 metres, you can fit a basic setup with a camera-based launch monitor that sits beside or just behind the ball. At 5.5 metres, you have room for radar-based monitors that need to sit further back, plus a comfortable distance between you and the screen for a natural hitting feel.

Ceiling Height: 2.7m Minimum, 3m Ideal

Ceiling height is where things get complicated for UK homeowners, and we dedicate an entire section to it below. The short version: 2.7 metres is workable for most golfers. Below that, you enter a territory of compromise that may or may not be acceptable depending on your height and swing.

Space Requirements by Launch Monitor Type

Not all launch monitors need the same amount of room. The technology inside your launch monitor directly affects how much depth your space requires, and understanding this can mean the difference between a setup that works and one that does not.

Camera-Based Launch Monitors

Camera-based systems such as the Square Golf and Foresight GCQuad use high-speed cameras positioned at or just behind the ball to capture club and ball data at the moment of impact. Because they measure what happens right at the hitting zone, they do not need much space behind the golfer.

This makes camera-based monitors the best choice for tight UK spaces. The Square Golf, in particular, is purpose-built for indoor use and works brilliantly in compact rooms. You can position it just beside or slightly behind the ball, meaning your total depth requirement from the back wall to the screen can be as little as 3.5 to 4 metres.

Radar-Based Launch Monitors

Radar-based systems like the FlightScope Mevo Gen 2 use Doppler radar to track the ball in flight. To do this accurately, they need to be positioned roughly 1.5 to 2.5 metres behind the ball. This additional distance behind the hitting position adds directly to your total room depth requirement.

With a radar-based monitor, your minimum room depth increases to around 5 metres, and ideally 5.5 to 6 metres for optimal performance and a comfortable setup.

Launch Monitor Type	Examples	Position Relative to Ball	Minimum Room Depth	Recommended Depth
Camera-based (overhead/beside)	Square Golf, Foresight GCQuad	At or just behind ball	3.5m (11ft 6in)	4.5m (15ft)
Radar-based	FlightScope Mevo Gen 2	1.5–2.5m behind ball	5m (16ft 6in)	5.5m (18ft)
Photometric (floor-level)	Foresight GC3, Bushnell Launch Pro	Adjacent to ball	3.5m (11ft 6in)	4.5m (15ft)

The takeaway here is straightforward: if your room is on the shorter side, choose a camera-based or photometric launch monitor. If you have plenty of depth, radar-based monitors offer excellent performance and are often more affordable.

UK Room Scenarios: Will Your Space Work?

This is where our guide diverges from every other room size article on the internet. We are not going to talk about American basements or purpose-built commercial bays. We are going to talk about the spaces that real UK homeowners actually have available.

Typical UK Single Garage

Typical dimensions: 2.4m high x 3m wide x 5m deep (7ft 10in x 10ft x 16ft 6in)

Verdict: Yes, with modifications

The single garage is by far the most common location for UK golf simulator installations, and the good news is that it works. The width of 3 metres is at the minimum threshold but is perfectly adequate for most golfers. The depth of 5 metres gives you enough room for a screen, hitting area, and a camera-based launch monitor.

The challenge is the ceiling. At 2.4 metres, a standard UK single garage is below the recommended minimum for a full driver swing. However, thousands of UK golfers use simulators in garages at this height. We cover the ceiling height workarounds in detail below.

What works in a single garage:

• Camera-based launch monitor (Square Golf is the top choice here)
• Compact enclosure or hitting bay with impact screen
• Short-throw projector mounted on the ceiling or a shelf
• Mat positioned 2 to 2.5 metres from the screen

What does not work:

• Radar-based monitors unless the garage is deeper than average
• Full unrestricted driver swings for golfers over 185cm (6ft 1in) without ceiling modification
• Side-by-side seating area (not enough width)

Recommended setup: A Square Golf bundle with a SimSpace compact enclosure gives you the best experience in a single garage. If your garage is a few inches taller than standard, or if you are willing to add ceiling padding, you are well within comfortable territory. Our guide to building a golf simulator in your UK garage covers the full process.

Typical UK Double Garage

Typical dimensions: 2.4m high x 5.5m wide x 5.5m deep (7ft 10in x 18ft x 18ft)

Verdict: Ideal

A double garage is the sweet spot for a UK golf simulator. You have ample width for a full swing with room to spare, enough depth for any launch monitor type, and space beside the hitting area for seating, storage, or even a small bar setup.

The only limitation remains the ceiling height at 2.4 metres, but the generous width and depth mean you can position everything optimally and focus your efforts on solving the ceiling challenge alone.

What works in a double garage:

• Any launch monitor type, including radar-based systems
• Full-size enclosure with side panels and ceiling baffles
• Long-throw or short-throw projector with optimal throw distance
• Comfortable viewing area beside the hitting zone
• Storage for clubs, accessories, and equipment

Recommended setup: A FlightScope Mevo Gen 2 bundle or a Square Golf bundle with a full-size SimSpace enclosure. You have the space for a premium experience here, so invest in a quality screen and projector to make the most of it.

UK Spare Bedroom

Typical dimensions: 2.4m high x 3m wide x 4m deep (7ft 10in x 10ft x 13ft)

Verdict: Tight but possible with a compact setup

Spare bedrooms in UK homes are notoriously small, and a 3m by 4m room is fairly typical. The depth of 4 metres is the limiting factor here. You will not have room for a radar-based launch monitor, and even with a camera-based system, the distance between your hitting position and the screen will be modest.

That said, a practice-focused setup works well in a spare bedroom. If you are primarily looking to work on your swing, dial in your distances, and play the occasional virtual round, a compact net and launch monitor setup is perfectly viable.

What works in a spare bedroom:

• Camera-based launch monitor with a compact hitting net
• Practice net rather than a full enclosure with projector
• Foam or restricted-flight balls for safety
• Portable mat that can be moved when the room is needed for other purposes

What does not work:

• Full enclosure and projector setup (not enough depth for comfortable viewing)
• Radar-based launch monitors (not enough space behind the ball)
• Permanent installations if the room needs to serve other functions

Recommended setup: A Square Golf unit paired with a quality practice net. You get full shot data, course play on your tablet or laptop, and a setup that packs away when guests visit. For more detail on what this costs, see our golf simulator cost guide for the UK.

Loft Conversion

Typical dimensions: Varies significantly. Ridge height may reach 2.7m+ but eaves drop to under 1.5m.

Verdict: Check your ridge height and usable floor width carefully

Loft conversions can work well for golf simulators, but the sloped ceiling creates unique challenges. The ridge height at the centre of the room might be 2.7 metres or more, which is excellent, but the usable width where the ceiling is high enough for a full swing may be quite narrow.

Measure the width of the floor area where the ceiling is at least 2.4 metres high. If this width is 3 metres or more, and the room has adequate depth, a simulator setup is viable. Position your hitting mat directly under the ridge line where the ceiling is highest.

Key considerations for lofts:

• Floor strength: golf simulators with enclosures and mats add significant weight. Consult a structural engineer if you are unsure whether your loft floor can handle the load
• Noise: impact sounds travel downward through loft floors. Add sound insulation beneath the hitting mat
• Access: getting a large impact screen and frame up a loft ladder or narrow staircase can be challenging. Measure your access route before ordering

Garden Room or Outbuilding

Typical dimensions: Built to specification, commonly 3m high x 4m wide x 6m deep (10ft x 13ft x 20ft)

Verdict: The best option if you are building from scratch

A purpose-built garden room is the gold standard for a UK golf simulator. You control every dimension, you can specify the ceiling height you want, and you avoid disrupting your home's living space.

When commissioning a garden room for a golf simulator, specify a minimum internal ceiling height of 2.7 metres, ideally 3 metres. This solves the ceiling problem that plagues every other UK room type. Ensure the internal width is at least 3.7 metres and the depth is at least 5 metres.

What to specify for your garden room build:

• Internal ceiling height of 3 metres (not external roof height, which includes insulation and roofing material)
• Internal width of 3.7 metres minimum
• Internal depth of 5.5 metres for maximum flexibility
• Electrical supply with dedicated circuits for projector, launch monitor, PC or tablet, and lighting
• Insulation to R-value standards suitable for year-round use in UK climate
• Level, solid floor suitable for a hitting mat (concrete slab or engineered timber)
• Adequate ventilation or climate control

Our comprehensive golf simulator garden room guide covers planning permission, build specifications, electrical requirements, and recommended garden room suppliers in detail.

The Ceiling Height Problem: A UK-Specific Challenge

If there is one dimension that causes more headaches than any other for UK golf simulator owners, it is ceiling height. And there is a very specific reason: the standard UK ceiling height is 2.4 metres (7 feet 10 inches).

Most American golf simulator guides recommend a minimum ceiling height of 2.7 metres (9 feet), and many suggest 3 metres (10 feet) as ideal. That is because standard American residential ceilings are 2.4 to 2.7 metres, and basements, which are the most common simulator location in the US, often have even more headroom after finishing.

In the UK, 2.4 metres is what you get in most houses, most garages, and most garden rooms unless you specifically request otherwise. So what do you do?

Can You Use a Golf Simulator With a 2.4m Ceiling?

Yes. Thousands of UK golfers do exactly this. But you need to be realistic about the limitations and take steps to protect both yourself and your ceiling.

The maths: A golfer who is 180cm tall (5ft 11in) with arms extended and a driver in hand reaches approximately 2.6 to 2.7 metres at the top of the backswing. In a 2.4-metre room, this means the club head contacts the ceiling during a full driver swing.

Practical workarounds:

• Shorten your backswing slightly. Many golfers find that a three-quarter backswing produces nearly identical distances on a simulator while keeping the club safely below the ceiling. After a few sessions, a slightly restricted backswing feels completely natural indoors
• Use ceiling padding. Install foam padding tiles on the ceiling above your hitting area. This protects both the ceiling and your club if you catch it on the upswing. Acoustic foam panels or interlocking gym mat tiles fixed to the ceiling work well and cost very little
• Choose shorter clubs for practice. Irons and wedges are comfortably usable at 2.4 metres for the vast majority of golfers. If your primary goal is to sharpen your short game and iron play, ceiling height is not a significant issue
• Lower your hitting mat. If your floor allows it, a recessed or thinner hitting mat gives you an extra couple of centimetres. Some golfers remove floor coverings in their garage and hit directly off a mat placed on the concrete slab
• Consider your height. Golfers under 175cm (5ft 9in) often find that 2.4 metres is perfectly workable even with a driver. Taller golfers may need to adopt the restricted backswing approach or focus on irons

Ceiling Height and Launch Monitor Compatibility

Some launch monitors handle low ceilings better than others. Camera-based systems that sit at floor level or just behind the ball are generally unaffected by ceiling height. Overhead-mounted systems obviously need adequate clearance for installation plus the camera's field of view.

Ceiling Height	Golfer Height Limit (Full Driver Swing)	Recommended Approach
3m+ (10ft+)	Any height	Full unrestricted setup, no compromises needed
2.7m (9ft)	Up to 185cm (6ft 1in)	Full setup, ceiling padding recommended as precaution
2.4m (7ft 10in)	Up to 170cm (5ft 7in) for full swing	Three-quarter backswing for taller golfers, ceiling padding essential, irons and wedges unrestricted
Below 2.4m	Very limited	Chipping and putting practice only, or net-based setup without full swings

Setting Up Your Specific Space

Once you have confirmed that your room meets the minimum dimensions, the next step is planning exactly where everything goes. A well-planned layout maximises usable space, improves the simulator experience, and avoids the frustrating discovery that your projector does not quite fit where you expected it to.

How to Measure Your Room Properly

Do not rely on estate agent floor plans or building plans for your measurements. They are frequently inaccurate, sometimes by as much as 10 to 15 centimetres, which matters when you are working with tight tolerances.

1. Use a laser measure. A basic laser distance measure costs under twenty pounds and gives you accuracy to the millimetre. Measure at multiple points, as walls are not always parallel and ceilings are not always level
2. Measure width at the hitting position. Measure the clear width at the point where you will stand to hit, not at the widest point of the room. Account for any protruding shelves, pipes, or fuse boxes
3. Measure depth from the screen wall. Start at the wall where your screen will be mounted and measure back to the rear wall. This is your total usable depth
4. Measure ceiling height at the hitting position. If your ceiling is not level (common in garages with a slight slope for drainage), measure at the exact spot where you will swing. This is the measurement that matters
5. Check for obstructions at swing height. Light fittings, exposed beams, garage door mechanisms, pull cords, and smoke detectors can all interfere with your swing. Note anything that protrudes from the ceiling or walls within the swing zone

Account for Room Features

UK garages and utility spaces are full of things that eat into your usable dimensions. Before finalising your layout, identify and plan around these common obstacles:

• Boiler and pipework: If your boiler is in the garage, it needs clearance for ventilation and servicing access. You cannot mount a screen directly over a boiler. Plan your screen position to avoid it entirely
• Consumer unit (fuse box): Must remain accessible at all times. Do not block it with an enclosure frame
• Door swing: Internal doors into the house, side doors, and the garage door itself all need clearance to open. A door that opens into your hitting zone is a safety issue
• Electrical sockets and switches: Note the position of every socket. You will need power for your projector, launch monitor, computer or tablet, and potentially lighting. Plan cable runs to avoid trip hazards across the hitting area
• Windows: If your space has windows, consider whether they need protection from stray balls. An enclosure with side returns solves this, or you can add protective netting

The Ideal Room Layout

For a standard simulator setup with an impact screen and projector, plan your room in three zones from front to back:

1. Screen zone (0.3m from front wall): Your impact screen and enclosure frame sit here. Leave a small gap between the screen and the wall to absorb screen movement on impact and to allow airflow if a projector is mounted behind or above
2. Hitting zone (2 to 2.5m from the screen): This is where your mat and launch monitor sit. The distance from mat to screen affects the visual experience and ball flight capture. Two metres is a comfortable minimum; 2.5 metres feels more natural and gives the ball slightly more flight time before impact
3. Rear zone (behind the hitting position): Space for your backswing, your launch monitor if it sits behind the ball, and ideally a step or two of clearance behind you. If using a radar-based monitor, this zone needs to be 1.5 to 2.5 metres deep

Equipment Recommendations by Room Size

Once you know your room dimensions, you'll need to choose the right components to fit. Our enclosure size guide matches enclosures to typical UK room widths, and our hitting mat guide covers which mat sizes work best for different spaces.

Your room size should drive your equipment choices, not the other way around. Buying a setup that does not fit your space leads to a poor experience, wasted money, and equipment gathering dust. Here is what we recommend based on the three most common space categories.

Small Room: Under 3.5m Wide or Under 4.5m Deep

In a compact space, prioritise accuracy and practicality over visual spectacle. A high-quality launch monitor paired with a durable practice net gives you outstanding data, realistic gameplay on a tablet or laptop screen, and a setup that fits comfortably without cramming.

Recommended equipment:

• Square Golf launch monitor bundle: compact design, sits beside the ball, and delivers accurate data in tight spaces
• Quality practice net with ball return
• Hitting mat: 1.5m x 1.5m is sufficient
• Tablet or laptop for course play and data display

This setup works in spare bedrooms, small single garages, and any space where a full enclosure simply will not fit. Do not underestimate it: the data quality from a good launch monitor is identical whether you are hitting into a net or a screen.

Medium Room: 3.5m to 4.5m Wide, 4.5m to 5.5m Deep

This is the most common scenario for UK golfers and covers the majority of single and double garages. You have enough space for a full enclosure with an impact screen and projector, creating the immersive experience that most people picture when they think of a home golf simulator.

Recommended equipment:

• Square Golf bundle or FlightScope Mevo Gen 2 bundle (depending on room depth)
• SimSpace enclosure in the size that matches your room width
• Short-throw projector, ceiling-mounted behind the hitting position
• Premium hitting mat: 1.5m x 1.5m or larger
• Side netting or enclosure side returns if the room is wider than the screen

This is the configuration that delivers the best balance of experience and value for most UK golfers. You get projected course visuals, full ball flight data, and a dedicated space that feels like a proper simulator bay.

Large Room: 4.5m+ Wide, 5.5m+ Deep

With a large space, whether a double garage, a large garden room, or a dedicated outbuilding, you have the luxury of choosing any equipment combination without compromise. This is where you can create a genuinely premium setup.

Recommended equipment:

• Choice of any launch monitor, including radar-based systems that need more depth
• Full-size SimSpace enclosure with side returns and ceiling baffles
• High-quality 1080p or 4K projector with optimal throw distance
• Premium hitting mat with a larger footprint
• Comfortable seating or viewing area beside the hitting zone
• Additional lighting, sound system, or display screens for data

Explore our full range of golf simulator bundles to find the right combination for your space and budget.

Common Mistakes to Avoid

After helping hundreds of UK golfers set up their simulators, we see the same mistakes repeated. Save yourself the frustration by avoiding these pitfalls:

• Buying before measuring. It sounds obvious, but we regularly speak to customers who have purchased a full enclosure only to discover it does not fit. Measure twice, buy once
• Ignoring ceiling height. Many golfers focus on floor dimensions and forget to check the ceiling. A room that is 5 metres long and 4 metres wide sounds perfect until you realise the ceiling is 2.2 metres and your driver contacts it every swing
• Choosing a radar-based monitor for a short room. If your room depth is under 5 metres, stick with a camera-based launch monitor. A radar unit that cannot sit far enough behind the ball will give inconsistent readings
• Forgetting about the projector. Your projector needs to be mounted at the correct distance from the screen for its throw ratio, typically 2.5 to 3.5 metres for a short-throw unit. This distance comes from your total room depth. Factor it in during planning
• Not accounting for the enclosure frame depth. Enclosure frames add 15 to 30 centimetres to the front of your setup. Your usable hitting depth is your room depth minus the enclosure frame depth minus the gap behind the screen

Frequently Asked Questions

What is the minimum room size for a golf simulator?

The absolute minimum room size for a functional golf simulator is 3 metres wide, 4.5 metres deep, and 2.4 metres high (10ft x 15ft x 7ft 10in). At these dimensions, you need a camera-based launch monitor, may need to restrict your driver backswing slightly, and a net-based setup will be more practical than a full enclosure with projector. For a comfortable projected simulator experience, aim for 3.7 metres wide, 5 metres deep, and 2.7 metres high.

Can I use a golf simulator in a garage?

Yes, and the garage is the most popular location for golf simulators in the UK. A standard UK single garage at 3m x 5m is large enough for a compact simulator setup with a camera-based launch monitor. A double garage at 5.5m x 5.5m is ideal and accommodates any launch monitor type and a full-size enclosure. The main challenge in UK garages is the standard 2.4-metre ceiling height, which may require a shortened backswing for taller golfers hitting driver. Read our full guide to building a golf simulator in a UK garage for step-by-step instructions.

What ceiling height do I need for a golf simulator?

The recommended minimum ceiling height is 2.7 metres (9 feet), which allows most golfers to make a full swing with a driver. However, the standard UK ceiling height of 2.4 metres (7ft 10in) is workable with modifications. Install ceiling padding, use a three-quarter backswing with longer clubs, and consider that irons and wedges are generally fine at this height for most golfers. If you are building a new space such as a garden room, specify a minimum internal ceiling height of 3 metres for an unrestricted experience.

How far should I stand from the golf simulator screen?

The recommended distance from your hitting position to the impact screen is 2 to 2.5 metres (6ft 6in to 8ft). Standing closer than 1.5 metres makes the projected image feel unnaturally close and can cause ball ricochet issues. Standing further than 3 metres wastes depth and may place you too far from the projected image for comfortable viewing. Most golfers find 2 to 2.5 metres to be the sweet spot for both safety and visual immersion.

Do I need planning permission for a golf simulator garden room in the UK?

In most cases, a garden room for a golf simulator falls under permitted development and does not require planning permission, provided it meets certain conditions: it must be single storey, not cover more than 50 per cent of the garden, not be forward of the front of the house, and the eaves height must not exceed 2.5 metres (or 3 metres for a dual-pitched roof, away from boundaries). However, rules vary and you should always check with your local planning authority. Conservation areas, listed buildings, and certain other designations have stricter rules. Our golf simulator garden room guide covers planning considerations in full.

Can I fit a golf simulator in a spare bedroom?

A typical UK spare bedroom at 3m x 4m with a 2.4m ceiling can accommodate a compact golf simulator setup, but you will need to set realistic expectations. A practice net and camera-based launch monitor work well in this space, giving you full shot data on a tablet or laptop. A full enclosure with projector is unlikely to fit comfortably. If the room needs to serve dual purposes, choose portable equipment that packs away easily.

What is the best golf simulator for a small room in the UK?

For small UK rooms, a camera-based launch monitor is the best choice because it requires minimal depth behind the ball. The Square Golf system is specifically designed for compact indoor spaces and delivers excellent accuracy. Pair it with a quality practice net for the most space-efficient setup, or with a compact enclosure if you have just enough room for a projected experience. See our UK buyer's guide for detailed comparisons.

Summary: Your UK Room Size Checklist

Before you commit to a golf simulator purchase, run through this quick checklist:

1. Measure your space accurately with a laser measure: width, depth, and ceiling height at the hitting position
2. Check for obstructions: boiler, fuse box, door swings, low beams, light fittings, pipes
3. Match your launch monitor to your depth: camera-based for rooms under 5m deep, radar-based only if you have 5m or more
4. Address the ceiling: if under 2.7m, plan for ceiling padding and a potentially restricted backswing with driver
5. Plan your layout: screen zone, hitting zone, and rear zone must all fit within your depth
6. Choose equipment that fits: do not buy a 4-metre wide enclosure for a 3.5-metre wide room
7. Budget for the space, not just the simulator: flooring, padding, lighting, electrical work, and climate control all cost money

Room size does not have to be a barrier to owning a golf simulator. The vast majority of UK homes have at least one space that works, whether it is a garage, a spare room, a loft, or a garden room. The key is understanding your specific dimensions, choosing equipment that suits your space, and being realistic about any compromises.

If you are unsure whether your space will work, get in touch. We have helped golfers across the UK set up simulators in spaces ranging from compact single garages to purpose-built garden rooms, and we are happy to review your measurements and recommend the right setup for you.
