The right number of simulator bays is not the biggest number your space can fit.
It is the number your operating model can support.
A one-bay facility can work. A two- or three-bay facility can work. Four to six bays can work. Seven-bay facilities can work when the model supports them. Eight-plus bays can work.
What fails is the mismatch: too many bays for demand, too few bays for the revenue model, or the wrong layout for the customer experience.
Before signing a lease, the bay-count question should be tied to:
- customer segment
- operating model
- rent
- staffing
- event plan
- league plan
- membership rules
- public access
- food and beverage
- technology and support
- slow-season survival
This article breaks down the common bay-count bands and what each one implies.
One bay
One bay can work when overhead is low and the model is focused.
It fits:
- solo owner-operators
- small markets
- private practice clubs
- instruction studios
- 24/7 access models
- side-income businesses
- spaces with very low rent
The advantage is simplicity. Buildout is smaller, support is simpler, and the owner can keep the model tight.
The downside is fragility.
With one bay:
- one equipment issue shuts down the business
- events are limited
- leagues are hard
- public demand has little room to grow
- every prime-time hour matters
- one bad membership rule can consume too much capacity
One bay is best when the goal is not to become a large venue. It is best when the facility is intentionally small.

Get the playbookTwo to three bays
Two to three bays is the common small-club range.
It fits:
- members-only clubs
- lean hybrid facilities
- instruction-first facilities
- owner-operated businesses
- small markets with limited competition
- facilities that want some capacity without full venue complexity
The upside is balance. Two or three bays give the operator redundancy, more booking options, and some room for lessons or small groups.
The challenge is peak-time scarcity.
If the facility sells too many memberships, every good after-work slot disappears. If it allows too much public booking, members feel squeezed. If it underprices unlimited access, the best customers can accidentally become the least profitable.
Two to three bays can be excellent, but the booking rules have to be disciplined.
Four to six bays
Four to six bays is often the first true facility size.
It can support:
- leagues
- member and public usage at the same time
- small events
- instruction blocks
- better booking variety
- stronger word-of-mouth
- some equipment redundancy
This range works well for hybrid facilities because it creates enough capacity to serve multiple customer types.
But it also changes the cost structure.
More bays mean more:
- buildout
- screens and enclosures
- launch monitors
- computers
- projectors or displays
- networking
- cleaning
- support
- customer instruction
- software complexity
Four to six bays is not automatically safer than two or three. It is safer only if the demand plan, lease, and staffing model can support it.
Eight-plus bays
Eight-plus bays usually means you are building a venue, not just a club.
It fits:
- public-first facilities
- bar-forward venues
- corporate events
- parties
- larger leagues
- high-density markets
- staffed operations
- operators with stronger hospitality systems
The upside is capacity. A larger facility can host events, handle public traffic, and create a more social atmosphere.
The risk is fixed cost.
Eight-plus bays usually require more rent, more buildout, more staff, more marketing, more cleaning, more support, and more working capital. If demand is seasonal, the facility has to survive the months when outdoor golf is competing for attention.
Do not open eight-plus bays just because the space is available. Open eight-plus bays because the business model requires it and the demand plan supports it.
Layout matters as much as bay count
Bay count on paper can lie.
Six cramped bays are not better than four comfortable ones.
Good bay layout should account for:
- right- and left-handed players
- backswing clearance
- screen distance
- seating depth
- bag storage
- food and drink surface
- safe walkways
- ADA pathing
- projector throw
- camera visibility
- emergency exits
- cleaning access
- maintenance access
- sound transfer
Commercial comfort takes more space than a garage simulator.
TrackMan's public simulator specs currently list recommended room dimensions of 15+ feet wide, 10+ feet high, and 18+ feet deep. Treat that 10-foot height as a vendor floor, not a comfort target for every golfer; faster or taller swings may need more ceiling clearance. Design2Golf's PGA-kit planning material cites Proponent Group, a cooperative of PGA professionals, with survey averages closer to 17 feet wide, 22.75 feet deep, and 15 feet high. Those numbers are not universal requirements, but they show the planning reality: a bay that technically fits may still feel tight for real customers.
If your bay count only works with tight clearances, it may not really work.
Bay count by business model
Members-only / private
Typical fit: 1-3 bays
Members-only facilities need enough capacity for members to feel access is worth paying for. Too few bays and the calendar feels crowded. Too many bays and the operator may need more members than the local market can support.
The key question: how many members can the facility serve before prime-time access feels scarce?
Hybrid
Typical fit: 3-6 bays
Hybrid facilities need capacity for both members and public customers. If the facility is too small, public traffic and members fight over the same slots.
The key question: can the calendar protect member value while still leaving enough public inventory to acquire new customers?
Public-first / entertainment
Typical fit: 6+ bays
Public-first venues need enough capacity for groups, events, and peak-time social demand. The model often depends on volume, food and beverage, events, and staff utilization.
The key question: can the venue generate enough traffic to justify the fixed cost?
Bar-forward and event-heavy venues often sit inside this public-first category. They may need 6-10+ bays, but only if staffing, food and beverage, events, and working capital are part of the real operating plan.
Instruction-first
Typical fit: 1-4 bays
Instruction-first facilities can do more with fewer bays because lesson revenue may be higher than simple rental revenue.
The key question: is the bay earning through coaching, practice access, fittings, or public rental?
The capacity math operators should do
Before deciding bay count, model a typical week.
For each bay, estimate:
- available hours
- prime-time hours
- member-only blocks
- public booking blocks
- league blocks
- instruction blocks
- maintenance and cleaning buffers
- expected utilization
Then model revenue by segment:
- memberships
- public hourly bookings
- lessons
- leagues
- events
- food and beverage, if relevant
Finally, model a slow month.
The right bay count is the one that works in a normal month and survives a slow month, not the one that looks best during peak winter demand.
The common mistakes
Mistake 1: fitting too many bays
Operators sometimes try to maximize bay count by shrinking each bay.
That can hurt the experience. Customers notice cramped swings, awkward seating, bad sightlines, and unsafe walkways.
Mistake 2: opening too big
More bays create more revenue potential, but only if demand exists.
If the market is unproven, a smaller opening footprint may be safer than building the dream version immediately.
Mistake 3: opening too small for the model
If the plan depends on leagues, corporate events, and public traffic, one or two bays may not provide enough capacity.
Small can be smart. Small can also be structurally underpowered.
Mistake 4: ignoring support load
Every additional bay adds more things that can break:
- PC
- projector
- launch monitor
- screen
- cables
- software
- mat
- customer confusion
If the facility is unmanned, support load matters even more.
The takeaway
There is no universal right bay count.
Use this as a starting point:
| Model | Common bay-count range | Watch-out |
|---|---|---|
| Private members-only | 1-3 | Prime-time scarcity |
| Hybrid | 3-6 | Member/public conflict |
| Instruction-first | 1-4 | Coach utilization |
| Public-first / entertainment | 6+ | Fixed cost and demand generation |
| Bar-forward/event venue | 6-10+ | Staff, F&B, and working capital |
The best bay count is the smallest number that supports the right business model without making the customer experience feel constrained.
Do not start with square footage.
Start with the model. Then choose the bay count that makes the model work.
