How we verify
This category is full of confidently stated numbers that nobody published. We would rather show you a gap than fill it, so here is exactly how the figures on this site are sourced.
Every spec has a source and a date
Each record carries the URL it was read from and the day a human read it. Specs for one product often come from several places, because the price sits on a product page, the placement geometry sits in an installation manual, and software compatibility is published by the software maker rather than the sensor maker. So records carry several sources, and each group of figures says which one it came from.
A shop's number and a maker's number are not the same number
Specialist retailers publish space requirements that the manufacturers simply do not, and that data is genuinely useful, so we carry it rather than pretend it does not exist. But we do not let it do the same work. A figure from the maker can rule a product out of your room. A figure from a retailer can only mark it as tight. Being wrong in that direction would tell you your room is impossible on the strength of a shop's estimate, and that is the wrong error to make.
Empty beats guessed
A dash means the maker does not publish that figure. It never means we could not be bothered. Right now 17 of the 18 launch monitors we track publish no minimum ceiling height at all, which is worth knowing in itself. Any specific ceiling figure you see quoted for those units somewhere else came from a third party.
Where the sensor sits decides the room, not what kind of sensor it is
The usual split is radar against camera. For room fit that split is wrong. Some camera units mount overhead and some sit beside the ball, and at least one radar unit mounts overhead too. What matters is whether the sensor sits behind the ball, beside it, or above it, so that is what we sort and check by.
A ceiling can be too high
Overhead sensors calibrate inside a mount-height band. A ceiling above that band does not rule the unit out, it needs a drop mount to bring the sensor into range, so we mark it as tight rather than as a failure. A ceiling below the band is a genuine no.
The vendor's room figures beat our arithmetic
Where a retailer publishes a minimum room size for a specific package, we use it and say so. They have installed hundreds of these and we have installed none. We only fall back to working it out from the sensor and the enclosure separately when nobody published anything.
Commercial placement and verified specs never merge
Some outbound links earn a commission. No spec, verdict, ranking or table position can be bought, and no arrangement changes a number. Editorial citations link straight to the source with no commercial tagging at all, which is why they look different from the buying links.
The numbers that are ours
Some judgement is unavoidable. A room either physically holds a simulator or it does not, but comfortable is a decision. Rather than blend our standards into the manufacturers’ and let you assume they are all the same kind of number, here is the split. Safety floors can rule a product out. Comfort standards can only ever mark something as tight.
Safety floors
These can rule a product out. They are ours rather than any manufacturer’s, and we publish them as ours.
| Standard | We use | Why |
|---|---|---|
| Minimum ceiling height | 8 ft | Below 8 ft we mark every full-swing product as no fit rather than rank a room that cannot hold a simulator. Retailers who install these describe 8 ft as the absolute floor, with club selection already restricted there. Source, checked 2026-08-25 |
| Minimum ball to screen | 8 ft | The one distance a manufacturer and a retailer state identically. Garmin requires the tee at least 8 ft from the net and FlightScope requires 8 ft of ball flight. Closer than this is a ricochet risk rather than a comfort trade off. Source, checked 2026-08-25 |
| Minimum space behind the ball | 4 ft | Our floor. Nobody publishes one. With less than 4 ft behind the ball you cannot physically complete a backswing. No source, this is ours. |
| Minimum room width | 10 ft | Reachable only with the hitting position offset to one side, which means one handedness only. Source, checked 2026-08-25 |
Comfort standards
These can only ever mark a fit as tight. Missing one means the room works but you will notice it, never that the product will not go in.
| Standard | We use | Why |
|---|---|---|
| Comfortable ceiling height | 9 ft | Our comfort line is 9 ft, not the 10 ft some manufacturers recommend. Four independent sources describe 9 ft as workable, and using 10 ft would mark most real basements as uncomfortable. Source, checked 2026-08-25 |
| Comfortable ball to screen | 10 ft | Ten feet of ball flight is where four sources converge, and it is enough to read the ball off the face before it hits the screen. Source, checked 2026-08-25 |
| Comfortable space behind the ball | 7 ft | Seven feet behind the tee lets you take a full driver swing without shortening it or thinking about the wall. Source, checked 2026-08-25 |
| Screen to back wall | 1 ft | Enclosures need clearance behind the screen for the rear fittings. Carl’s Place requires 8.25 in on a DIY frame and 9.5 in on a Pro frame, and recommends 12 in. Source, checked 2026-08-25 |
| Comfortable width, both handedness | 15 ft | Fifteen feet lets a right handed and a left handed golfer both swing without moving the mat. Fourteen feet is the floor for sharing a room at all. Source, checked 2026-08-25 |
| Comfortable width, one handedness | 12 ft | Twelve feet is comfortable for a single golfer with the tee offset toward their side. Source, checked 2026-08-25 |
What this does not claim
- We have not tested these units. Everything here is read from published documentation and cited, not measured by us.
- We do not publish accuracy tolerances, because with very few exceptions the manufacturers do not either. Where a maker states an accuracy claim we quote it and attribute it rather than turning it into a number of our own.
- Prices move constantly and promotional pricing is common. Treat every price here as the figure on the date shown beside it.
- Products in this category turn over roughly every two years. Where a unit has been replaced we say so on its page rather than quietly removing it.
The oldest record on the site was last checked on 2026-08-25. Every unit’s page lists its own sources and dates. More on why this site exists at all is on the about page, and what happens to anything you type into the calculator is set out in the privacy policy.
