Golf Simulator Ball Position and Stance: Setup by Device

A simulator asks you to place the ball correctly twice. The first placement is the one golf instruction has always covered: where the ball sits between your feet for the club in your hand. The second is where the ball sits relative to the launch monitor, and that one decides whether the unit reads the shot at all and how accurately it does so.

For most players the working answer is short. Put the ball on the sensor's marked spot, then build your stance around it. The driver goes inside your lead heel, wedges sit near the middle of your stance, and your feet do the moving rather than the ball. The rest of this page explains why that approach holds up, what each device class expects, and how to read setup errors from the numbers you get back.

How we put this together: we compared published manufacturer specs, retailer listings and owner reports. Links on this page may earn us a commission.

Two placements to get right before every session

The first placement is the ball's position relative to your feet for the club you are holding. It is the same idea as outdoors, and it drives strike quality, launch and direction. Get it wrong and you will hit a poor shot on any surface, simulator or not.

The second placement is the ball's position relative to the launch monitor. This one is specific to indoor practice. It decides whether the unit sees the ball at all, and how cleanly it reads the flight once it does. A stance that looks perfect on the wrong spot still produces a missed or doubtful read.

When the two placements conflict, keep the ball where the sensor needs it and move your stance instead. The sensor's requirement comes from the hardware, while your stance can adjust by a few inches in either direction without changing the fundamentals of your swing.

Each manufacturer publishes its own placement guide, and that guide overrides any general figure on this page. If a number here disagrees with your manual, follow the manual and treat this page as background reading.

Everything here comes from researched guidance in maker documentation and common instruction. Our site has not run placement trials, so read the distances below as starting points rather than verified targets.

Your launch monitor's placement guide comes first

The guide usually lives in one of three places: the quick start card in the box, the setup screen in the companion app, or the support section of the maker's website. Check it again after firmware updates, because makers sometimes revise placement advice when they change how a unit reads the ball.

The table below groups common devices by how they are mounted. Use it to find your device class, then confirm the exact figures in your own manual.

Device class	Examples	Where the unit sits	Typical published guidance (check your manual)	Left-handed note
Side-mounted camera	SkyTrak+, Foresight GC3 and GCQuad, Bushnell Launch Pro, Uneekor EYE MINI	Beside the ball, facing it	Ball on a marked spot or laser dot, roughly 2 ft from the unit for many models (about 22 in is often quoted)	Unit moves to the other side
Rear radar	Trackman 4, FlightScope Mevo+ and X3, Garmin Approach R10	Behind the golfer, looking down the target line	A set distance behind the ball, often several feet; 6 to 8 ft is commonly quoted, and about 8 ft is cited for the Mevo+ indoors	Usually no move needed
Overhead	Uneekor EYE XO2 and QED, Foresight GCHawk, TruGolf Apogee, Trackman iO, ProTee VX	Ceiling above or slightly ahead of the ball	A marked hitting zone under the unit; the Apogee is listed at about 9 to 10 ft high and about 22 in forward of the ball	Usually handled in software
Phone-sized camera and radar	Rapsodo MLM2Pro and similar	Behind the ball on the target line	Follow the app's guidance on distance and alignment	Usually no move needed

Once the unit is in place, level it if the maker asks you to. Some apps include a level screen that makes this a quick job. A unit sitting slightly off level can shift the read zone enough to change spin figures, so it is worth the check every time the unit has been moved.

Why the sensor spot is not negotiable

A camera unit sees a fixed field of view. A ball outside that field may not register at all, or it may register with poor edge detail, which makes spin and launch estimates less reliable. The unit's software assumes the ball sits in a particular part of the frame, and it has no way to correct for a ball that wanders out of that part.

Radar units work on a different principle, but they have their own expectations. They need the ball at the expected distance and on the expected line to pick up the launch cleanly. A ball placed too far to one side can read as a different shot, and a ball placed at the wrong distance can change how the unit tracks the club and ball together.

Overhead units read a defined zone on the mat. Outside that zone, reads degrade, and the degradation is often subtle. You might see a shot register with numbers that look plausible but drift from what the ball actually did. That is harder to notice than a missed read, and it is one reason to keep the ball on the marked spot every time.

Where side cameras go wrong when the ball drifts

Side units are the most sensitive to small placement errors because the ball's position relative to the lens changes how the lens sees it. A ball a few inches off the marked spot can produce different numbers from the same swing, and the difference is easy to blame on the club or the swing. The fix is simple but easy to skip: put the ball on the spot every time, even for a short chip you think will not matter.

Why radar and overhead units tolerate a different setup

Rear radar units sit behind the golfer, so they see the shot from the same general direction the ball travels. That gives them a more forgiving geometry for a side-to-side error than a side camera has. Overhead units are the opposite: they depend on the hitting zone under them, so the zone is the constraint, not the golfer. Knowing which constraint your unit cares about tells you where to spend your attention during setup.

Fix the ball, then move your feet

Most setup problems come from the ball moving around while the golfer searches for a comfortable stance. Reverse that order. Lock the ball first and let the stance follow. The steps below apply to every club, and they take about as long as setting a tee.

Mark the sensor's ball spot on the mat with tape or a dot. For side units, use the laser or marker the unit provides.
For each club, set the ball on that spot first.
Build your stance around it. For a driver, your lead heel lines up with the ball. For a wedge, the ball sits near the centre of your stance, so your feet shift toward the target relative to the ball.
The ball never leaves the read zone, and its position in your stance still changes club by club.
If you like visual guides, mark two or three foot positions on the mat with small tape marks.

The result is a setup that satisfies both placements. The ball stays where the sensor expects it, and your stance does the work of matching the club. Players who skip the first step often end up with a stance that looks right and a read zone that quietly disagrees.

Keeping stance width consistent across clubs

Stance width changes with the club: wider for the driver, narrower for wedges. Once the ball is fixed, the stance is the variable. Tape marks at two widths, one for long clubs and one for short, make the adjustment repeatable. Without them, stance width tends to drift over a session, and the ball's relationship to your body changes without you noticing.

Ball position by club, as most coaches teach it

Teachers vary on the exact figures, and players with very different builds or swings may need small changes. Treat the table below as the common teaching reference, and ask a coach to personalise it if your ball flight is consistently off.

Club	Ball position in stance	Stance width	Tee height or lie
Driver	Inside the lead heel	Widest, about shoulder width or a little wider	Teed so about half the ball sits above the crown at address
Fairway woods and hybrids	A ball or two inside the driver position	Slightly narrower than the driver	Off the mat or a very low tee
Long and mid irons	A little forward of centre	About shoulder width	Off the mat
Short irons and wedges	About the centre of the stance	Narrower	Off the mat
Putter	Just forward of centre, with your eyes over or just inside the ball	Narrow and balanced	Your normal putting setup

Right-handers set the lead heel as the left heel, and left-handers mirror everything. For side-mounted units, mirroring also means moving the unit to the other side of the ball, which the handedness section below covers in more detail.

Find a mat with alignment marks

Lining up body, mat and sensor on one target line

Indoors there are no trees or fairway edges to aim at, so alignment needs deliberate markers. The room gives you walls and a screen, and neither is a reliable reference for where the ball should start. You have to build the target line yourself, running from the ball spot toward the centre of the screen, and then make three things point the same way.

Those three things are the launch monitor, the hitting mat and the software's target. If any one of them is off, you can hit a well-struck shot and still see a miss on the screen. A common mistake is to aim the body carefully and then forget to check whether the unit and the software agree with it. Work through the device steps first, then the body steps.

Aiming the device

Set the mat square to the screen centre, then tape a line from the ball spot toward the centre of the screen.
Align the unit to that line using its alignment method. On the SkyTrak+, the laser dot and the app's alignment tools do this job. Radar units are aimed at the target. Check your manual for the exact method on your model.
Confirm the software's target matches the screen centre. Many programs let you adjust an aim offset, and the exact options vary by platform, so check your software's documentation before you change anything.

Why the tape line matters more than the screen

The screen is a moving image, and the projected picture can sit slightly off centre in the room. The tape line is fixed to the floor, so it stays put between sessions. Aligning to the tape keeps the device and the mat consistent even if you move furniture or adjust the projector. It also makes a miss easier to diagnose, because you know the reference did not change.

Aiming yourself

Lay one alignment stick on the target line just outside the ball.
Lay a second stick parallel to it, along your toes.
Set your feet, hips and shoulders parallel to the target line. For a right-hander, that means the body aims slightly left of the target.
Check the path number if your unit measures it. An open stance, with feet aimed left for a right-hander, tends to encourage an out-to-in path. A closed stance tends to encourage an in-to-out path.

The open and closed stance effects are tendencies rather than rules. The path number tells you what your swing is actually doing, so use it to judge the setup instead of relying on the stance alone. Pull the sticks away from the ball's path before you swing, so they do not sit in the sensor's view.

A two-minute setup routine

Run through this before your first shot each session. It catches the problems that cause the most confusing data, and it takes about two minutes once the routine is familiar.

Check the unit has not moved, and re-level it if needed.
Check the mat has not shifted relative to the tape marks.
Clean the ball and the hitting area, and remove extra balls and tees from the sensor's view.
Set the ball on the spot, and set your stance for the club.
Hit three easy wedge shots and check the readings for consistency before moving to longer clubs.
Repeat the quick check whenever you switch between left- and right-handed players.

If the three wedge shots return scattered numbers, stop there and work through the symptom table below before you reach for the driver. Fixing a setup problem on short shots is far quicker than chasing it through a full bag.

Tees, mat thickness and ball condition

Mat thickness raises the ball. Some units expect the ball at the same level as the unit, so if the maker says so, place the unit on a platform or shim to match. The requirement varies from one device to the next, and some units do not care at all, so check your model.

Tee height is the other physical variable. Use consistent tee heights, because rubber tees in mats vary from one product to the next. If your driver tee height is drifting, the driver tee height and mat fixes guide covers how to set it up consistently.

Ball condition matters more than most players expect. Clean white balls read best on many camera units. Scuffed or dirty balls can misread, and the misread often shows up as inconsistent spin rather than an obvious error. Replace balls that have clearly worn, and keep a small cloth near the hitting spot.

Some units need specific balls or markings. The Uneekor QED uses marked balls. The Rapsodo MLM2Pro uses RPT balls for measured spin. The FlightScope Mevo+ uses a metallic sticker for indoor spin. Check each maker's ball guidance before you buy a supply of balls for your simulator, because a ball that works for one unit may not suit another.

One habit that some camera owners follow is turning the ball's logo toward the lens. Treat this as optional unless the maker says otherwise. It will not fix a placement problem, but it costs nothing to try if the readings are otherwise steady.

Reading the numbers for setup errors

The numbers on screen are a diagnostic. When something looks wrong, the pattern usually points to a specific cause. The table below pairs common symptoms with the setup issue most likely to produce them, along with the first thing to check.

What you see	Likely setup cause	Check first
Shots not registering or intermittent misses	Ball outside the read zone, extra balls or tees in view, poor lighting	Ball on the marked spot, and clear the zone
Every shot pushed or pulled by a similar amount	Unit, mat or software target misaligned	Re-run alignment
Driver shows a downward attack angle and high spin	Ball too far back in the stance	Move your feet back so the ball is inside the lead heel
Irons often launch unusually high and thin	Ball too far forward in the stance	Move your feet forward
Spin readings jump around shot to shot	Dirty ball, missing sticker or marked ball, lighting glare	Ball condition and lighting
Readings change after a session break	Unit or mat moved	Tape marks

Work through the most likely cause first, and change one thing at a time. If you move the ball, the stance and the unit height all at once, you will not know which change fixed the problem or which one introduced a new one.

For calibration and software causes, the calibration and software fixes guide covers settings that sit outside the physical setup. Dirty lenses and sensors belong in the sensor cleaning and calibration guide, and lighting problems are covered in the lighting that causes misreads guide. If you see irregular reads across a whole session, the why readings go wrong page explains the common causes in more depth.

Fix misreads and calibration

Left-handed players and shared bays

Handedness changes the setup more than most owners expect, and the amount of change depends on the unit's mount. The four device classes respond differently, so check your unit before you assume one rule applies to everything.

Side-mounted camera units must move to the other side of the ball for a left-hander. Mark both unit positions on the floor with tape so the switch is quick and repeatable. Without floor marks, it is easy to set the unit slightly off its original spot, and that small change can alter the read.

Rear radar units sit behind the ball and usually serve both hands without moving. That is one of the practical advantages of the rear mount in a shared room. Overhead units usually switch handedness in software rather than physically, so check the handedness setting in your software before the first shot.

Room width matters too. In a room about 15 ft wide, both hands can hit from a centred spot. In a narrower room, you may need an offset hitting spot and an aim adjustment in the software. Check how your platform handles that adjustment, because the options differ.

For a deeper look at setups that suit both hands, see the left and right-handed simulators guide.

Keeping the read zone clean

The read zone is only as clean as the space around the ball. Anything that enters the sensor's view can confuse the reading, and many of those things look harmless to the golfer.

Keep one ball in view at a time, and keep the ball tray out of the camera's field.
Remove loose tees, alignment sticks and markers from the ball's path and the sensor's view between shots.
Avoid mirrors and metallic or glossy objects near camera units.
Sweep loose turf fibres and dust, and keep lenses clean according to the maker's cleaning instructions. The sensor cleaning guide walks through the steps.

Lighting plays a similar role. Glare from a bright lamp or a reflective surface can produce misreads even when the ball and the unit are both in the right place. Position lights so they do not shine straight into the camera, and check the maker's lighting guidance before you change the room.

Where the mat sits in the room

Room geometry sets the limits on where the mat can go, and some of those limits only appear after the unit is mounted. It is much easier to plan the mat position first.

Ball to screen is commonly 8 to 12 ft. That range is a starting point, and the ball to screen distance guide covers how the number changes with your screen and projector.

Rear radar units need room behind the golfer as well as ball-flight distance in front. Check the maker's room guide, because the exact figure varies by model.

Here is the arithmetic. Suppose a rear radar sits 6 to 8 ft behind the ball, as commonly quoted, and the screen sits 8 to 12 ft in front of the ball. By our math, the distance from the unit to the screen runs from about 14 ft (6 plus 8) to about 20 ft (8 plus 12), before you allow for the golfer's stance and backswing. Check that span against your room before you buy. If your room is shallower, consider a different layout or a different unit.

Overhead units fix the hitting spot to the mount, so plan the mat position before you install anything. Moving an overhead unit after it is in place is a bigger job than repositioning a side unit.

Side clearance matters for the swing itself, and for moving a side unit across when a left-hander uses the bay. Leave enough room on the side of the mat for a full swing, and for the unit's new position if you switch hands.

Room size and ceiling height both affect how the layout works. The room size and ceiling height pages go through those measurements in more detail.

Setup questions from new simulator owners

Most of the questions new owners ask come back to the two placements. The answers below are short, and each points to the part of this page that covers the detail.

Should I use a different ball position indoors than on the course?

Your ball position in your stance should match the course. What changes indoors is that the ball stays on the sensor's spot and your feet move around it. A flat mat removes uneven lies, so you will not need slope adjustments. Think of the mat as a fixed reference point: the ball goes where the unit needs it, and your stance adapts to that spot for each club.

Why does my launch monitor miss shots when the ball is teed up?

The teed ball may sit above or outside the camera's field of view or the expected read height, and tall tees and thick mats make that worse. Some makers suggest raising the unit or adjusting placement for the driver, so check their guidance on tee height and unit height. The right fix depends on the model, so confirm it in your manual. If the problem continues, the tee height and mat fixes guide is the next step.

Are alignment sticks enough, or do I need an alignment mat?

Two sticks, one on the target line and one along your toes, cover most needs and cost very little. Mats with printed lines or tape marks help you repeat the same setup, which saves re-checking alignment every session. Printed lines are a convenience rather than a requirement. If you want that repeatability, the hitting mat guide compares the options.

Can I use range balls or coloured balls with a camera unit?

Many camera units read best with clean white premium balls. Worn range balls and some coloured balls can misread spin, and some units need marked balls or stickers. Check the maker's ball guidance first, then start with clean balls on the marked spot.

How far behind the ball should a radar unit sit?

Follow your manual, since distances differ by model and room. Figures of roughly 6 to 8 ft are commonly quoted for rear radar units, and about 8 ft is cited for the Mevo+ indoors. The unit should sit on the target line and be level, so check the maker's room guide before you mount anything.
