The boundary (once called Guardian) keeps you from walking into walls and furniture while you play. Here is how to set it up, how to switch between Stationary and Roomscale, and what to do when the headset keeps forgetting it.
What the boundary does
The boundary is the virtual fence that marks your safe play area on a Meta Quest. When you get close to its edge, the headset shows a grid or switches to a view of your real room so you can see what is around you. Older guides call it Guardian, and some games still use that name, but Meta's menus now simply say Boundary.
It relies on the headset's inside-out tracking, so the cameras need to see your room clearly. Most boundary problems are really tracking problems, which is why lighting and room changes come up so often below. Meta's boundary setup article is the official reference for everything in this guide.
Stationary or Roomscale: which should you use?
Stationary is for playing while sitting or standing in one spot. The headset creates a small default area centred on you, which Meta gives as 1 m by 1 m (about 3 by 3 feet). It suits seated games, films and apps where you do not walk around.
Roomscale is for games where you move. You draw the edge of your play space on the floor with a controller. Meta recommends at least 2 m by 2 m (about 6.5 by 6.5 feet) of safe, clear space. If your room is smaller than that, Meta suggests using Stationary instead, and choosing games marked for seated or standing play. Our VR comfort tips explain why smooth, small-space games can be easier to settle into.
How to set up or change your boundary
Press the Meta button on your right controller to open the Navigator. Select Quick controls, then Settings, then Environment setup, and choose Boundary. From there, select Adjust boundary to draw a new Roomscale area or adjust a Stationary one. You can also clear your previous boundary and create a new one from the same screen.
When you draw a Roomscale boundary, stand near the middle of the space and trace the edge on the floor with the controller, leaving a margin away from walls, furniture, doorways and anything you could hit with your hands. Check the floor level is right when prompted: if the virtual floor sits too high or too low, games feel off and you may reach for the ground and hit it.
If you are already inside a game that wants more space, you do not have to quit. Open Quick controls, select Boundary, then Switch to Roomscale. Meta notes that VR Home starts with a Stationary boundary by default, and the first time you open an immersive app it asks you to pick Stationary or Roomscale. Your preference is saved separately for VR Home and for apps.
Useful boundary settings most people miss
The Boundary settings page has a few extras worth knowing. You can reset the floor level, change the Roomscale boundary colour so it stands out against your game, adjust Roomscale boundary sensitivity, and turn on a glanceable boundary that shows your position when you look down. Meta also explains that turning passthrough on or off does not change your boundary.
If you share the headset, remember that a boundary drawn for one room does not help someone playing in another. Set it up again whenever the headset moves rooms. For children, the supervision tools in the Meta Horizon app are a separate layer of control, covered in our VR for kids and families guide.
Why the headset keeps forgetting your boundary
Meta's boundary troubleshooting article gives two main reasons a headset forgets a saved boundary. The first is that the room has changed: furniture moved, things hung on the walls, or lots of people walking around the play area. The second is that the lighting has changed, such as daylight from a big window versus lamps at night, or light coming from a different direction.
To help the headset recognise the room next time, Meta suggests standing as close to the centre of your play area as you can while you draw, and looking around the whole room rather than in one direction. Use steady, even light: Meta's rule of thumb is that if you can comfortably read a book in the space, the lighting is enough. Avoid direct sunlight, which is also a risk to the lenses themselves.
Boundary not working or tracking lost
If the boundary will not appear, will not let you draw, or you see a tracking lost message, the headset has probably dropped from full six-direction tracking (6DoF) to rotation-only tracking (3DoF). Meta's headset tracking article explains the difference: in 6DoF you can walk towards or away from objects, while in 3DoF you can only look around. Boundaries need 6DoF.
Work through these steps in order. First, improve the lighting: turn on more lights or move to a brighter room. Second, wipe the tracking cameras on the front and edges of the headset with a dry microfibre cloth, and remove anything reflective or very bright, such as mirrors or LED strips, from the cameras' view; Meta's tracking troubleshooting article lists these as common causes. Third, check tracking is switched on: open Quick controls, select Settings, then Movement tracking, and make sure Headset tracking is on. Fourth, restart the headset.
If it still misbehaves, clear the boundary history from the Boundary settings and draw it again. Be aware that on a headset with several profiles this clears the history for all of them. If nothing works and the headset also shows other faults, our factory reset guide covers the last-resort option.
Can you turn the boundary off?
Meta's boundary article does not offer a setting to switch the boundary off for normal play, and we would not go looking for a workaround. The boundary is a safety feature: it is the thing stopping a swing in a fast game from hitting a TV, a wall or a person. If the boundary keeps getting in the way, the better fix is usually to clear more space, use Stationary mode for seated apps, or adjust the sensitivity. Mixed reality apps work a little differently because you can see your room, which our mixed reality explainer covers.
Frequently asked questions
How do I set up a new boundary on Meta Quest 3?
Open the Navigator with the Meta button, select Quick controls, then Settings, Environment setup and Boundary. Choose Adjust boundary to draw a new Roomscale area or adjust a Stationary one.
How much space do I need for Roomscale?
Meta recommends at least 2 m by 2 m (about 6.5 by 6.5 feet) of clear space. In a smaller room, use Stationary mode.
Why does my Quest keep forgetting my boundary?
Usually because the room or the lighting changed since you drew it. Draw it from the centre of the room, look all around while drawing, and use steady light without direct sunlight.
Why is my Meta Quest boundary not working?
The headset has probably lost full tracking. Add more light, wipe the front cameras, check that Headset tracking is on under Movement tracking, restart, and clear the boundary history if needed.
Is the Guardian the same as the boundary?
Yes. Guardian is the older name for the Quest boundary system. Current Meta menus call it Boundary.
