Yes, you can measure inside a Matterport tour from a phone. According to Matterport's help centre, updated July 17, 2026, Measurement Mode works on any device, phones and tablets included, and any visitor can use it without a Matterport account. The one condition: the tour's owner must have left the mode switched on, which is the default.
Where to find the tool
Open the tour in your phone's browser. In the bottom bar, on the left, tap the ruler icon. An "Add Measurement" button then appears in the middle of the screen, and three icons show up at the top right: settings, help and close.
If there is no ruler, the owner has turned Measurement Mode off for that tour.
Taking a measurement, step by step
- Move through the tour to the spot you want to measure, facing it squarely if you can.
- Tap the ruler, then "Add Measurement." The cursor becomes a target with a scope that magnifies the area you are aiming at.
- Place the first point on a corner or an edge. By default, the point snaps to the nearest corner or edge.
- Drag the line along the edge you are measuring, horizontally or vertically, then place the second point. The distance appears on the line.
- Keep going if you need to: lines chain together so you can work your way around an object such as a table. Confirm to finish.
- To delete a measurement, tap the trash can.
Matterport's help article describes these steps on a desktop, with clicks. On a touch screen the buttons are the same and your finger does the mouse's job. A desktop adds two shortcuts: double-clicking the floor or the ceiling draws the room height in one go, and the Escape key ends the current measurement.
Measuring a room on the floor plan
For a room's length and width, the floor plan view is easier than measuring from inside the room. Switch to the floor plan view in the bottom bar, open Measurement Mode, then draw your line from one wall to the other. Zoom in on the plan to place your points more carefully.
Settings worth knowing
The settings icon at the top right gives you three options:
- Snapping: on by default, it pulls your point to the nearest corner or edge. Turn it off to place a point freely.
- Continuous lines: on by default, they chain one measurement into the next.
- Units: feet and inches, or metres and centimetres. The unit is picked automatically, but you can change it.
What a visitor cannot do
A visitor's measurements are not saved; they are gone once you leave the tour. Matterport suggests taking a screenshot if you want to keep them.
The tour's owner, on the other hand, can take measurements in Edit mode, name them, hide them and decide whether visitors see them. The owner can also turn Measurement Mode off for a given tour.
How accurate is it?
The tool gives a good estimate, not a surveyor's figure. The help window inside Measurement Mode says as much: accuracy is not guaranteed and depends on the camera used and the capture conditions. Here is what Matterport publishes on the subject:
- Rooms: in a Matterport test on a house, room dimensions captured with the Pro2 camera were typically within 1% of a laser distance meter reading. On a 5 m room, that is about 5 cm.
- The Pro3 camera: its stated accuracy is ±20 mm at 10 m for a single scan in controlled conditions. For measurements taken inside the tour, Matterport says the Pro3 and Pro2 are comparable.
- Long distances: the more scan positions a distance spans, the more small errors can add up.
- Small objects: the tool works on a lightweight 3D mesh. A thin, small or shiny object, such as a baluster, a pipe or a light fixture, measures poorly.
Two habits help. Look at your measurement from more than one angle to confirm the points sit where you think they do. And, as Matterport recommends, double-check any critical dimension on site before ordering custom furniture or materials.
