AR Measure
About AR measurement
How does AR measure distance?
AR combines camera images with motion sensor data to estimate your phone’s position and the space around it. Once you place two points, it can calculate the distance between them in 3D space.
How is area calculated?
Connect points on the same plane to form a closed shape, and the tool calculates its area from the boundary. You can measure irregular polygons as well as triangles and rectangles.
What is the difference between ground and side modes?
Ground mode is for horizontal surfaces such as tabletops and floors. Side mode is for vertical surfaces such as walls and cabinet doors. Choosing the mode that matches the surface keeps subsequent points on the same measurement plane.
Frequently asked questions
How accurate are the measurements?
Results depend on your device, lighting, surface texture, and where you place the points. They are suitable for everyday estimates. Use a physical measuring tool to confirm precise dimensions.
How can I get more stable measurements?
In a well-lit area, slowly move your phone to scan your surroundings before placing points. Avoid glass, mirrors, and surfaces with little visual detail, and stay reasonably close to the object.
Does automatic selection follow the object’s actual boundary?
Automatic selection estimates a rectangular region from the camera image. Backgrounds, shadows, and viewing angles can affect the result. Before applying it, check that the purple outline matches the area you want to measure. You can also place points manually.
Why can’t I start measuring?
This tool requires a device and browser that support WebXR AR. Actual availability varies by device.
