What is AR Measurement Tool?
The AR Measurement Tool is a free augmented reality application that lets you measure real-world objects using just your smartphone camera. Using advanced AR technology (ARCore for Android and ARKit for iOS), you can accurately measure distances, heights, and dimensions without any physical measuring tape or ruler.
How Does AR Measurement Work?
AR measurement technology uses your phone's camera, gyroscope, and accelerometer sensors to detect surfaces and calculate distances in 3D space. The tool:
- Scans the environment: Your camera identifies flat surfaces and creates a virtual grid
- Places points in 3D space: Tap to mark start and end points for measurement
- Calculates distance: The AR system measures real-world distance between points
- Displays results: Get measurements in centimeters, inches, or meters

Accuracy & Limitations
The AR Measurement Tool provides measurements with approximately ±2-5cm accuracy, which is suitable for most everyday measurements. However, it's not recommended for professional construction or engineering where millimeter precision is required. For best accuracy:
- Measure objects within 0.5m to 5m range
- Avoid very large or very small measurements
- Use proper lighting conditions
- Keep your device stable
Privacy & Security
Your privacy is important. This tool:
- 🔒 All measurements are processed locally on your device
- 🔒 No images or videos are uploaded to any server
- 🔒 Camera access is only used for AR measurement
- 🔒 No personal data is collected or stored
Troubleshooting
"AR Not Supported" Message?
Your device may not support AR technology. Check if your phone is ARCore (Android) or ARKit (iOS) compatible. Try updating your browser to the latest version.
Camera Not Working?
Make sure you've granted camera permissions. Check your browser settings and ensure no other app is using the camera.
Inaccurate Measurements?
Improve accuracy by measuring in better lighting, moving your phone slowly, and ensuring the surface is flat and textured.
