About this app

Turn your phone into an AR ruler and tape measure. Point the camera, tap, and see measurements live on screen. No account and no sign-up.

MEASURE IN AR
• Distance between two points
• Height of a door, shelf or wall
• Multi-point measurements with area and perimeter
• Wall area for paint and wallpaper jobs
• Box volume from three measurements

LEVEL AND SLOPE
Check angle, level and slope using your phone's sensors. This tool works on any phone, with or without AR.

WILL IT FIT?
Enter the size of a TV, sofa, suitcase or any box, then place a virtual box in your room to see if it fits before you buy or move it.

MEASURE A ROOM
Tap the corners of a floor to get its area and perimeter. Close the shape to see a 2D floor plan with the length of each wall. Add doors and windows, then save everything in a project.

ESTIMATE MATERIALS
Get an estimate of paint, tiles or wallpaper from the rooms you measured. Use it to plan how much to buy, and keep some extra for waste.

SAVE AND SHARE
• Save a photo with the measurement drawn on it
• Keep a history of your measurements, with names you choose
• Group rooms and measurements in projects
• Export a list of measurements, or a whole project, as PDF or CSV
• Export a floor plan as an image or PDF
• Share a measurement card with a link to the app

MADE FOR EVERYDAY JOBS
Check if a sofa fits through the door. Measure a window for curtains. Plan furniture in a new room. Size up a shelf, a frame or a box before you buy or ship.

QUICK ACCESS
Add a widget to your home screen and use launcher shortcuts to open the tool you need in one tap.

UNITS YOU USE
Millimeters, centimeters, meters, inches, feet and inches, and fractions down to 1/16 inch. Switch units while you measure.

NO AR? NO PROBLEM
Phone without AR support? You can still measure.
• Photo measure: take a photo with a bank card or an A4 sheet next to the object as a reference, then measure on the photo.
• On-screen ruler: measure small objects in cm or inches. Calibrate it using a bank card to match your screen.

HELPS YOU GET A GOOD READING
A short guide shows how to get better results. AR Ruler tells you when tracking is good, when the light is low and when a surface is too plain. Move slowly and aim at textured surfaces for the best results. On supported phones, Depth Mode uses additional depth data from the camera.

IMPORTANT
AR Ruler gives estimated measurements. Results change with lighting, surface, distance, reference object, your phone model and how you move it. Material amounts are estimates too. For work that needs exact sizes, check with a physical tape measure. AR needs a phone that supports Google Play Services for AR (ARCore). Other phones can still use the level tool, photo measure and the on-screen ruler.

FREE, WITH ADS
AR Ruler is free to use. It shows ads. Some features, including PDF and CSV export, the detailed materials PDF, Depth Mode, floor plan export and creating additional projects, can be unlocked for individual uses by watching a rewarded video ad.

PRIVACY
Camera images are processed on your device and are not uploaded. Your measurements, photos and projects stay on your phone. The app asks for camera permission only to measure. Privacy policy: https://sites.google.com/view/privacy-policy-for-ar-ruler
