Image Ruler - Measures
iOS Universel / Productivité
Measure anything in any photo.
Take a photo or import one from your library, place a reference object you already know the size of, and instantly calculate real-world measurements — lengths, angles, and areas — directly on the image.
How it works
Set a reference line on a known object in your photo. From there, every measurement you draw is automatically calculated in real scale.
What you can measure
Ruler — measure distances and lengths
Arrow — annotate with directional measurements
Angle — measure the angle between any two lines
Area — tap points to outline a surface and calculate its area
Built for precision
Works entirely offline — no internet required
Metric and imperial units
Pinch to zoom for precise point placement
Undo and redo any change
Hide or show your reference line at any time
Tips for accurate results
For best accuracy, make sure your reference object and the object you're measuring are in the same plane, and that the camera was parallel to both when the photo was taken. Perspective distortion affects results.
Measurements are estimates based on the reference you provide.

Refreshed UI
A cleaner, more intuitive interface designed to get out of your way and let you focus on measuring. Everything is faster and easier to reach.
New: Angles & Areas
Go beyond straight lines. Measure the angle between any two surfaces, or outline a surface to calculate its area — all in real scale.
New: Export & Share
Share your measurements as an image with all annotations overlaid, or copy individual values directly to your clipboard. Perfect for sending to clients, collaborators, or keeping for your records.
New: Flip & Rotate
Imported a photo in the wrong orientation? Fix it instantly before you start measuring.
