Image Ruler - Measures

The most elegant way to measure anything in your photos. Free to try, no fuss.

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.
