Image Distance Measurement Tool
Click two points on an image to calculate straight-line distance, horizontal and vertical change, angle, and optional scaled units.
Upload an image and click two points to measure pixel distance, axis differences, and angle.
Two-point pixel measurement
Measure straight-line distance using coordinates mapped to the original image.
Axis and angle results
See horizontal delta, vertical delta, and signed angle alongside total distance.
Optional scale conversion
Enter units per pixel and a short unit label to convert pixel measurements.

Measuring accurately from an image
Pixel distance is exact for the raster file, but real-world distance requires a known scale. If one pixel represents 0.5 millimeters, enter 0.5 as units per pixel and use mm as the unit label. Perspective, lens distortion, and unknown resizing can make real-world conversion inaccurate.
Често постављана питања
How is pixel distance calculated?
The tool uses the Pythagorean distance between the two original-pixel coordinates.
Can it measure real-world units?
Yes, if you know the correct units-per-pixel scale for the image.
