Instructions for the Photo Measure Tool

What this Website Does

Under some conditions it is possible to determine the scale of digital photographs. This site displays some of those photos and allows measurements to be made on the objects in the photo.

Zooming and Making Measurements

To enlarge a portion of a photo, click and drag over the region you wish to see. You can only enlarge the photo to 200%. You can zoom-out by using the minus-magnifing glass icon and you can view the full photo with the "All" icon.

A measurement is started with a single mouse click. The end point is set with a second single mouse click.
