Screen Calipers

Screen Calipers is a small tool that allows you to easily measure distances on your monitor.

This can be useful for web designers, graphic designers, etc. The application is simple to use, just drag the mouse over the object to be measured as if you were measuring with a classic sliding scale.
You can change the colors, swap and move the application keyboard, or you can change the whole skin. The result is the absolute distance in pixels.

This version can be used for free, with optional registration, 360 degree rotation, additional units (inches, cm, etc.) including custom units and relative measurement techniques are added.
