The Screen Protractor is a tool that measures angles up to the nearest Degree or Radian on your screen. Its floating feature allows measurement of any angle on your screen without interrupting your work on other applications.

The software lets you download a feature-limited trial to evaluate it for as long as you need. If you purchase the full version, you can unlock measuring a full 360 degrees and access the advanced features. The Protractor's interface is easily navigable, allowing the user to control views with the keyboard.
The Units menu allows you to choose from a predefined list of units like degrees, radians, revolutions, grads, mils, minutes, seconds, and bearings. If need be, customers can also configure their units to create custom settings. The software's interface is skinnable, allowing users to download a new skin to change the appearance.
The software's primary features include easy angle measurements, precise keyboard controls, measurements in degrees, radians or five other units, transparent interface, and a 30-day money-back guarantee. With its accurate solutions and easy-to-use interface, the Screen Protractor can handle any angle measurement task with ease.
Version 4.0: New features including new semi-transparent skins and an updated calibration screen allowing more options for measurement. We've added a transparency slider and a link to our Magnifier tool.
