Everyone remembers our school supply kit from grade school. It was a zippered bag and it had our pens and pencils, those pink rubber erasers, that awful stabby thing, and lastly, a protractor. The protractor was probably the most useful thing - you could measure straight lines as well as angles, and it was responsible for a lot of smiley face stickers on your homework.

But today, we no longer work with pencils and college-ruled paper. Today, most of what we work with is computer-based - even if a diagram starts on paper, it most likely gets digitized and stored as an image eventually. This is true for many disciplines including engineering, cartography, architecture, criminology, math, and physics.

Screen Protractor updates your old grade-school protractor for the digital age. With Screen Protractor, you can measure any angle on your computer screen to the nearest degree or radian quickly and easily.

Screen Protractor appears as a transparent tool that sits as an overlay on top of whatever design, map, photo, or other image you have displayed. The best part about Screen Protractor are the skins that are available for the application - you can download new skins and change the user interface to suit your own needs. You can even design your own skins!

With Screen Protractor, you have the ability to adjust the transparency of the overlay, as well as measure in any of eight different units. Keyboard controls assist you in measuring your screen to the highest degrees of accuracy and precision!
