The Screen Protractor allows you to easily and quickly measure any angle on the screen to the nearest Degree or Radian.

To use the Protractor drag the application over the portion of a window you want to measure with the mouse. The center of the Protractor 'bullseye' is see-through so you will be able to exactly align it. To change the angle use the mouse to drag the two sliders. The number in the text box will show the exact angle in degrees.

The Protractor has several buttons which may appear differently on different skins. The arrow buttons will allow you to move and rotate the Protractor to measure any angle.

All the controls can be accessed through the keyboard:

When Closed the Protractor sits in the System Tray in the bottom right of the screen, you should see the Protractor icon next to your clock.

By Right-clicking anywhere on the face of the Protractor, or clicking on the System Tray icon the Protractor menu is displayed:



The menu is divided into three sections:

The Units menu allows you to choose a new unit from the list of predefined units.

You may also configure your own Custom Units using the 'Calibrate Units' menu option. Choosing this option will bring up a screen which allows you to choose a Custom Unit, rename and set the scale. You may also set the zero angle, enabling easy relative angles to be calculated.

The Skins menu presents several different choices for the user interface of the Protractor. By choosing the "Get More Skins" menu item you will be taken to the Screen Protractor skin webpage. This allows you to browse and download new skins. Full instructions are given on the webpage.

The Protractor can be configured to measure in the following units:

• Degrees
• Radians
• Revolutions
• Grads
• Mils
• Minutes
• Seconds
• Bearing

By clicking the 'Calibrate Units' menu item you can easily define any number of additional units of measurement.



The Protractor use conversion factors to determine the built in units. You can adapt these units and enter your own custom units.

In version 4.0 for Windows the configuration screen allows you the choice of setting the display to be in fractions, padding the display with blank digits and showing negative angles when measuring angles greater than 180 degrees. Double-clicking in the Unit Format column will show the popup that lets you control these settings.
