Universal Desktop Ruler

Universal Desktop Ruler is a simple program that sits in the systray and helps you measure a straight line distance, area, perimeter, and angles of figures on the screen.

Once the installation is complete, the app is sent directly to the system tray, where you can access all its functions. It also features a measuring scale and history to view all the calculated values easily.

The selection process is quite easy, you use the left mouse button to choose the desired monitor region, and set it with the right button. The area is scanned, and the total values are displayed in a small window. There you can name the calculation and proceed to the next measurement.

What's more, the tool lets you determine the angles of different geometrical shapes by using the same left button to mark the vertex of the angle and the two rays. The value is shown in a separate panel. Another handy function is the counter, which counts all the objects that are on your screen or from a house design.

Each calculation can be copied to the clipboard and used in your house projects or homework. Plus, the app takes a snapshot of each measurement that can later be attached to your work. Last but not least, from the preferences, you have the option to set your own hotkeys for each feature, using any key combination. Unfortunately, there is no clear function that lets you change the measurement units to the local one.

Taking everything int account, Universal Desktop Ruler is a reliable application designed to help you measure any region of the screen, as well as calculate area, perimeter, angles, and count all the objects.
