BitRule

BitRule is a Windows screen measurement tool whose purpose is to help you calculate the distance between two points on your desktop.

Simple looks

Although the utility embeds only a few configuration settings in the main window, which are not difficult to decode, it still provides a help manual in case you have any questions regarding its capabilities.
A preview panel is integrated in the GUI for helping you view the exact location of your mouse. Plus, you may zoom in or out of the displayed image.

How it works

The application implements a simply system for helping you find out the distance between two points. It automatically displays in the program’s titlebar when you need to click on the desktop for recording the first and second measurement points.
BitRule reveals information about the horizontal and vertical distances between two points, length (diagonal or straight line), as well as angle between the diagonal and true horizontal lines.
The utility is able to perform the calculations in inches, centimeters, picas or pixels. The calculation results are automatically copied to the clipboard and saved to a plain text file format. What’s more, you can manually copy the desired information to the clipboard (e.g. length, angle).

Calibration tweaks

BitRule advises you to make a quick calibration before performing any measurements as the results may be incorrect. It comes with support for a built-in calibration mode that allows you to adjust the resolution.

Bottom line

All things considered, BitRule integrates a basic suite of features for helping you perform desktop-related measurements. However, it hasn’t been updated for a while and it shows. We have tested it on Windows 8.1 Pro and experienced several freezes.
