Screen Ruler is a lightweight and configurable ruler tool for Windows Desktop. It allows you to measure the size of elements on the screen in different units, including pixels, centimeters and inches. Measuring is possible either using a two-dimensional, rectangular ruler scale or a one-dimensional, horizontal or vertical scale. The ruler can be moved and resized precisely using either the mouse or the keyboard and custom marking lines can be added. Besides coming with a light and a dark theme, Screen Ruler also allows you to fully customize its appearance by changing all color settings.
