Universal Desktop Ruler allows you to measure not only a straight line distance but any curved distance on the Screen. It allows you to quickly and accurately measure distances, areas and perimeters of figures on the screen. You can determine your own scale and get results in pixels and your units of measurement (feet, inches, meters). It is useful for measuring distance and area on a map, finding area and perimeter in a house project for example. Additionally, it has a screen magnifier function.
