ScreenRuler is an online tool that allows users to measure the size of objects on their screen. It is a helpful tool for web designers, digital artists, and any other user who needs to measure the size of images or other objects on their screen in order to create accurate designs or layouts. The app works by allowing users to draw a ruler directly on their screen, which can then be adjusted and moved to accurately measure the size of objects. ScreenRuler also has a variety of features and options that allow users to customize their ruler, such as color, opacity, and units of measurement. Additionally, ScreenRuler can be used to measure the distance between two points on the screen, and users can save their rulers for later use.
