A Ruler for Windows is an on-screen pixel ruler for your PC. It provides your choice between a rich wood grain ruler, or at the touch of a button, a clear see-through plastic ruler. As you can see through the clear plastic ruler you can even continue your typing under it. Special 2x, 3x, and 4x modes allow you to take a snapshot of your primary screen and magnify it so you can more easily measure between very fine points. The ruler can be flipped horizontally or vertically, resized to an exact length or resized by dragging it to a desired length. You can click near a tick to have a measuring line automatically drawn at an exact location. The question mark button allows you to learn more about other features and functions. Version 1.0.5 now runs over multiple screens.
