HTML5 Ruler

HTML5  Ruler can be used to measure content displayed on a Web page or to measure real-life objects by placing them over the screen.

The ruler works in the EU and US metric system (centimeters and inches) and can be easily be calibrated to reflect a real metric scale (if displayed on mobile, desktop or TV devices where the zoom level may disrupt the measuring scale).

If holding CTRL, the ruler can also be rotated to measure non-square objects.
