What is Page Grid Ruler?

'Page Grid Ruler' is an essential Chrome extension that helps Web designers and developers in measuring page layouts. It brings a grid view and rule to your screen facilitating measuring page length, width, start, and endpoint in pixel units along with customizable grid size and thickness. However, it does not support measurements in 'mm', 'cm', or 'in' units and needs the screen's PPI value for conversion.
