Today, I’ll show you very useful web designing tool called MeasureIt, It measuring the accurate width and height of any element on any web page. I like to use it to measure some logos and similar stuff.
1) Downlaod MeasureIt 0.4.6 from this link and install
3) Click the MeasureIt sign at the left bottom of Mozilla Firefox window
4) Drag the ruler to select the element for example hackspc.com logo and it will automatically show you the exact width and height in pixels of the selected image.
