Ever wanted to know how many pixels wide something is on a web page. I used to find myself doing a print screen, pasting into my favorite editor and then measuring it using that application’s measuring device. I wanted to know how I could speed this up, because in my line of work it is necessary to know the measurement of elements on a web page. How could I accomplish this easily? I found a plug in that enables you to do this on the fly using Mozilla Firefox. This plug in is great, you just install it, then a small tool appears int he bottom left hand corner of your browser!

Example of the Firefox add on called MeasureIt
Just click on the tiny ruler icon and a cross-hairs will appear. Drag the cross-hairs over the desires area of measurement, and a measurement will appear.

Firefox MeasureIT add on in action!
After you are finished the measurement, just click the ESC key. Yes, it is that easy!
