Just found a great Firefox plugin which is the perfect tool to make measurements in pixels; MeasureIt! You get a rule which you can be used to find out the width, height or alignment of any element on a page. MeasureIt can be access with a single click and doesn’t need any configuration!

MeasureIt in action
It works really simple:
- click the MeasureIt button in the status bar to activate /de-activate it
- Now click and drag out a ruler box
- click and hold to move the ruler box
- Arrow Keys to adjust size of ruler box by 1px
- Arrow Keys + SHIFT to adjust size of ruler box by 5px
- click and drag bottom right corner of ruler box to resize
- CTRL + Arrow Keys to nudge ruler by 1px
- CTRL + SHIFT + Arrow Keys to nudge ruler by 5px
- click the “X” to close that ruler or click outside of it to begin drawing another ruler
- ESC key to turn off MeasureIt

interesting.. a digital measuring tape..
It’s really a cool plugin and great in case you want to design or know the measurements of something in your browser!
