Brilliant! I love it! I test websites for a living and when the spec says something has to be 18pixels from the edge of the screen, I used to have to screen shot it and switch to photoshop to count. I can't believe I've never seen this before. Well done! It's so easy to use!

Excellent aad-on, suggested improvement Rated 4 out of 5 stars

Excellent add-on. Definitely a must.
However, I often find it hard to make a highly precise selection. The add-on could therefore support guide lines and have the MeasureIt ruler snap to them, like in image editing software.
Has this feature been considered?

Nice tool. Save you a step without opening an image editor to get the size of a copy web image.

A nifty tool Rated 5 out of 5 stars

I have found this tool to be very useful. I used to have to take a screen shot then copy it into Photoshop or Fireworks to measure an area. Now it's easy.

This is one of my most used add-ons. I just wish it also provided X and Y as well. None the less, it is a great app.

Excellent Add-on. Quite simple and pretty useful.

Kevin, what about to display Aspect Ratio? For example, it would be nice to know if a screenshot is 16:9 or not.

Good Add-on Rated 4 out of 5 stars

I really like this add-on...one thing I find very annoying is that if you drag your cursor too fast the drag event is intercepted by the info box.

MeasureIt Review Rated 5 out of 5 stars

Definitely an Add-On that comes in handy when needed. Let us know when you're able to tackle additional features on your wish list (mentioned on your home page), such as on-the-fly resizing and the grid.

Such a simple idea, but it makes life so much easier when you're developing and trying to fit pieces together.
