MB-Ruler add three instruments for measuring to your browser:
– a triangular ruler to measure distance and angles
– a horizontal and vertical ruler with help lines
– a screen grid that divides the web site in equal rectangles
All three instruments can be shown and hidden by a simple click.
Its very good and works perfectly for my school work
Downloaded and installed on Chrome. Nothing happens, not clear how to use this app. It might be a good tool, but who knows how to use it? Removed
I installed this 5 year old extension and without reading any instructions was able to use it as i needed within seconds. really great. thanks.
Underrated highly useful online measurement tool for mathematicians, engineers and physicists.
On long pages it is impossible to use the fixed elements at the top – please fix it.
Great for finding roof slope
This works well. However, it would be nice to be able to start it from the extension instead of on the side of the web page.
Useful extension for the angle finding (protractor) and for the ruler. The grid leaves a little to be desired. I like the dragability of the grid size, but would like to be able to set the size with numbers and to be able to change the grid unit…most importantly would be to set the grid to be positioned at 0 0!
Great extension for the other tools, though. …of course, all the browser developer tools have rulers now…
好用。试了Page Ruler，启用后页面格式直接乱了。又试了Grid Ruler，简洁好看，但是只能用来对齐，无法直接看到元素的position信息。最后试了这个，除了激活生效需要reload页面，停止使用，需要在扩展程序里点停止。基本没毛病。强烈推荐。
Please allow for hiding and accessing the toolbar, it affects other browser buttons. Otherwise, cool tool! I have to go into the extensions, un-check your tool until I use it and then have to go back and recheck. It would be very helpful to remove toolbar from constant access to a hide and show access setup. Thanks.
Muy buena herramienta para utilizar como referencia de medidas.
Does Not work on MAC.
It simply do NOT work.
Best ruler extension
COOL APP
You really need to fix this so it can work on images from facebook!
Much needed tool but needs fixing.
Everything works, thanx. The only one that worked for me.
Works great compare to many others. I am missing the ability to activate it from toolbar
great tool for web-developer
but
can’t scale distances below 10px
sad
Absolutely love the automatic sizing information and how easy it is to line a bunch of things up.
