I wanted to buy a special microfiber cloth from the Internet. It measures 40 x 35cm and I don’t have any idea how big is 40 x 35cm. I know it’s small, but how small is it? I can’t be really sure until I’ve got the measurement from a ruler or measuring tape. I tried looking for a measuring tape or even a ruler but I couldn’t find one. In fact, I can’t even remember when was the last time I used a ruler or measuring tape to measure something!
Desperate to know, I thought I might find something on the Internet that can teach me how to measure without using a ruler or measuring tape. Wonderful, I found a solution and now I don’t even need a ruler or measuring tape anymore to measure length, width and height!

JS Screen Ruler is a great tool that allows you to accurately measure anything on your screen. This is especially useful when measuring graphics, web page browser sizes or whatever. Screen Ruler can display Pixels, Inches, Picas or Centimeters.
Right clicking on the ruler gives you the ability to flip the ruler from horizontal to vertical, mark the exact center of the ruler with a vertical slash, move the ruler to the far left of your desktop screen and also setting the different measuring system to either pixels, inches, picas or centimeters(cm).
JS Screen Ruler is FREE but it also has a shareware version which offers more features such as rotate the ruler, set transparent background, capture active window size and customize color. I personally think that using the FREE version is good enough. Actually I found quite a lot of free on screen ruler but they all have nearly the same features.
what application do i use to open a .ini file?
Yes, you can. You just have to configure the correct pixel density. You have to only know your screen size and resolution, then look it up in Wikipedia:
en.wikipedia.org/wiki/List_of_Device_PPI
Too bad that you can’t be sure if your monitor is in the right configuration to give an accurate measure. Instead, it can be useful if you want an approximate measure =]
that awesome.thank dude
Thanks for letting me know about the typo. There’s no auto spell check for titles and I guess I have to be more careful in future :)
There is no “y” in his name Varun…if you are going to try and act sarcastically funny (no matter how pathetic), do it correctly!
Go die man.
Mr Reddy,
Thanks for that insightful and such a relevant observation! You areally are the kind of audience that Raymond targets!
Get a life man.
you’ve written “heigth” instead of “height”
MR-Ruler is nice. Thanks for sharing.
Try MB-Ruler as well, the freeware version is as good and has even more features around including a loupe tool and color picker too.
