Is there a free plug-in for Adobe Reader to measure a distance on a PDF?

Is there another free reader out there that has this?

I am using the free PDF-XChange pdf viewer, and it comes with a measuring tool. Screenshot taken from the free version:

Adobe reader itself has a measure feature under "tools/measure":

The measuring tools are especially useful when you need to know the distances or areas associated with objects in a form or computer-aided design (CAD) drawing... The measuring tools are available to Reader users only if the PDF creator enables measuring functionality.


As of this writing, the Linux version of Acrobat Reader is missing the tool. Foxit is another alternative which includes a measure tool.

"The measuring tools are available to Reader users only if the PDF creator enables measuring functionality." -> Does it means we need Adobe Acrobat Pro to create the PDF? –  YudhiWidyatama Feb 2 '14 at 13:31

Foxit Reader :

check it out here http://www.foxitsoftware.com/pdf/reader/addons.htm it's free, so fast small (no more than 4Mo) and it has a lot of addons including Measure Tools tools.

Includes a distance tool, a perimeter tool, and an area tool that will help you to measure distance, perimeter or area on a PDF page and automatically transform the results into real-world values.

Looks like the measure tools are part of the Pro Pack. It's free for a year. –  Robert Jul 31 '09 at 15:23
a year is enough I guess :p –  user3864 Jul 31 '09 at 15:37
