Notepad++ 32 Bit – Horizontal Ruler Plugin

What:  Notepad++ 32 Bit – Horizontal Ruler Plugin


Where: Download here: NppHorizontalRuler.dll DOWNLOAD

Why:  Useful plugin to add a ruler to the top of the Notepad++ Interface.

When: Verified the plugin works on Notepad++ 32 bit (only), version 7.6.4 – March 6, 2019.


  1. Download the NppHorizontalRuler.dll file from the link above
  2. Create the folder C:\Program Files (x86)\Notepad++\plugins\NppHorizontalRuler\7.6.4_2
  3. Close Notepad++.  Drop the file into the folder.  Open Notepad++.
  4. To enable the ruler: Go to Plugins menu > Horizontal Ruler > RulerToggle7.6.4_1


Who:  I needed a horizontal ruler and eventually found a site where someone had created a ruler but it was written in japenese.  Functional but I couldn’t read it the site or the settings.

After posting the link here with instructions on how to download and install it, Jeffery Grossman took the time to update and translate the code for it. I now link to his repo for download. 

Thank you to those two people.
