I am looking for alternative fonts to use on a web site that are similar to DINPro Bold, Light and Medium.
They don't have to be free fonts, but can be through a service such as TypeKit or Fonts.com.
Any advice would be greatly appreciated.
Google Fonts has PT Sans by ParaType https://www.google.com/fonts
Apparently it is widely used in Germany and for that reason they were allowed to remake their own version which is nearly identical. I can't remember where I heard that but here is the alternate version.
