There is an error in the numeric scale in the map composer. For example, if we print with a scale of 1:20 000, the distances on the map are in reality around 1:15 000.

Thanks for your time.

  • Target version set to Version 2.2
  • Status changed from Open to Feedback
  • Priority changed from High to Normal
  • OS version deleted (2.0.1)

There is no crash or data corruption, so I'm lowering the priority.

Can you please test the latest master and report back? Thanks!

I can reproduce this behaviour. The output seems to have only 2/3 of the scale which is entered in the print composer.
Attached is a pdf of the boundary of Vienna which should be 1:100.000 on a 420x420mm Paper. In reality it is about 1:66.666. I had the same issue with other objects in other locations with 1:50.000, also with different paper sizes.

System: Linux Mint 16
Qgis version: nightly & 2.1

Seems also to me that something is wrong...

Sorry - I'm on holidays for a couple of weeks and can't investigate this for 2.2. I'm happy to take a look after that if no one tackles it in the meantime.

I did some more tests. The reason might just be a mix-up of reference systems, since another example concerned with the boundary of upper austria works fine.
