I'm working in an area in Baden-Württemberg, Germany. I loaded some OSM data in QGIS but the map display is distorted.

I tried ftools define projection with many different projections but nothing changed.

I tried: - WGS 84/ World Mercator - DHDN / Gauss-Kruger zone 2 - Google mercator - ETRS89 / UTM zone 32N - DHDN / Gauss-Krugerzone 3 - DHDN / Soldner Berlin

and many others...but nothing worked. There was no difference visible.

The basic thing you are stumbling upon is the difference between layer CRS and project CRS.

The OpenStreetMap data is in lat/long degrees, so that layer should have the CRS EPSG:4326. You can set it with right-click on the layer -> Set CRS for layer.

The project CRS can be different, and should be in your case. You can change tthat with Settings -> Project Settings.

EPSG:3857 should be the projection you are used to when looking at the OpenStreetMap Website.

And On-the-fly-projection should be activated.
