The runway lenght used for the taking off varied and depened on the weight of the plane and the runway type ( concrete or the grass ) For instance the G-8 with the heaviest bombs racked needed about 1200m of the runway for taking off. So the lighter Wurger was the shorther distance for taking off. I couldn't find the data for the ealier varinats eg. A-3/A-4 but it may be said it was about 350 m. Generally it can be estiamted that the runway lenght for the taking off could vary from 300 m to 500 m.
Fw 190 A-5 ... 391 m

Fw 190 F-8 ... 453 m
Fw 190 D-9 ... 317-450 m
Fw 190 D-12 ... 317 m
Fw 190 D-13 ... 317 m
