Area

Desired area

Area encircled by the S-Bahn Ring, on a street map approximated by the A 100.


On online maps

Central point of desired area

Distances of desired area

A2 measures

ISO 216 A2 is 594 mm * 420 mm.

Desired scale

Other

1 km

1 deg

So maybe in OSM this would be a scale of https://www.google.com/search?q=25000*111.3%2F67.89 = 1:40985.4175873 to get a 1:25000 map



25000

On a scale of 1:25000, 1 km corresponds to 0.04 m = 40 mm.

A2 25000

On a scale of 1:25000 that means 14850 m * 10500 m. That is 155925000 m2 or ~ 156 km2.

Max EW distance: http://www.wolframalpha.com/input/?i=distance+between+52.51N13.26134E+and+52.51N13.48E 0.2187 degree

A3 - 50000, A4 100000, A5 200000 would cover the same area.
