Desired distance / A2 measure

• W-E 13580 m / 0.594 m https://www.google.com/search?q=13580%2F0.594 -> 22861
  • 13580 m / 0.494 m (only 5/6 of a foldable map) https://www.google.com/search?q=13580%2F0.494 -> 27490
• S-N 11130 m / 0.420 m https://www.google.com/search?q=11130%2F0.420 -> 26500
  • 10010 m / 0.420 m https://www.google.com/search?q=10010%2F0.420 -> 23833

25000

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

The distances on A2 are:

• W-E 14850 m
• S-N 10500 m.

The area is 14850*10500 = 155925000 m2 ~ 156 km2.

Pixel

300 dpi

I 300dpi => 300 px = 1 in
II 25.4 mm = 1 in
I=II 300 px = 25.4 mm => 300/25.4 px = 1 mm => 11.811023622 px = 1 mm

A2:

• 594 mm * (300 px/in) / (25.4 mm/in) = 7016 px
• 420 mm * (300 px/in) / (25.4 mm/in) = 4961 px

600 dpi

• 594/25.4*600 = 14032
• 420/25.4*600 = 9922

1 deg

• http://www.wolframalpha.com/input/?i=distance+between+0N13E+and+0N14E -> 111.3 km
• http://www.wolframalpha.com/input/?i=distance+between+52.51N13E+and+52.51N14E -> 67.89 km

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
