How long is it for each zoom level?



  • I have a question, how long is it for each zoom level?

    It looks like each zoom level doubles the distance it has.

    I measure it as follows, is it correct?
    Zoom nm
    10 ~= 83.2
    11 ~= 41.6
    12 ~= 20.8
    13 ~= 10.4
    14 ~= 5.2
    15 ~= 2.6

    Thanks

    Good question :) yes, you are correct each zoom doubles when you zoom in. In zoom 0 one pixel is roughly 156.5 km.
