Zoom levels

Maps have an integer “zoom level” which defines the resolution of the current view.

• Level 0 (lowest zoom level): entire world can be seen on one map
• Level 21+: individual buildings

Each succeeding zoom level doubles the precision in both horizontal and vertical dimensions:

256 * 2^N dp

Approximation in miles:

16 = 1/4 mile, 15 = 1/2 mile, 14 = 1 mile, 13 = 2 miles, 12 = 4 miles, 11 = 8 miles

In meters per pixel:

zoom m/px
  19  0.19
  18  0.37
  17  0.74
  16  1.48
  15  3
  14  6
  13  12
  12  24
  11  48
  10  95
   9  190
   8  378
   7  752
   6  1,485
   5  2,909
   4  5,540
   3  10,064
   2  16,355
