All new ArcGIS Online map services now use the Google Maps/Bing Maps (formerly Microsoft Virtual Earth) tiling scheme. For information on migrating from the ArcGIS Online tiling scheme to the Google Maps/Bing Maps tiling scheme, see Migrating map tiling schemes.
For information on older maps using the ArcGIS Online tiling scheme, see Common attributes for maps using the ArcGIS Online tiling scheme.
ArcGIS Online maps and layers in the Google Maps/Bing Maps tiling scheme use the same coordinate system, map DPI, and tile size. Cached levels of detail for each map and layer match; however, not all maps and layers contain all levels of detail.

Coordinate system: Web Mercator Auxiliary Sphere (WKID 102100)
Units of measure: Decimal degrees
| Global Extent: |

Maximum Longitude: Approx. 180 |
|
|
Maximum Latitude: Approx. 85 | |

Minimum Latitude: Approx. -85 | |
Map DPI: 96
Tile Size of Map Cache: 256 pixels by 256 pixels
Levels of Detail: The number of cached levels of detail varies among map services. The scale levels are calculated, based upon the tile size (256 by 256) and the WGS 1984 Web Mercator coordinate system, such that when tiles are laid out starting at 180W and proceeding eastward, the final tile aligns perfectly (no overlap) with the first tile at the international date line.
These are the standard map scale and cell sizes:
