OpenStreetMap – Tile Usage wiki.openstreetmap.org/wiki/Tile_Disk_Usage OSM does NOT pre-render every tile. Pre-rendering all tiles would use around 54,000 GB of storage. The majority of tiles are never viewed. In fact just 1.79% have ever been viewed. This is because the majority of tiles are at zoom level 18 and the vast majority of those contain nothing of interest (they're entirely blue) By following an on-the-fly rendering approach we can avoid rendering these tiles unnecessarily. The tile view count column shows how many tiles have been produced on the OSM Tile server. Tile server disk usage: 1,272 GB used. (6 Jan 2012). (z0 to z15: 252 GB, z16 to z18: 1,020 GB)
