To give you an idea of the impact of using the different style, the table
below gives rough estimates of the final database size after import of a
2018 planet and after using the `--drop` option. It also shows the time
-needed for the import on a machine with 32GB RAM, 4 CPUS and SSDs.
+needed for the import on a machine with 32GB RAM, 4 CPUS and SSDs. Note that
+the given sizes are just an estimate meant for comparison of style requirements.
+Your planet import is likely to be larger as the OSM data grows with time.
style | Import time | DB size | after drop
----------|--------------|------------|------------
-admin | 5h | 189 GB | 20 GB
-street | 42h | 396 GB | 174 GB
-address | 59h | 497 GB | 251 GB

You can also customize the styles further. For an description of the
style format see [the developement section](../develop/Import.md).
**Important:** first try the import with a small extract, for example from
[Geofabrik](https://download.geofabrik.de).
