You can waste up to 64k per file. Tile-based mapping appears to use many files, it probably stores each tile in a file.

Actual filesystem usage:
$ gdu -sch MyDocs/.maps/Open*
14M MyDocs/.maps/OpenCycleMap
62M MyDocs/.maps/OpenStreetMap I
8.4M MyDocs/.maps/OpenStreetMap II
84M total

Actual bytes stored:
$ gdu -scbh MyDocs/.maps/Open*
8.8M MyDocs/.maps/OpenCycleMap
19M MyDocs/.maps/OpenStreetMap I
3.7M MyDocs/.maps/OpenStreetMap II
32M total
