SUMMARY
This article lists the default cluster sizes for drives using the FAT32 file system. The FAT32 file system uses smaller default cluster sizes than the FAT16 file system, resulting in a more efficient file allocation system and the conservation of drive space.

The following tables lists the default cluster sizes used by the FAT32 file system.

  Partition size           Cluster size -  512 MB to 8,191 MB          4 KB   8,192 MB to 16,383 MB       8 KB   16,384 MB to 32,767 MB     16 KB   Larger than 32,768 MB      32 KB
