Simply use the ll command and the size of directories will be your block size (cluster size in Windows speak):
$ ll /
total 40972
drwxr-xr-x 25 root root 4096 Apr 8 16:30 ./
drwxr-xr-x 25 root root 4096 Apr 8 16:30 ../
drwxr-xr-x 2 root root 4096 Mar 31 16:44 bin/
drwxr-xr-x 4 root root 4096 Apr 8 16:32 boot/
drwxrwxr-x 2 root root 4096 Aug 2 2018 cdrom/
My block size is 4,096 (4K) which is normal for an ext4 Linux file system. In your case it will be 64K and even a file of 1 byte will take 64K bytes on disk.
