You usually have to look at mkfs for a specific filesystem (mke2fs on
Linux, newfs on Solaris, etc) to find the low-level options.  All those
filesystems that support it (i.e, forget trying it with mkdosfs or
mkisofs, and it's probably not meaningful on reiserfs or xfs either) say
pretty much the same thing:

       -i bytes-per-inode
              Specify  the  bytes/inode ratio.  mke2fs creates an
              inode for every bytes-per-inode bytes of  space  on
              the  disk.   The  larger the bytes-per-inode ratio,
              the fewer inodes will be created.  This value  gen-
              erally  shouldn't  be smaller than the blocksize of
              the filesystem, since then too many inodes will  be
              made.  Be warned that is not possible to expand the
              number of inodes on a filesystem after it  is  cre-
              ated,  so  be careful decided the correct value for
              this parameter.
