By default e2fsck assumes the average file size is 8kB and allocates a corresponding number of inodes there. If, for example, you are storing lots of larger files there (digital photos, MP3s, etc) that are in the MB range you can use "-t largefile" or "-t largefile4" to specify an average file size of 1MB or 4MB respectively. You can also use -i or -N (see man page) to override the default bytes-per-inode value. This will also speed up e2fsck noticably.
