I would gamble that your bytes-per-inode is 4096, as this is the default.
To verify, first find the number of inodes on your system (as root):

[prompt]# dumpe2fs /dev/hda1 |egrep '^Inode Count:'

Then, find the number of blocks:

[prompt]# dumpe2fs /dev/hda1 |egrep '^Block Count:'

Then, find the size of each block:

[prompt]# dumpe2fs /dev/hda1 |egrep '^Block Size:'

Then, do some math:

<Bytes per Inode> = <Block Count> * <Block Size> / <Inode Count>

and it should be close to 4096.  Allow some error for rounding, overhead,
or crap I didn't think of.

I'm sure there is an easier way, but DIIKI*
