Usually by default its 4096.. Not sure about BSD though, sure its the same.

I think it can be changed during kernel compilation. I would also like to know how exactly to do it. Any help?

When your making your filesystem, you can specify the block size, which is the inode size in respect:

mke2fs -b 1024 /dev/hda1

its the -b flag that specifies this.
man mke2fs for more details.

Valid block sizes are 1024, 2048 and 4096 respectively.

Also during the install of Slackware, it will ask what size you want to use. Usually you want to use 4096 if you have a larger hard drive, if your using a small hard drive and want to save more space, use a smaller number. I don't believe there is another way to change your inode size unless after the filesystem is already created.. but don't quote me on that one.
