			16" for the most part...some are maybe 12" just depending on how they framed around the crawl space.  I think I'm gonna make a spacer for each joist to give me additional stability though.  The joists are spanning 18-20' and move quite a bit.  I think adding a single spacer about midway to tie each joist to one another will be a good idea.
