minimum joists sizing

I have read a bunch about the 2x10 16" center joists. I will crawl under house in next few days, but in the meantime, what will need to be done if they are not these measurments? I will installing porcilean flooring in entry way and kitchen. I also am sure that I have 3/4" part board as my flooring underneath my vinyl. Do I need to replace w/ plywood and then backerboard? Thanks for the help

There can be a lot of variables, see what's there first.

If you have particalboard for a subfloor the tile is a no-go from the git-go. If you have OSB (oriented strand board) then it's possible but you can't tile directly to the OSB either.

All of the information that comes from the Tile Council of America recommendations start with exterior grade plywood for an absolute minimum, but again, there are some allowable variations.

Just measure your joist size, spacing and unsupported span. All 3 factor into the equation. Post back and we'll let you know. There's also a good chance you have osb subflooring and not particle board, although there could be a thin underlayment of particle board under the vinyl. Post back with your subfloor makeup as well.
