Taking this on for the first time. Looks fairly straight forward.

I ripped up some cheesy tile we did not like and to make it easier I took the subfloor 1/2 inch particle board with it. I failed to ck if there was a gap on the perimeter of the subfloor.

When I go to replace the 1/2 inch sub floor for my laminate should I have a 1/4 ish gap or should I go right to the wall? I know with the laminate this is required for expansion.

Thanks
