I've always had good luck by doubling the current size of things when 
they hit capacity (lacking any more knowledge about what's going on 
anyhow).  If you do shrinking, I do it when the thing falls to around 
25% utilization and then shrink it by half.

Just my heuristic but I find it tends to find something close to the 
appropriate size pretty fast.
