I'm going to put in a small patio in my back yard, and am reading up on all the DIY info. My local store sells PaveStone brand pavers. I noticed some info on the pavestone.com website, and want to see if people think it is reasonable.

For small pavers (6 to 8 inches length and width), PaveStone recommends the usual ~6 inches of crushed rock, then 1 inch of sand under the pavers. This matches a lot of other things I've read.

For large concrete patio stones (16 inches wide), they say that the crushed rock is unnecessary. They say to use only 1 inch of sand on top of the soil, and then compact it before laying the stones. This method would save me a good bit of effort and money, so the large stones are looking very desirable.

Can one really get away with a lesser base for large patio pavers/stones vs. smaller pavers?

Any input is appreciated.
