Gravel should be at least 2-4 inches thick beneath the entire surface of the pavers, and the gravel size should be such that you can fit two layers of paver in between the large sizes. Using a geotextile fabric is also recommended to prevent weeds from growing up through the gravel and between the gaps of the pavers.
