How much sand is needed to lay paving stones?

To lay paving stones, you typically need about 1 inch of sand as a base layer, which equates to approximately 0.5 cubic feet of sand for every 10 square feet of area. For a more precise calculation, measure the total area in square feet and multiply by the desired depth of sand in feet. It's essential to compact the sand before laying the stones to ensure stability and prevent shifting.
