Change joint width, joint depth, paver size, and bag coverage for your selected product.
Why joint width changes the answer
A coverage-per-bag estimate works well for quick planning, but real coverage changes with joint width and joint depth.
A wider joint consumes more sand even when the patio area stays the same. Use your product's coverage chart when it lists coverage by joint width.
Buying advice
Round up rather than trying to buy exact sand. Edges, cuts, textured pavers, and sweeping loss can all increase consumption.
Unopened bags may be returnable depending on the store, while running short can interrupt installation.
