How the calculation works
Area uses length × width for a rectangle, π × (diameter ÷ 2)² for a circle, or your measured custom area. Bedding volume is area × compacted bedding depth.
Pavers and joints use a rectangular repeating grid: one cell is (paver length + joint width) × (paver width + joint width). Pavers are area ÷ cell area, rounded up. Joint fraction is 1 − paver face area ÷ cell area; joint volume is area × joint fraction × joint depth.
Weight, bags, and cost are calculated separately for bedding and joint sand. Raw volume × that product's density × (1 + allowance ÷ 100) gives order weight. Each bag count is its order weight ÷ its bag weight, rounded up; cost uses those rounded counts and their separate prices. The allowance is applied once.
The grid approximation is intended for rectangular pavers in straight, uniform joints. It does not model running-bond edges, irregular or mixed-size pavers, cut waste, slope, moisture, or a manufacturer's product-specific coverage. For polymeric sand, confirm the bag's coverage and permitted joint dimensions.
