About this calculator

12x12 is a slightly larger patio footprint that comfortably fits a dining set and a grill. This calculator defaults to that size with standard 4x8-inch pavers and returns the paver count, gravel base, sand, and total cost needed for the project.

FormulaPavers = CEILING((Area × (1 + Waste%)) ÷ Paver Area). Gravel Tons = Area × Base Depth(ft) × 100 lb/cf ÷ 2000. Sand Tons = Area × (1/12) × 100 ÷ 2000.
