Paver Sand Calculator

Calculating the required paver sand relies on determining the total volume of the space you need to fill and factoring in the density of the sand material. First, find the surface area by multiplying the length by the width (Area = Length × Width). Next, multiply that surface area by your planned depth to get the total volume needed (Volume = Area × Depth). Finally, to find the weight, multiply the volume by the material density (Weight = Volume × Density). If you are buying by the bag or bulk yard, you can also multiply the total volume or weight by your local unit price to predict your total project cost.

Imagine you are building a backyard paver patio that measures 20 feet long by 15 feet wide, and you need to lay a leveling bedding layer of sand that is 1 inch (0.083 feet) deep. First, calculate the total area: 20 ft × 15 ft = 300 square feet. Second, calculate the volume: 300 sq ft × 0.083 ft = 24.9 cubic feet. To convert this into cubic yards for ordering bulk material, divide by 27, which gives approximately 0.92 cubic yards. Using a standard sand density of about 100 pounds per cubic foot, you will need roughly 2,490 pounds of sand. If sand costs $40 per cubic yard, your total material cost will be approximately $36.80.

Always order about 5 to 10 percent extra sand to account for spillages, uneven sub-grades, and joint settling. When filling paver joints, make sure the sand is completely dry before sweeping it in, as wet sand will clump on top of the pavers instead of falling deep into the joints. Finally, compact your bedding layer thoroughly before laying pavers to prevent future sinking and shifting.
