Polymeric Sand Calculator

How to calculate

Coverage changes with joint width, joint depth and paver shape. The 50 sq ft per bag input is an arithmetic example, not a product recommendation.

Worked example

Length (ft): 16 · Width (ft): 12 · Product coverage (sq ft / bag): 50 · Extra material (%): 10.

These inputs produce 5 bags to order. Change the measurements above to match your project.

Before you order

Use the coverage chart for your exact paver and joint dimensions. Bedding sand volume cannot predict polymeric sand demand.

For an irregular footprint, split the project into rectangles. Calculate each section and combine unrounded quantities before rounding the final order. Ask the supplier to confirm product yield and available package sizes.
