Sand Calculator for Paver Joints
Estimate joint sand to fill the gaps between pavers.
Joint (polymeric) sand fills the narrow gaps between pavers to lock them together. Coverage depends on joint width and paver size, so this is an approximation based on a thin ~1-inch effective layer over the paved area — most projects use far less than the bedding layer.

Tip: Sweep polymeric sand into dry joints, then mist lightly to set it — too much water washes it out.
How it's calculated
1 cubic yard covers about 324 sq ft at 1 in deep; about 1.4 US tons per cubic yard; a 1 in bedding layer needs about 0.43 US tons per 100 sq ft.

Sand Calculator for Paver Joints FAQ
How much joint sand do I need for pavers?
Far less than bedding sand — joint sand only fills the gaps. A bag of polymeric sand typically covers 50–100 sq ft depending on joint width.
What is the difference between bedding and joint sand?
Bedding sand is the 1-inch setting layer under pavers; joint sand (often polymeric) is swept into the gaps between them to lock them in place.
