Paver Calculations

To determine how many paver stones you need:

  • Multiply the length and width (in feet) of the area you’re paving
  • Multiply the length and width (in inches) of your bricks or paving stones
  • Divide the brick or paver’s surface area by 144 to convert to square feet
  • Divide the total paving area by the paver’s surface area
  • Add an additional 10% to account for loss and waste

Sand Base Calculations

To find the amount of sand base you need:

  • Start with your total surface area from the first calculation
  • Divide the sand depth (in inches) by 12 to convert to feet
  • Multiply the surface area by the depth
  • Divide by 27 to convert to cubic yards
  • Add an extra 10% for waste

Sound difficult? Just plug your measurements into the calculator and it will take care of the rest!

Base Considerations

The amount of base you will need depends on how you plan to use the area. For example, if it’s a patio that’s mostly going to see foot traffic, a 4-inch base will be enough. For an area that might need some driving – like tractors or carts – you should probably use a thicker base. And for driveways, or any area where a heavy car might park, you want close to 12 inches of base.

Paver Stone Sizes

Traditional paver stones come in three typical sizes. Small stones are usually 0.2 square feet per stone, mediums are 1 square foot per stone and large ones are 1.71 square feet per stone. Some types, like Flagstone, come in uneven shapes. That means you have to make sure your design is well planned and that you have enough paver stones in case there are any mistakes.
