How to Determine How Many Pavers You Need

Pavers are a great material for creating hardscaping features such as patios, walkways, pool decks, driveways, and more. They’re extremely durable and come in a variety of colors, shapes, and textures. You can create virtually any shape or design with them.Before you can begin installing your paver project, you’ll need to determine how many pavers your project requires. Estimating the number of pavers you need will help you estimate the cost of your project as well as ensure you don’t run out of pavers mid-project or end up with a lot left over.

The first step is to stake out the perimeter of your project. Pound wooden stakes into the ground along the edges of the space where the pavers will go. Place a stake every 6 feet along straight lines and every foot for curved areas. Tie string around the stakes to connect them and outline the perimeter. If your project has awkward angles or is a non-standard shape, break it up into sections that are standard shapes and measure each section separately. Calculate the area of each section and add them together to get the total area. The following formulas may come in handy:

  • To calculate the area of a rectangle, multiply the width times the length.
  • To calculate the area of a circle, multiply 3.1415 times the radius squared.
  • To calculate the area of a triangle, multiply the base times the height and divide by 2.

Next, determine the area of a single paver by multiplying the width times the length. Divide your total project area by the area of a paver and this will tell you the number of pavers you need. Make sure you use the same unit of measurement for both. If you measured your project area in square feet and your paver in square inches, you can convert your project area from square feet to square inches by multiplying the number of square feet by 144.

You should add at least 5 percent to your total, although 10 percent is recommended. This will ensure you have enough pavers after allowing for pavers that need to be cut to accommodate your design and any that get broken or cut incorrectly. In most cases, the pattern you create shouldn’t affect how many pavers you need. One exception is creating a diagonal pattern, which will require more. In this case, be sure to add at least 10 percent to your calculated amount.
