How to Estimate How Many Pavers You Need for a Project
Adding pavers to your patio gives it a finished, textural appeal. You may also want to add a paved walkway from your patio or outdoor shed to the vegetable garden, or perhaps you just want to pave a small corner of your flower garden for a table and chairs. No matter the size of your project, you'll need to know how many pavers it takes to cover the area. Follow these few steps to estimate how many pavers you'll need for your project.
Measure the width and length of the area you intend to pave. Write the two figures down in a notebook.
Multiply the width by the length. The result is the square footage of the area. For example, a rectangular space measuring 25 by 15 feet equals 375 square feet.
Make a note that 1 square foot equals 144 square inches, because a square foot measures 12 inches by 12 inches, and 12 times 12 equals 144.
Visit the local garden center or local outlet for outdoor pavers. Bring your notebook and calculator.
If you like a paver that measures 12 inches by 12 inches, then you'll need 375 pavers to cover your 25 by 15 foot area. Purchase at least 10 percent more to allow for breakage and cuts.
But it's never that simple, is it? You like the paver that measures 8 inches by 4 inches. How many pavers do you need then to cover your 375 square feet?
One paver covers 32 square inches because 8 times 4 equals 32. One square foot equals 144 square inches. Divide 144 by 32. The result is 4.5. It takes 4 1/2 pavers to cover 1 square foot.
You then need to multiply the number of pavers needed per square foot by the square footage of the area. Staying with the example, you would multiply 375 by 4.5. The result is 1,687.5. You'll need that many pavers for the project, plus 10 percent more for breakage and cuts.
An alternative method is to convert the square footage of the area into inches and then divide that number by the number of square inches one paver covers.
For example: 375 square feet equals 54,000 square inches because 375 times 144 equals 54,000. One paver covers 32 square inches. 54,000 divided by 32 equals 1,687.5.
In the first formula, you convert inches to square feet to get the estimate. In the second formula, you convert square feet to inches. You have to use the same unit of measure in your equation to get a proper estimate.
Keep in mind the formula gives you an estimate only. Always purchase at least 10 percent more than the estimated amount to allow for mistakes and cuts.
