New brick paver patio is a great addition to a home, and it’s surprisingly easy to install using a base of sand and gravel instead of setting each brick with mortar. This method also allows you to quickly and easily replace bricks that are damaged. You’ll want to make sure you know how much gravel you need for a brick paver patio before you start installation.
Measure the Patio - Use a measuring tape to find the length and width of the proposed patio, and multiply the two figures to find the square footage. For example, if the planned patio is 10-by-12 feet, it is 120-square feet.For circular brick paver patios, measure the radius (the distance from the center to the edge) and use the formula 3.14* r^2 to find the square feet. For example, if the patio is to be 12-feet across, the radius is 6 feet, so you have 3.14*6^2 = 113 square feet.
