How to Calculate Bags of Sand for a Patio Base

Homeowners have a lot of options for making an outdoor space into a livable and comfortable setting. One popular choice is a patio. Beautiful patios can be made from many different materials. Setting a good base for your patio is important, though, and the first step is to figure out how much sand you are going to need.

Step 1

Measure the length and width of your patio in feet.

Step 2

Multiply the length by the width to find the area of your patio in square feet.

Step 3

Multiply the area by 0.184. This will tell you how many 50-pound bags of sand you need for a 1-inch base of sand.

Step 4

Multiply the number found in Step 3 by the thickness of sand you want in your base. This new number is how many 50-pound bags of sand you will need for your project. Some contractors recommend a base of sand between 4 and 6 inches thick.
