# Paver Base Calculator

Calculate the amount of gravel and sand needed for the base for a paver patio, path, or driveway project. Enter the size of the project and desired depth of the base materials to get an estimate of gravel and sand required.

## How to Estimate Paver Base Sand and Gravel

A beautiful and long-lasting paver patio starts with a solid base. A paver base consists of a layer of crushed gravel topped with a layer of sand.

A solid base will prevent the pavers from shifting, sinking, and upheaving.

### How to Find Cubic Yards of Base Material

To estimate the cubic yards of sand and gravel needed for a paver base follow these steps:

- Measure the length and width of the patio in inches
- Multiply the length and width to find the area in square inches
- Multiply the area by the gravel depth in inches to find the volume in cubic inches
- Divide gravel cubic inches by 46,656 to find the amount of gravel in cubic yards
- Multiply the area by the sand depth in inches to find the volume in cubic inches
- Divide sand cubic inches by 46,656 to find the amount of sand in cubic yards

### How to Find Cubic Meters of Base Material

Finding the cubic meters of sand and gravel needed is very similar to the steps above, with slight changes:

- Measure the length and width of the patio in centimeters
- Multiply the length and width to find the area in square centimeters
- Multiply the area by the gravel depth in centimeters to find the volume in cubic cm
- Divide gravel cubic cm by 1,000,000 to find the volume of gravel in cubic meters
- Multiply the area by the sand depth in centimeters to find the sand volume in cubic cm
- Divide sand cubic cm by 1,000,000 to find how much sand is needed in cubic meters

## How Deep Should a Paver Base Be?

For a typical patio, a paver base should consist of a 4″ layer of gravel with a 1″ layer of sand. For heavier duty applications such as commercial spaces or driveways a 6″ to 8″ layer of gravel should be used.

## Amount of Paver Base Material Needed for a Patio

Patio Size | Gravel Needed (4″ base) | Sand Needed (1″ base) |
---|---|---|

50 sq. ft. | 0.62 cu. yds. | 0.15 cu. yds. |

100 sq. ft. | 1.23 cu. yds. | 0.31 cu. yds. |

150 sq. ft. | 1.85 cu. yds. | 0.46 cu. yds. |

200 sq. ft. | 2.47 cu. yds. | .62 cu. yds. |

250 sq. ft. | 3.09 cu. yds. | 0.77 cu. yds. |

300 sq. ft. | 3.7 cu. yds. | 0.93 cu. yds. |

350 sq. ft. | 4.32 cu. yds. | 1.08 cu. yds. |

400 sq. ft. | 4.94 cu. yds. | 1.23 cu. yds. |

450 sq. ft. | 5.56 cu. yds. | 1.39 cu. yds. |

500 sq. ft. | 6.17 cu. yds. | 1.54 cu. yds. |

550 sq. ft. | 6.79 cu. yds. | 1.7 cu. yds. |

600 sq. ft. | 7.41 cu. yds. | 1.85 cu. yds. |

650 sq. ft. | 8.02 cu. yds. | 2.01 cu. yds. |

700 sq. ft. | 8.64 cu. yds. | 2.16 cu. yds. |
