## How to Estimate How Much Gravel is Needed

Gravel and other landscaping material is often sold by the ton or the cubic yard. To find the weight of material in tons, the density of the material needs to be known, fortunately there are some common densities that can be used for these calculations. See common weights and densities of landscape material.

### Steps to Calculate Gravel and Landscaping Material

The first step to estimating gravel, sand, or soil is to estimate the volume of material needed. Start by measuring the length, width, and depth of the area you need to fill in the same unit of measurement.

Multiply the length, width, and height together to find the volume of the space. Now, convert the volume to cubic yards.

If the initial measurements were in inches, then convert cubic inches to cubic yards by dividing by 46,656. If the initial measurements were in feet then divide by 27 to get cubic yards.

As a shortcut, try our cubic yardage calculator to conveniently calculate your volume.

Armed with the volume of material needed in cubic yards, the weight of material in tons can be found by multiplying the volume by the material density. **Most gravel weighs 1.4 to 1.7 tons per cubic yard**. See below for more common material densities.

**For example**, let’s find the amount of gravel needed for a space that is 10 feet long, 10 feet wide, and 1 foot deep.

volume = length × width × depth

volume = 10′ × 10′ × 1′ = 100 cu ft

cu yds = 100 cu ft / 27 = 3.7

weight = cu yds × density

weight min = 3.7 × 1.4 = 5.2 tons

weight max = 3.7 × 1.7 = 6.3 tons

## Weight of Gravel and Other Landscaping Materials

Refer to the chart below for the weights of common landscaping material, including gravel, rock, sand, and soil.

Material | Weight per Cubic Yard | Weight per Cubic Meter | ||
---|---|---|---|---|

Pounds | Tons | Kilograms | Metric Tons | |

Gravel (¼” – 2″) | 2,800 – 3,400 lbs | 1.4 – 1.7 tons | 1,660 – 2,020 kg | 1.66 – 2.02 tonnes |

Rock (2″ – 6″) | 3,000 – 3,400 lbs | 1.5 – 1.7 tons | 1,780 – 2,020 kg | 1.78 – 2.02 tonnes |

Sand (wet) | 3,000 – 3,400 lbs | 1.5 – 1.7 tons | 1,780 – 2,020 kg | 1.78 – 2.02 tonnes |

Sand (dry) | 2,600 – 3,000 lbs | 1.3 – 1.5 tons | 1,540 – 1,780 kg | 1.54 – 1.78 tonnes |

Topsoil (wet) | 3,000 – 3,400 lbs | 1.5 – 1.7 tons | 1,780 – 2,020 kg | 1.78 – 2.02 tonnes |

Topsoil (dry) | 2,000 – 2,600 lbs | 1 – 1.3 tons | 1,190 – 1,540 kg | 1.19 – 1.54 tonnes |

Riprap | 3,400 – 4,000 lbs | 1.7 – 2 tons | 2,020 – 2,370 kg | 2.02 – 2.37 tonnes |
