How to Estimate How Much Gravel You Need
Gravel and other landscaping material are often sold either by the ton or the cubic yard, but most suppliers sell large volumes by weight in tons.
To find the weight of material in tons, you’ll need to know the approximate density of the material. Fortunately, there are some common densities that you can use for these calculations. See common weights and densities of landscape material.
Step One: Calculate Volume in Yards
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.
Step Two: Calculate Gravel Weight in Tons
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|
|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|
