If you are looking into upgrading your driveway, the pea gravel calculator helps you calculate the precise amount of material you need to complete your project. By measuring the area and depth of your excavation we can provide you with the right conversion into tons of gravel.

Remember that the key to our gravel driveway calculator is to measure in cubic yards in order to figure out the right volume of rocks needed to cover the area of your driveway at the desired depth. The recommended depth is between 2 and 4 inches.

How to Measure Your Driveway

Before using our gravel calculator, you need to gather the following measurements from your work area:

  • Length in feet
  • Width in feet
  • Depth in feet

With each of these measurements in hand, use this formula:

Length in feet X Width in feet x Depth in feet / 27

The result will be the number of cubic yards of material needed for your project.

The most essential step of the process is the correct measurement of your driveway or desired project area. Make sure to account for any other adjacent areas that need coverage as well.

Breaking Down Shapes

Sometimes you will face irregular or odd-shaped areas that need a bit of creativity to measure them correctly. Try breaking them down into the nearest possible shape. If you have an oval, you can break it down into a circle cut in half by a rectangle. Estimate triangles by drawing the completing rectangle and then dividing the area in half.

Types of Gravel

Merchants divide gravel by size, shape and color. Some of the most popular types are:

  • base #3
  • pea gravel
  • quarry process
  • white marble chips
  • crushed stone
  • stone dust
  • river rocks
  • item #4

The colors range from deep gray to tan and yellow tones. You can also find white and light gray colors in washed stone and base gravel #3. Also consider the size of rock you prefer to use.

Things To Consider

Even when using a driveway gravel calculator, is important to look for the advice a professional. In big projects, a miscalculation could mean ordering too much and wasting time and money in the process. Make sure you prepare for accidental loss or project modification by ordering 5 to 10% extra. For your reference, a cubic yard of washed gravel weight around 2,835 pounds.
