  • Climate And Weather Conditions

When deciding what size gravel for driveway, climate and weather conditions should be taken into consideration. Gravel that is too small can easily be washed away during rain or snow storms, while larger gravel sizes provide more stability and resistance to the elements.

  • Soil Composition And Stability

When choosing what size gravel for driveway, it is important to consider the soil composition and stability of the area. The soil type can influence the ease with which gravel can be laid and how well it will settle into place. Additionally, the stability of the soil should be taken into account when selecting a particular gravel size as an unstable foundation could lead to shifting or washing away over time.

  • Type Of Traffic The Driveway Will Receive

When choosing a gravel size for a driveway, it is important to consider the type of traffic that it will receive. For example, if there will be heavy-duty vehicles such as large trucks or tractors driving over the driveway regularly, then you should use larger-sized gravel. On the other hand, if the traffic mostly consists of smaller cars and other light vehicles, then you can use smaller gravel sizes that are more affordable.

  • Desired Appearance Of The Driveway

When choosing gravel size for a driveway, desired appearance is an important factor to consider. Different sizes of gravel can create a variety of appearances, from the more natural and rustic look of smaller-sized gravel to the more formal, sophisticated look of larger-sized gravel.

Coarse Gravel (1-2 inches)

Coarse gravel, which is 1-2 inches in size, is the best for driveways that will primarily be used for heavy vehicles such as trucks and SUVs. This type of gravel can handle the increased weight and pressure better than smaller sizes of gravel due to its increased durability and stability.

Medium Gravel (3/4 inch)

Medium gravel at 3 to 4 inches is best for driveways that will primarily be used for light vehicles such as cars and motorcycles. Coarse gravel at 1 to 2 inches can also be used, but it tends to create a rougher ride. For heavy vehicles such as trucks, larger gravel sizes should be used for a smoother experience.

Fine Gravel (1/4-1/2 inch)

Fine gravel which is 1/4-1/2 inch in size, is best for driveways that will primarily be used for foot traffic or as a decorative element. This size of gravel provides more comfort underfoot and also ensures drainage for any water that may accumulate on the driveway.
