How much does a cubic yard of gravel weigh?

A cubic yard of typical gravel weighs between 2,400 and 2,900 pounds, or about 1.2 to 1.45 US tons. The exact weight depends on the type of rock and its moisture content.

How many square feet does a ton of gravel cover?

The coverage area depends on the depth. At 2 inches deep, one ton of gravel will cover approximately 100-120 square feet. At 4 inches deep, it will cover about 50-60 square feet.

What is the difference between a ton and a tonne?

A US ton (short ton) is 2,000 pounds. A tonne (metric ton) is 1,000 kilograms, or about 2,204.6 pounds. This calculator uses US tons.

Do I need to add a base layer?

For driveways or paths with heavy traffic, it's recommended to add a base layer of larger, more stable stone (like #3 gravel) before applying the top layer of decorative gravel.

How do I calculate gravel for an irregular shape?

Break down irregular areas into smaller, regular shapes like rectangles and circles. Calculate each section separately, then add the totals together.

Should I order extra gravel?

Yes, always order 5-10% more gravel than calculated to account for compaction, spillage, and uneven surfaces. It's better to have a little extra than to run short mid-project.
