Frequently Asked Questions (FAQ)
How do I calculate rock and gravel weight?
Multiply the length, width, and depth in feet to find the volume in cubic feet. Divide by 27 to convert to cubic yards. Multiply by the material density (typically 1.25 to 1.4 tons per cubic yard) to determine total tons needed.
How thick should landscape rock be?
For pathways and flower beds, a depth of 2 to 3 inches of rock is typical. For larger stones, depth should match the average stone size.
What is the density of standard gravel?
Standard crushed gravel weighs approximately 2,700 pounds per cubic yard, or roughly 1.35 tons.
How many square feet does a ton of rock cover?
A ton of rock covers approximately 80 to 100 square feet at a 2-inch depth.
