Gravel Calculator
Estimate gravel needed by area and depth, in yards and tons.
Order the right amount of gravel
Gravel is sold by weight or by the cubic yard, so you need to turn your project’s area and depth into both. Guessing usually means an extra trip or a leftover pile.
Enter the dimensions and depth and it gives the volume in cubic yards and an estimated weight in tons using a typical density. A 30 by 10 foot path at 3 inches needs about 0.93 cubic yards.
