Frequently Asked Questions (FAQs)

1. How to calculate gravel for driveway?

Formula: (Length × Width × Depth) ÷ 27 = Cubic yards. Example: 20ft × 12ft × 4in (0.33ft) = 79.2 ft³ ÷ 27 = 2.93 yd³. Weight: 2.93 × 1.4 tons/yd³ = 4.1 tons. Standard driveway 4 inches deep. Heavy traffic 6 inches. Calculator handles all automatically!

2. How much does a cubic yard of gravel weigh?

Weight varies by type: Crushed Stone 1.4 tons/yd³ (2,800 lbs), Pea Gravel 1.3 tons/yd³, River Rock 1.2 tons/yd³, Limestone 1.3 tons/yd³, Decomposed Granite 1.35 tons/yd³, Lava Rock 0.7 tons/yd³. Calculator shows weight for each type automatically.

3. What depth of gravel do I need?

Depth by use: 2 inches - light decorative/paths. 3 inches - garden walkways. 4 inches - DRIVEWAYS (most common). 6 inches - heavy traffic/RVs. 8 inches - commercial parking. Calculator supports all depths with automatic quantity adjustment.

4. How much gravel for circular area?

Formula: π × (Diameter÷2)² × Depth ÷ 27. Example: 12ft diameter × 3in deep = 3.14 × 36 × 0.25 ÷ 27 = 1.05 yd³. Calculator has circular option - just enter diameter and depth, it calculates automatically!

5. What are different gravel types?

7 types available: Pea Gravel (walkways), Crushed Stone (driveways - best), River Rock (decorative), Limestone (base), Decomposed Granite (paths), Marble Chips (accent), Lava Rock (drainage). Each has different density affecting weight and cost. Calculator includes all!
