Quick Tips Before You Order Materials
Should I order extra material to be safe?
Yes, it's recommended to order around 5–10% extra to account for settling, compaction, or minor miscalculations. Material like mulch compresses, and gravel may shift during leveling.
What depth should I use for mulch, gravel, or concrete?
For mulch, 2–3 inches is typical. For gravel driveways, 4–6 inches is recommended. For concrete slabs, 4 inches is standard for patios and sidewalks, while driveways often use 5–6 inches.
Can this calculator be used for soil or sand?
Yes! This cubic yard calculator works for any bulk material measured by volume, including topsoil, sand, compost, rock, or fill dirt.
Frequently Asked Questions
- How do I calculate cubic yards of concrete?
- Multiply length × width × depth (all in feet), then divide by 27 to convert cubic feet to cubic yards. For example, a 10×10 foot slab at 4 inches thick = 10 × 10 × 0.33 ÷ 27 = 1.23 cubic yards.
- How deep should mulch be?
- For most landscaping, 2-4 inches of mulch is ideal. Use 2-3 inches for flower beds and 3-4 inches for pathways and weed suppression. Avoid piling mulch against tree trunks or house foundations.
- How much gravel do I need for a driveway?
- A standard gravel driveway needs 4-6 inches of depth. For a 12×50 foot driveway at 4 inches deep, you'd need about 7.4 cubic yards of gravel, or roughly 10-11 tons depending on gravel type.
