How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches.
  4. Read cubic yards, tons and cubic feet results.

Your Gravel Sand Calculator turns three simple measurements—length, width, depth—into the three quantities contractors quote: cubic yards, tons, and cubic feet. Knowing cubic yards tells you how many bulk bags to order; tons helps you compare pricing by weight; cubic feet is useful for small‑scale jobs or when a supplier quotes in feet. The tool first converts depth from inches to feet, multiplies by length and width to get volume in cubic feet, then divides by 27 for cubic yards. It multiplies cubic yards by 1.3 to give an approximate tonnage. For example, a 10 ft × 12 ft area at 4 in depth yields about 1.5 yd³, roughly 2 tons, or 40 ft³. Results appear instantly, so you can adjust dimensions and see the impact on material needs.

Pro tips

  • Add 5‑10% extra for compaction and spillage.
  • Round up to the nearest half‑yard for bulk orders.
  • Order sand by weight if the supplier lists tons; use the ton estimate to verify.
  • Double‑check depth conversion; 1 in = 0.0833 ft.

Real-life examples

  • A homeowner preparing a 12 ft × 15 ft patio with a 3‑inch sand base.
  • A landscaper estimating sand for a 200‑ft driveway drainage layer.
  • A contractor sizing gravel sand for a 5‑inch trench under a new foundation.

Case study

Mike needed sand for a 10 ft × 20 ft patio at 4 in depth. Using the calculator he saw he required 2.2 yd³ (≈2.9 tons). He ordered 2.5 yd³, avoided a costly over‑order, and completed the job on budget.

Frequently asked questions

How do I convert the calculator’s cubic yard result to the number of sand bags I need?
One sand bag is typically 0.5 cubic yard; divide the cubic yard total by 0.5 and round up.
Why does the ton estimate differ from the supplier’s quoted weight?
The calculator uses 1.3 tons per cubic yard, a standard average; actual sand density can vary slightly.
Can I use the calculator for gravel instead of sand?
Yes, but adjust the weight factor; gravel is heavier than sand, so the ton estimate will be higher.
What if my project area isn’t a perfect rectangle?
Break the area into smaller rectangles, calculate each separately, then add the results.
Do I need to include a waste factor?
Add 5‑10 % to the final cubic yard number to cover compaction and spillage.
