How Much Gravel for a 12x10 Patio?

How much gravel for a 12x10 patio: at 3 inches deep you need about 1.11 cubic yards, which is roughly 1.6 tons at 1.4 tons per yard. The patio covers 120 square feet, so every inch of depth adds about 0.37 yards.

The math for a 12x10 patio

  1. Area: 12 × 10 = 120 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic feet: 120 × 0.250 = 30.0 cu ft.
  4. Cubic yards: ÷ 27 = 1.11 yd³.
  5. Tons: × 1.4 = 1.6 tons.

About gravel

Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

Preparing the patio

Remove sod, level the area with a slight slope away from the house, and lay landscape fabric if weeds are a concern. Edging keeps loose material inside the patio footprint. For foot traffic and furniture, the depths in the table above are a reasonable starting range.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 1.7 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
  • Bulk vs bags. At this size bulk delivery is usually the practical choice.
  • Where it drops. Have the truck dump as close to the patio as firm ground allows.

When to choose gravel

Best suited to:

  • Rural driveways and lanes where low upfront cost matters
  • Drainage areas and around downspouts
  • Temporary access while a site is under construction

Poor fit for:

  • Steep slopes, where loose stone washes downhill
  • Spots plowed often, since plows push gravel into the lawn
  • Areas next to doors, because stone tracks inside

Quick reference numbers

  • Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.3 tons.
  • Another size for comparison: a 8x16 area at 3 inches takes about 1.7 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Common estimating mistakes

  • Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
