How much pea gravel for a 8x14 patio: at 3 inches deep you need about 1.04 cubic yards, which is roughly 1.5 tons at 1.4 tons per yard. The patio covers 112 square feet, so every inch of depth adds about 0.35 yards.

The math for a 8x14 patio

  1. Area: 8 × 14 = 112 sq ft.
  2. Depth in feet: 3 ÷ 12 = 0.250 ft.
  3. Cubic feet: 112 × 0.250 = 28.0 cu ft.
  4. Cubic yards: ÷ 27 = 1.04 yd³.
  5. Tons: × 1.4 = 1.5 tons.

About pea gravel

Because pea gravel is round, it never fully locks. Keep depths modest on walkways and patios so it does not feel like walking on a beach, and use edging. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.

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. Since the patio carries foot traffic and furniture, a little extra depth is cheap insurance.

Ordering tips

  • Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
  • Delivery size. 1.6 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 about 1.5 tons this job is small enough that bagged material could work; a 0.5 cubic foot bag holds about 1/54 of a yard, so compare the bag count with a bulk minimum.
  • Where it drops. Have the truck dump as close to the patio as firm ground allows.

Good and poor uses for pea gravel

Works well for:

  • Patios, walkways and dog runs
  • Play areas with proper depth and edging
  • Drainage around foundations when sized properly

Less suited to:

  • Driveways and steep paths, where it rolls and ruts
  • Under pavers as a base
  • Areas without edging

Quick reference numbers

  • Per inch over 100 sq ft: about 0.43 tons of pea gravel (0.31 cubic yards).
  • Per inch over 1,000 sq ft: about 4.3 tons.
  • Another size for comparison: a 8x16 area at 2 inches takes about 1.1 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.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
