Bags of Pea Gravel for a 10x14 Patio

How many bags of pea gravel for a 10x14 patio: at 3 inches deep you need about 35.0 cubic feet, which is 70 bags of the common 0.5 cubic foot size. If your store sells pea gravel in 50-pound bags instead, figure about 73 bags, since pea gravel weighs roughly 104 pounds per cubic foot.

How to figure it

  1. Area: 10 × 14 = 140 sq ft.
  2. Volume: 140 × (3 ÷ 12) = 35.0 cu ft.
  3. Bags: 35.0 ÷ 0.5 = 70 bags (round up).

Bags or bulk?

A cubic yard is 27 cubic feet, so 35.0 cubic feet is 1.30 yards, about 1.8 tons. At this size, a bulk delivery usually beats a cart full of bags once you count trips. Compare the bag price × 70 against a bulk quote for 2.0 tons delivered.

About pea gravel

Pea gravel is small, rounded stone, usually around 3/8 inch. It is comfortable to walk on and drains well, but it shifts under car tires and needs a solid edge to stay put.

Before you spread for a patio

  • Dig and level. Remove sod and set the base slightly below the surrounding grade.
  • Edge it. Steel, plastic or stone edging keeps material in place.
  • Spread in layers. Rake to depth, then rake smooth; rounded stone will not compact.
  • Buy a few extra. Grab 5 to 10 percent more bags for settling and touch-ups.

The volume and tonnage calculator handles other sizes and depths.

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

Poor fit for:

  • 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 20x25 area at 3 inches takes about 6.5 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Common estimating mistakes

  • Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
  • Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
  • Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
  • Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
