Bags of Pea Gravel for a 8x14 Patio

How many bags of pea gravel for a 8x14 patio: at 3 inches deep you need about 28.0 cubic feet, which is 56 bags of the common 0.5 cubic foot size. If your store sells pea gravel in 50-pound bags instead, figure about 59 bags, since pea gravel weighs roughly 104 pounds per cubic foot.

How to figure it

  1. Area: 8 × 14 = 112 sq ft.
  2. Volume: 112 × (3 ÷ 12) = 28.0 cu ft.
  3. Bags: 28.0 ÷ 0.5 = 56 bags (round up).

Bags or bulk?

A cubic yard is 27 cubic feet, so 28.0 cubic feet is 1.04 yards, about 1.5 tons. Past about a yard, bulk is usually less work and often less money. Compare the bag price × 56 against a bulk quote for 1.6 tons delivered.

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.

Laying it down 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

Think twice 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 14x28 area at 2 inches takes about 3.4 tons.
  • Weight used here: about 1.4 tons per cubic yard.

Common estimating mistakes

  • Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
  • 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.
  • Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
