Bag count by depth

Depth	Cubic feet	0.5 cu ft bags	50 lb bags (approx.)
1 in	28.0	56	59
2 in	56.0	112	117
3 in	84.0	168	175
4 in	112.0	224	233

How to figure it

Area: 14 × 24 = 336 sq ft.
Volume: 336 × (3 ÷ 12) = 84.0 cu ft.
Bags: 84.0 ÷ 0.5 = 168 bags (round up).

Bags or bulk?

A cubic yard is 27 cubic feet, so 84.0 cubic feet is 3.11 yards, about 4.4 tons. Past about a yard, bulk is usually less work and often less money. Compare the bag price × 168 against a bulk quote for 4.8 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.

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.

When to choose pea gravel

Good uses:

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 10x20 area at 4 inches takes about 3.5 tons.
Weight used here: about 1.4 tons per cubic yard.

Mistakes that throw off the order

Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
