Bags of Pea Gravel for a 5x10 Walkway
How many bags of pea gravel for a 5x10 walkway: at 3 inches deep you need about 12.5 cubic feet, which is 25 bags of the common 0.5 cubic foot size. If your store sells pea gravel in 50-pound bags instead, figure about 26 bags, since pea gravel weighs roughly 104 pounds per cubic foot.
Volume and tonnage calculator →Bag count by depth
| Depth | Cubic feet | 0.5 cu ft bags | 50 lb bags (approx.) |
|---|---|---|---|
| 1 in | 4.2 | 9 | 9 |
| 2 in | 8.3 | 17 | 18 |
| 3 in | 12.5 | 25 | 26 |
| 4 in | 16.7 | 34 | 35 |
How to figure it
- Area: 5 × 10 = 50 sq ft.
- Volume: 50 × (3 ÷ 12) = 12.5 cu ft.
- Bags: 12.5 ÷ 0.5 = 25 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 12.5 cubic feet is 0.46 yards, about 0.6 tons. Under a yard, bags save a delivery fee and are easy to haul in a car or pickup. Compare the bag price × 25 against a bulk quote for 0.7 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.
Install tips for a walkway
- 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.

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
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 15x30 area at 4 inches takes about 7.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
