Bags of Sand for a 6x25 Walkway
How many bags of sand for a 6x25 walkway: at 2 inches deep you need about 25.0 cubic feet, which is 50 bags of the common 0.5 cubic foot size. If your store sells sand in 50-pound bags instead, figure about 50 bags, since sand weighs roughly 100 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 | 12.5 | 25 | 25 |
| 2 in | 25.0 | 50 | 50 |
| 3 in | 37.5 | 75 | 75 |
| 4 in | 50.0 | 100 | 100 |
How to figure it
- Area: 6 × 25 = 150 sq ft.
- Volume: 150 × (2 ÷ 12) = 25.0 cu ft.
- Bags: 25.0 ÷ 0.5 = 50 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 25.0 cubic feet is 0.93 yards, about 1.2 tons. Under a yard, bags save a delivery fee and are easy to haul in a car or pickup. Compare the bag price × 50 against a bulk quote for 1.4 tons delivered.
About sand
For paver bedding, concrete sand (coarse, washed) is the usual pick. Mason sand is finer and used in mortar and play areas.
Before you spread 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 tamp or wet and 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 sand
Works well for:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Think twice for:
- Driveway bases, since sand shifts under load
- Steep areas exposed to runoff
- Thick layers under pavers, which settle unevenly
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of sand (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 12x24 area at 3 inches takes about 3.6 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons 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.
- 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.
