Bags of Sand for a 5x50 Walkway
How many bags of sand for a 5x50 walkway: at 2 inches deep you need about 41.7 cubic feet, which is 84 bags of the common 0.5 cubic foot size. If your store sells sand in 50-pound bags instead, figure about 84 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 | 20.8 | 42 | 42 |
| 2 in | 41.7 | 84 | 84 |
| 3 in | 62.5 | 125 | 125 |
| 4 in | 83.3 | 167 | 167 |
How to figure it
- Area: 5 × 50 = 250 sq ft.
- Volume: 250 × (2 ÷ 12) = 41.7 cu ft.
- Bags: 41.7 ÷ 0.5 = 84 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 41.7 cubic feet is 1.54 yards, about 2.1 tons. Past about a yard, bulk is usually less work and often less money. Compare the bag price × 84 against a bulk quote for 2.3 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.
When to choose sand
Works well for:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Poor fit 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 10x20 area at 4 inches takes about 3.3 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- 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.
- 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.
