How Much Gravel for a 5x40 Walkway?
How much gravel for a 5x40 walkway: at 3 inches deep you need about 1.85 cubic yards, which is roughly 2.6 tons at 1.4 tons per yard. The walkway covers 200 square feet, so every inch of depth adds about 0.62 yards.
Volume and tonnage calculator →The math for a 5x40 walkway
- Area: 5 × 40 = 200 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 200 × 0.250 = 50.0 cu ft.
- Cubic yards: ÷ 27 = 1.85 yd³.
- Tons: × 1.4 = 2.6 tons.
The volume and tonnage calculator does this for any size.
Gravel needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 1.23 | 1.7 | 1.9 |
| 3 in | 1.85 | 2.6 | 2.9 |
| 4 in | 2.47 | 3.5 | 3.8 |
| 6 in | 3.70 | 5.2 | 5.7 |
About gravel
Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. Weight per yard is a planning number; the scale ticket at the yard is the real one.
Preparing the walkway
Dig the path a few inches below grade, compact the bottom, add fabric if needed and install edging on both sides so the material stays on the walk. For foot traffic, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 2.9 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the walkway as firm ground allows.
Good and poor uses for gravel
Good uses:
- Rural driveways and lanes where low upfront cost matters
- Drainage areas and around downspouts
- Temporary access while a site is under construction
Poor fit for:
- Steep slopes, where loose stone washes downhill
- Spots plowed often, since plows push gravel into the lawn
- Areas next to doors, because stone tracks inside
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 8x16 area at 4 inches takes about 2.2 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- 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.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
