How Much Gravel for a 4x75 Walkway?
How much gravel for a 4x75 walkway: at 3 inches deep you need about 2.78 cubic yards, which is roughly 3.9 tons at 1.4 tons per yard. The walkway covers 300 square feet, so every inch of depth adds about 0.93 yards.
Volume and tonnage calculator →The math for a 4x75 walkway
- Area: 4 × 75 = 300 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 300 × 0.250 = 75.0 cu ft.
- Cubic yards: ÷ 27 = 2.78 yd³.
- Tons: × 1.4 = 3.9 tons.
The volume and tonnage calculator does this for any size.
Gravel needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 1.85 | 2.6 | 2.9 |
| 3 in | 2.78 | 3.9 | 4.3 |
| 4 in | 3.70 | 5.2 | 5.7 |
| 6 in | 5.56 | 7.8 | 8.6 |
About gravel
Because ’gravel’ covers so many products, the weight per yard moves with stone size and how much fine material is in the pile. Rounded stone with no fines rolls under tires; crushed stone with fines locks together. 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. Since the walkway carries foot traffic, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 4.3 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.
When to choose gravel
Works well for:
- 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
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
