Walkway Gravel Calculator
Estimate the gravel for a garden path or walkway. Enter the length, width and depth to get cubic yards, tons and cost — pre-set to a 2-inch layer, the usual depth for a path you walk on.
Sets a typical depth — tweak anything below.
For a 25 ft × 3 ft area at 2 in deep, order about 0.51 cubic yards (0.69 US tons) of crushed stone.
Estimates only. Densities vary by moisture, compaction and supplier — confirm quantities before ordering.
How much gravel do I need for a walkway?
Multiply the path's length by its width for the square footage, then by the depth in feet, and divide by 27 for cubic yards. A 25 ft × 3 ft path at 2 inches deep works out to about 0.46 cubic yards — roughly half a yard, or 0.6 tons. That's small enough that a single pickup load covers it, and it's right at the line where bagged stone stops being silly. Enter your own path above for the exact number.
How wide should a garden path be?
This is the measurement people guess wrong. A path that only one person uses can be 2 feet, but it feels cramped; 3 feet is the comfortable single-file width and the most common choice. If two people are going to walk side by side, or you push a wheelbarrow or stroller down it, you want 4 feet — at 3 feet, one person steps off into the dirt. A main path from the drive to the front door reads better at 4 feet. Width drives your whole order: going from 3 to 4 feet on a 25-foot path adds a third more gravel.
What gravel is best for a walkway?
Angular crushed stone or decomposed granite, not smooth pea gravel. This is the opposite of what most people expect. Pea gravel looks lovely and feels soft, but the round stones never lock together — you sink slightly with every step, it's miserable with a stroller or a wheelchair, and it kicks out of the path into the lawn. Angular stone packs down into a firm surface you can walk on normally. If you want pea gravel anyway (plenty of people do, for the look and the sound), it works — just commit to solid edging and a 2-inch layer, no deeper, because depth is what makes loose stone feel like walking on a beach.
Do you need edging and fabric under a path?
Both, and edging matters more here than almost anywhere else. A path is a narrow strip of stone surrounded by soil and lawn, so it has a lot of edge relative to its area — without a border, gravel migrates outward and grass creeps in until the path blurs into the yard within a season. Steel or aluminum edging is the most durable; pressure-treated timber or paver soldiers also work. Under the stone, woven landscape fabric stops the path from sinking into soft ground and keeps weeds down. Overlap the fabric strips by about 6 inches.
Path width guide
| Path | Width | Feels like |
|---|---|---|
| Tight utility path | 2 ft | Single file, a bit cramped |
| Standard garden path | 3 ft | Comfortable single file |
| Two people side by side | 4 ft | Roomy; fits a wheelbarrow |
| Main entry walkway | 4–5 ft | Generous, reads as a front path |
Width drives the order more than people expect — 3 ft to 4 ft is a third more gravel over the same length.
Worked examples
- 25 ft × 3 ft = 75 sq ft
- 75 × 2 in (0.17 ft) = 12.5 cu ft
- 12.5 ÷ 27 = 0.46 cubic yards
- × ~1.35 ton/yd³ ≈ 0.6 tons
- 50 ft × 4 ft = 200 sq ft
- 200 × 2 in (0.17 ft) = 33.3 cu ft
- 33.3 ÷ 27 = 1.23 cubic yards
- × ~1.35 ton/yd³ ≈ 1.7 tons
- 12.5 cu ft needed
- 12.5 ÷ 0.5 cu ft per bag = 25 bags
- 25 bags ≈ $100+
- vs ~half a yard bulk ≈ $25–40
Common mistakes to avoid
- Building it too narrow. 2 feet feels cramped and 3 feet won't fit two people. Decide the width before you order — it changes the gravel amount as much as the length does.
- Using pea gravel on a walking surface. Round stone shifts underfoot and is hard work with a stroller or wheelchair. Angular crushed stone or decomposed granite packs firm.
- Going deeper than 2 inches. More depth doesn't make a path better — it makes loose stone feel like sand. Keep the walking layer around 2 inches over a firm, fabric-lined base.
- Skipping the edging. A path is nearly all edge. Without a steel, timber or paver border, the gravel spreads into the lawn and the path disappears in a season.
- Laying stone straight on soft soil. Without fabric the path sinks into the dirt and weeds come through. Woven fabric, overlapped 6 inches, fixes both.
Frequently asked questions
How much gravel for a walkway?+
A 25 ft × 3 ft path at 2 inches needs about half a cubic yard — roughly 0.6 tons, or 25 half-cubic-foot bags. Enter your path's length and width above for the exact figure.
How wide should a gravel path be?+
3 feet for a comfortable single-file garden path, 4 feet if two people walk side by side or you push a wheelbarrow down it. 2 feet works but feels tight.
How deep should gravel be on a path?+
About 2 inches over landscape fabric. Deeper isn't better on a walking surface — loose stone gets harder to walk on the deeper it goes.
Is pea gravel or crushed stone better for a walkway?+
Crushed stone, for walking. Its angular pieces lock into a firm surface, while round pea gravel shifts underfoot and is difficult with strollers or wheelchairs. Pea gravel wins on looks and feel underfoot — if you use it, edge it well and keep it to 2 inches.
Should I use bags or bulk for a path?+
A typical 25 × 3 ft path needs 25 bags at 0.5 cu ft each, which costs two to three times a bulk half-yard and means hauling 25 bags. Under about 10 bags, bagged is easier; past that, order bulk.
