Walkway Gravel Calculator — How Much Gravel for a Path?
Pre-set for a 2-inch pea gravel surface (≈1.4 tons/yd³) on a 3-foot-wide path. Straight paths use the Rectangle tab; winding paths and edging strips use Border.

Order 5–10% extra for compaction and settling — loose gravel always settles to less volume after compaction.
How much gravel does a walkway need? A 3-foot-wide, 50-foot path at 2 inches takes 0.62 cubic yards of gravel — about 0.86 tons, or 34 half-cubic-foot bags. Add a separate 2–3 inch compacted base layer underneath and steel or timber edging alongside. Enter your path's length and width above for exact amounts.
Walkway gravel depth: surface plus base
Build gravel paths as two thin layers — 2–3 inches of surface gravel over 2–3 inches of compacted base — rather than one deep layer of decorative stone. Deep loose gravel is no firmer to walk on and walks itself all over the yard; the compacted base carries feet and keeps the surface thin, crisp and cheap. The build sequence:
- Excavate 4–6 inches along the route; level and crown gently.
- Lay landscape fabric, overlapped 12 inches at seams.
- Spread 2–3 inches of #411 or crusher run and compact — a hand tamper is enough at path scale.
- Install edging: steel, brick, pressure-treated timber or stone.
- Top with 2 inches of surface gravel, slightly below the edging lip.
In the calculator, run depth 2 with your surface material, then depth 2–3 with #411 for the base, and order both amounts (5–10% extra each) — a 3 × 50 path works out to about 0.9 tons of pea gravel plus 0.9–1.4 tons of base.
Best gravel for walking paths
Pea gravel and decomposed granite are the two surfaces people actually enjoy walking on — pick DG for firmness, pea gravel for softness and price.
- Pea gravel (≈1.4 t/yd³) — rounded, barefoot-friendly, drains instantly; needs edging to stay put.
- Decomposed granite (≈1.4 t/yd³) — compacts firm, cleaner under wheelbarrows and wheelchair-friendlier.
- #67 or #8 crushed stone (≈1.4 t/yd³) — angular and locked-in; the pick for slopes, though harsher barefoot.
On any slope above roughly 1:12, favor DG or angular stone — pea gravel slowly migrates downhill with traffic and rain.
What a gravel path costs
In typical published US ranges, a DIY gravel path runs $3–$8 per square foot in materials — a 3 × 50 path lands around $450–$1,200 depending on stone choice and edging. Bulk pea gravel at $25–$60/ton keeps the stone bill modest; decorative edging and fabric are the line items people forget. Professional installation commonly quotes $10–$25 per square foot.

Frequently asked questions
How deep should a gravel walkway be?
Plan 2–3 inches of surface gravel over 2–3 inches of compacted base for a stable walking surface. Edging keeps the gravel contained; without it, rounded stones migrate onto lawns.
What is the best gravel for walking paths?
Pea gravel and decomposed granite are the most comfortable underfoot; DG compacts firm while pea gravel stays loose but drains freely. Angular crushed stone locks better on slopes but is harsher barefoot.
How do I keep gravel from spreading off the path?
Install steel, brick or timber edging at least 1 inch above the gravel surface, compact the base, and use angular stone or DG that locks together. A 2-inch layer is far less prone to kick-out than a deep one.
