How much pea gravel for a 3×30 ft garden path?
A 3 × 30 ft garden path 3 inches deep takes about 1.26 tons of pea gravel, including a little for settling and 5% waste. Ask the yard for 1.5 tons (they sell by the half ton), or buy about 49 bags of 0.5 cu ft.
How to work it out
- 30 ft × 3 ft = 90 sq ft
- 90 sq ft × 3 in ÷ 12 = 22.5 cu ft ÷ 27 = 0.83 cu yd
- 0.83 cu yd compacted × 1.03 = 0.86 cu yd loose × 1.4 tons/cu yd = 1.2 tons
- + 5% waste = 1.26 tons
- Effective rate: ≈ 1.51 tons per cu yd compacted
- Bulk: 1.26 tons rounded up to the next ½ ton = 1.5 tons
- Bags: 24.3 cu ft loose ÷ 0.5 cu ft = 49 bags
Three feet is the width where two people can pass or a wheelbarrow runs without clipping the beds, and 30 ft is a typical run from a back door to a shed, a gate or the vegetable garden. At 90 sq ft and 3 in deep, it lands exactly where bags and a bulk half-ton step compete, so the choice comes down to how you want to move about a ton and a quarter of stone.

What to know about a 3×30 ft pea gravel path
Bags or bulk? Forty-nine bags of 0.5 cu ft is about 2,500 lb, which is several car trips and a lot of lifting, but it goes straight from the trunk to the path with no pile on the driveway. A landscape yard sells pea gravel by the half ton, so you would ask for a ton and a half and have a little left for top-ups. Many yards will load that into a pickup — check the payload on the door-jamb label first, because 1.5 tons is more than many half-ton pickups are rated for — or deliver it for a fee.
Dig the path out 3–4 in, rake the bottom flat and tamp it, then lay landscape fabric: one 3 ft wide strip runs the full 30 ft with no seam, and a handful of fabric staples holds it while you fill. Fabric stops the gravel sinking into the soil; it won’t stop every weed, because seeds land on top.
Edging is what makes a pea gravel path last. Both sides need it — 60 ft, plus 6 ft if you close the ends — set about an inch above the finished gravel so the stones don’t roll into the lawn. Steel or aluminum edging suits a curved path; treated timber or bricks on edge suit a straight one.
Pea gravel feels soft underfoot at more than about 3 in. For a firmer path, some people lay 2 in of compacted crusher run first and only 1–2 in of pea gravel on top. For a square seating area in the same stone, see how much pea gravel for a 10×10 patio; for a patch of angular stone, how much gravel for a 10×10 area.

What you’ll need
- Landscape fabric (woven or heavy non-woven)Budget price
Separates stone from soil under gravel and rock. Less useful under wood mulch, which breaks down into soil on top of it anyway.
See options on Amazon (opens in a new tab) - Steel or aluminum landscape edgingMid-range price
Rigid edging that holds gravel and pea gravel in place and keeps a clean line against lawn.
See options on Amazon (opens in a new tab) - Landscape fabric staplesBudget price
Pins fabric and edging down. Budget roughly one every few feet along seams and edges.

Frequently asked questions
Can I use crushed stone instead of pea gravel for a garden path?
Yes. Fine crushed stone packs firmer than round pea gravel, so it walks and wheels better, but it is less comfortable barefoot and can track dust indoors. Crushed stone with fines packs down more, so a 3 × 30 ft path at 3 in takes a little more tonnage; pick the stone in the calculator above to compare.
How much pea gravel for a 3×30 ft path 2 inches deep?
About 0.84 tons with settling and 5% waste: 1 ton from a yard, or 33 bags of 0.5 cu ft. Two inches works over a compacted crushed-stone base.
How much pea gravel for a 4 ft wide, 30 ft path?
About 1.68 tons at 3 inches deep, so ask for 2 tons — or about 65 bags. Four feet is wide enough for two people side by side.
