A plain gravel garden path: how deep, how much edging, how many bags
Quick answer
UC Master Gardeners call 2 inches of gravel a practical minimum for a path, or 4 inches if stepping stones or pavers will be set into it. Sakrete suggests a 2 to 4 inch base for walks. A 3 x 30 ft path at 3 inches takes 22.5 cubic feet: 0.83 cubic yards, 45 bags of 0.5 cu ft or 38 bags of 60 lb. Edging both long sides takes 60 feet.

How deep
Two inches, or four with stepping stones
A plain gravel path skips the sand and the pavers that a patio needs. It's one layer of stone, spread to an even depth and held in by an edge. A UC Master Gardener article on gravel paths calls 2 inches a practical minimum. If you plan to set thick stepping stones or pavers into the gravel, it says to allow 4 inches.

Sakrete's gravel data sheet agrees: it suggests a 2 to 4 inch drainage base for walks. So for a garden path, plan somewhere from 2 to 4 inches, deeper where you'll set stones or push a wheelbarrow.

Step by step
Measure, edge and fill the path
Lay out the path
Mark it with string and stakes, or a garden hose for curves. Measure the width in a few places and the length along the middle.
Pick the depth
Two inches for a path you only walk. Four if stepping stones go in, as the UC Master Gardener article says, or if a loaded wheelbarrow will use it.

Measure the edging
Edging runs along both sides, so it's twice the path length, plus the ends if you close them. Lay a hose along each edge of a curved path and measure the hose.
Choose stone that packs
Angular crushed stone packs into a nearly solid surface; round pea gravel never packs down fully and rolls underfoot. Smaller pieces are more comfortable to walk on.

Count the bags or tons
Run the calculator with the path size and depth, with the sand and paver fields left blank. It gives cubic feet, cubic yards and bags.
Spread, rake and tamp
Fill between the edges, rake level and tamp. Walk it for a week, then top up the low spots.

If the stone yard sells by the ton, the UC Master Gardener article gives a rough rule: one ton covers 80 to 120 square feet at 2 inches deep. For the 90 sq ft example path at 2 inches, that's about 0.75 to 1.13 tons. The range is wide because stones weigh differently, so ask the yard what a ton of its stone covers.

Edges and fabric
What holds the gravel in place
Without an edge, gravel walks off into the lawn and the beds. The UC Master Gardener article lists bender board, its plastic copies, rock, pavers, bricks and lumber as borders that keep it in. Any of them works as long as the edge runs the full length on both sides.

Tips and tricks
- Edge first, gravel second. Set the edging before any stone arrives. It gives you a clean line to rake to and stops the first loads spilling onto the lawn.
- Measure curves with a hose. The outside edge of a curve is longer than the inside edge. Lay a hose along each one and measure the hose.
- Buy a few extra bags. Tamping and foot traffic settle the stone. Keep a couple of bags back for the low spots after the first week.
- Price bags against a load. Past about a cubic yard, ask a stone yard for a bulk price and compare it with the bag total, delivery included.
Common questions
Questions
How deep should a gravel path be?
UC Master Gardeners call 2 inches a practical minimum and say to allow 4 inches if thick stones or pavers are set in. Sakrete suggests a 2 to 4 inch base for walks.

How many bags of gravel for a 3 x 30 ft path?
At 3 inches deep it's 22.5 cubic feet: 45 bags of 0.5 cu ft or 38 bags of 60 lb, which Sakrete lists at about 0.6 cu ft each. At 2 inches it's 30 or 25 bags.

How much does a ton of gravel cover?
A rough rule from UC Master Gardeners: one ton covers 80 to 120 square feet at 2 inches deep. Stones weigh differently, so ask the yard for its own figure.

Do I need sand under a gravel path?
No. The sand bed is for pavers to sit on. A plain gravel path is one layer of stone between edges, so leave the sand and paver fields blank in the calculator.
