How Much Gravel for a 4x10 Walkway?

A 4 by 10 foot walkway is 40 square feet. How much gravel for a 4x10 walkway depends on depth: at 3 inches it is about 0.37 cubic yards or 0.5 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 4x10 walkway

Area: 4 × 10 = 40 sq ft.
Depth in feet: 3 ÷ 12 = 0.250 ft.
Cubic feet: 40 × 0.250 = 10.0 cu ft.
Cubic yards: ÷ 27 = 0.37 yd³.
Tons: × 1.4 = 0.5 tons.

The volume and tonnage calculator does this for any size.

Gravel needed by depth

3 in	0.37	0.5	0.6
4 in	0.49	0.7	0.8

About gravel

Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. 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. This walkway sees foot traffic, so match the depth to that load rather than to the minimum.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 0.6 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 about 0.5 tons this job is small enough that bagged material could work; a 0.5 cubic foot bag holds about 1/54 of a yard, so compare the bag count with a bulk minimum.
Where it drops. Have the truck dump as close to the walkway as firm ground allows.

Good and poor uses for 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 12x24 area at 3 inches takes about 3.7 tons.
Weight used here: about 1.4 tons per cubic yard.

Where estimates go wrong

Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
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.
Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
