How Much Will a Ton of Gravel Cover?
The short answer: about 100 square feet at 2 inches deep. But the real number depends on depth and stone type — here is the full coverage chart, the formula, and worked examples so you order the right amount.
Gravel is sold by weight, but you buy it to cover an area — so the question everyone asks the supplier is the same: how far will a ton actually go? A single ton of gravel covers roughly 100 square feet at 2 inches deep. Go deeper and that number drops fast. This guide shows exactly how coverage changes with depth and stone type, and how to turn your own square footage into tons.
Ton of Gravel Coverage by Depth
Depth is the single biggest factor. The same ton spread thin covers a big area; laid deep for a driveway base it covers much less. These figures assume standard gravel at about 1.4 tons per cubic yard.
| Depth | Coverage per ton | Typical use |
|---|---|---|
| 1 inch | ≈ 200 sq ft | Light top-up / refresh |
| 2 inches | ≈ 100 sq ft | Paths, decorative cover |
| 3 inches | ≈ 80 sq ft | Walkways, patios |
| 4 inches | ≈ 60 sq ft | Driveway top layer |
| 6 inches | ≈ 40 sq ft | Full driveway base |
A quick shortcut: coverage per ton at any depth is roughly 200 ÷ depth in inches. So 2 inches gives 100 sq ft, 4 inches gives 50–60 sq ft, and so on. Our gravel coverage calculator does this instantly for any depth and stone type.
The Coverage Formula
Coverage works backwards from weight to volume to area. Because gravel weighs about 1.4 tons per cubic yard, one ton is about 0.71 cubic yards, or 19.3 cubic feet. Spread that volume at your chosen depth and you get the area:
Coverage (sq ft) = Cubic feet per ton ÷ Depth in feet
Example: 19.3 ft³ ÷ 0.167 ft (2 in) ≈ 115 sq ft (about 100 after settling)
To go the other way — from your area to the tons you need — the math flips. Multiply your square footage by the depth in feet, divide by 27 for cubic yards, then multiply by 1.4 for tons. The cubic yards to tons calculator handles that conversion for any material.
Worked Examples
Example 1: Garden Path
Area: 40 ft × 3 ft = 120 sq ft at 2 inches deep
Coverage per ton at 2 in: ~100 sq ft
Gravel needed: 120 ÷ 100 = 1.2 tons (order 1.25–1.5 tons with waste)
Example 2: Small Driveway Top Layer
Area: 20 ft × 12 ft = 240 sq ft at 4 inches deep
Coverage per ton at 4 in: ~60 sq ft
Gravel needed: 240 ÷ 60 = 4 tons (order ~4.5 tons with compaction)
Does Gravel Type Matter?
A little. Coverage is driven by weight per cubic foot, so lighter, smaller stone stretches further per ton than heavy, chunky stone. Pea gravel (about 1.35 tons/yd³) covers slightly more than dense crushed stone (about 1.5 tons/yd³), while large decorative rock covers less because bigger gaps mean fewer stones fill the same weight. In practice the swing is 10–15% at a given depth — enough to matter on a big order.
Don't Forget Waste and Compaction
Coverage charts describe finished, settled gravel. In the real world you lose material to uneven ground, spillage, and compaction, so add 5–10% to your order for decorative layers and 10–15% for compacted bases.

Hitting your target coverage depends on keeping the layer at a consistent depth. A bow rake screeds gravel level as you spread it, and a contractor wheelbarrow moves a ton from the delivery pile to the project without wearing you out.

Screeds and levels gravel to an even depth so your coverage matches the chart.
