Pea Gravel Weight Calculator
Most bulk suppliers price pea gravel by weight — not by area. Before you call for a quote, convert your project dimensions to pounds, short tons, kilograms, and metric tonnes. This calculator uses a verified density of 100 lb/ft³ (1,602 kg/m³) from USGS aggregate data.
Pea Gravel Density: What the Numbers Mean
Pea gravel has a loose dry density of 100 lb per cubic foot — equivalent to 1,602 kg/m³ or 1.35 short tons per cubic yard. This figure comes from USGS Construction Sand and Gravel statistics and represents the mid-range density for rounded, water-worn gravel in the 3/8-inch size class.
Three factors shift that density in real projects:
- Stone size: Smaller 1/8-inch pea gravel packs tighter and runs slightly heavier per cubic foot than 3/8-inch. For most landscaping applications the difference is under 5%.
- Moisture content: Wet pea gravel weighs 5–10% more than dry. Quarries quote dry weight; the load on your truck after a rainstorm is heavier.
- Mineral composition: Limestone-based pea gravel (common in the US Midwest) runs 1.5–1.6 t/yd³. Granite-based and river rock-sourced gravel runs 1.35–1.45 t/yd³. Always confirm with your supplier before placing a large order.
Worked Example: 12×15 ft Patio at 3 Inches Deep
- Area: 12 × 15 = 180 sq ft
- Depth in feet: 3 ÷ 12 = 0.25 ft
- Volume: 180 × 0.25 = 45 cubic feet
- Weight in pounds: 45 × 100 = 4,500 lb
- Short tons: 4,500 ÷ 2,000 = 2.25 tons
- Metric tonnes: 4,500 ÷ 2,205 = 2.04 tonnes
- Add 10% waste: 2.25 × 1.10 = 2.48 tons to order
At a typical 2026 bulk price of $45 per ton, this patio costs approximately $112 in pea gravel material. Use the cost calculator to plug in your local supplier's price and get an exact figure.

| 1 cubic yard | 2,700 lb | 1.35 | 1,225 kg | 1.225 |
| ½ cubic yard | 1,350 lb | 0.68 | 612 kg | 0.612 |
| 5 cubic feet | 500 lb | 0.25 | 227 kg | 0.227 |
| 10 cubic feet | 1,000 lb | 0.50 | 454 kg | 0.454 |
| 1 cubic metre | 3,531 lb | 1.77 | 1,602 kg | 1.602 |
| 1 bag (50 lb) | 50 lb | 0.025 | 22.7 kg | 0.023 |
Pea Gravel Weight Per Square Foot by Depth
This table answers the structural question: how much load does a pea gravel layer add to a surface? Use it when checking deck, patio slab, or balcony load ratings.
| Depth | lb per sq ft | kg per m² | Equivalent to |
|---|---|---|---|
| 1 inch | 8.3 lb/sq ft | 40.5 kg/m² | About 4 bags per 100 sq ft |
| 2 inches | 16.7 lb/sq ft | 81.5 kg/m² | Standard path depth |
| 3 inches | 25.0 lb/sq ft | 122 kg/m² | Standard patio depth |
| 4 inches | 33.3 lb/sq ft | 163 kg/m² | Minimum driveway depth |
| 6 inches | 50.0 lb/sq ft | 244 kg/m² | Heavy-use driveway |
| 9 inches | 75.0 lb/sq ft | 366 kg/m² | Playground minimum (ASTM F1292) |
Pea Gravel Weight vs Vehicle Payload Ratings
Knowing the weight of your order tells you whether you can self-haul or need delivery. These are real-world payload limits — not the truck name.
| Vehicle | Safe Payload | Max Pea Gravel | Notes |
|---|---|---|---|
| Sedan / SUV trunk | 400–600 lb | ~4 bags (50 lb) | Bagged only — no bulk |
| Half-ton pickup (F-150, Silverado 1500) | 1,000–1,500 lb | 0.37–0.56 yd³ | Spread load evenly in bed |
| Three-quarter-ton pickup (F-250) | 2,000–2,500 lb | 0.74–0.93 yd³ | Can handle most single-yard orders |
| One-ton pickup (F-350) | 3,000–4,000 lb | 1.1–1.5 yd³ | Suitable for 1–1.5 yard loads |
| Single-axle dump truck | 10,000–14,000 lb | 4–5 yd³ | Standard landscape delivery |
| Tandem-axle dump truck | 20,000–26,000 lb | 8–10 yd³ | Large driveway / commercial orders |
Short Ton vs Metric Tonne — Which Does Your Supplier Use?
US landscape suppliers quote in short tons (2,000 lb). Imported product spec sheets and European suppliers use metric tonnes (2,205 lb). The difference is 10.25% — on a 5-ton order that's 500 lb. Always confirm which unit your supplier uses before comparing prices or placing an order.
| Unit | Equals | Common in |
|---|---|---|
| Short ton (US ton) | 2,000 lb / 907 kg | US landscape suppliers, quarries |
| Metric tonne (t) | 2,205 lb / 1,000 kg | EU, UK, spec sheets, some imports |
| Long ton (UK ton) | 2,240 lb / 1,016 kg | Rarely used — mostly historical |

Sources & Methodology
Density used: 100 lb/ft³ (1,602 kg/m³ / 1.35 short tons per cubic yard) for loose, dry pea gravel.
Formula: Weight (lb) = Volume (ft³) × 100. Short tons = lb ÷ 2,000. Metric tonnes = lb ÷ 2,205. Kilograms = lb × 0.4536.
