Figure one cubic yard of stone dust per 25 feet of 4-ft wide walkway at a 3-inch depth. The math: 100 sq ft × 3 ÷ 324 = 0.93 — round up. A 50-foot path takes about 2 yards; 75 feet, about 3.
Two ways paths get built
- Stone dust over compacted ground — the simple 3-inch walking surface
- Base + stone dust top — 3–4 inches of base gravel below, dust above; double the total
- Under pavers — stone dust also works as a 1-inch setting bed
Stone dust packs into a firm, sandy-smooth surface that sheds rain well — crown it slightly so water runs off the middle instead of pooling. Order #10 Stone Dust by the yard and size odd curves with the material calculator.
