1) What stone dust does in garden builds
Stone dust is a fine screening that levels and “locks” hardscape layers. It is commonly used for paver bedding, walkway repairs, edging support, and shed pads. When placed over a stable base and compacted, it helps reduce rocking and movement while keeping surfaces even.
2) Measure the footprint with the right shape
Quantity starts with area. Use rectangle for straight paths and pads, circle for round patios, and custom when you already know total area from a sketch or site map. Keep all dimensions in one unit system so results stay consistent.
3) Choose thickness for the job
Many garden applications use 1 to 2 inches as a bedding layer after compaction. Leveling fills, grade corrections, or thin base builds may require 2 to 4 inches. If you need thicker placement, compact in lifts for better density and fewer future depressions.
4) Density links volume to weight
Suppliers may sell by cubic yard or by ton. Density bridges those pricing styles. A practical working range is 90 to 110 lb/ft3 (about 1450 to 1760 kg/m3). Moisture and fines content change density, so adjust the density input if you have ticket data.
5) Waste and compaction are real-world multipliers
Waste covers trimming, spillage, and uneven subgrade; 5% to 10% is common for small jobs. Compaction accounts for settlement when you tamp or vibrate; 8% to 15% is often realistic for loose deliveries. Using both produces an order quantity closer to reality.
6) Conversions the calculator performs
The tool calculates raw volume from area and depth, then applies waste and compaction to create an adjusted volume. It converts between cubic feet, cubic yards, and cubic meters, and estimates weight using your density. This supports comparing quotes across unit conventions.
7) Cost planning with delivery and tax
Material cost is computed from either tons or cubic yards, then delivery and sales tax can be added for a complete total. Compare pricing modes when minimum loads apply. If your supplier rounds to half-yard or half-ton increments, round your order upward after estimating.
8) Recordkeeping that improves future takeoffs
Exporting CSV or PDF helps you document inputs, assumptions, and totals for bids and invoices. Save the density you used and the delivered amount. Comparing estimates to actual tickets lets you fine-tune waste and compaction factors for your soil and installation methods. Over time, your takeoffs become reliable.
