How it works
- Cubic yards = area × depth (ft) ÷ 27. Tons = yards × weight per yard — typical values are filled in; ask your supplier.
- Extra covers settling (mulch, soil) and compaction (road base can lose 20%).
- Add your supplier's unit prices to any line for a cost estimate; tax and markup are optional.
How to measure
- Measure each bed or area; for curves use a circle or split into rectangles. Typical depths: mulch 2–3 in., gravel paths 3–4 in., driveways 4–6 in.
Estimates only. Coverage, sizes and waste vary by product and job — verify with the manufacturer's specs and your local building code before ordering.
