How do I convert sq ft to cubic yards?
Multiply square footage by depth in feet to get cubic feet, then divide by 27. Example: 100 sq ft × 0.25 ft (3") = 25 cu ft ≈ 0.93 cu yd.

Use the mulch calculator for pre-set 3 inch mulch depth, or gravel calculator for path and driveway defaults.
Pickup truck and trailer loads
A full-size pickup holds roughly 1.5–2 cubic yards level with the bed sides. Weight varies: mulch ~400–800 lb/yd, gravel 2,000+ lb/yd — check payload before loading.
Waste and settling
Add 10% for spillage, uneven ground, and settling — especially on fresh topsoil or loose gravel. Adjust the waste slider in project settings before copying your shopping list.
