Paver leveling beds use 1 inch of sand, sandboxes 2–3 inches (or more), and lawn leveling ¼–½ inch at a time. Sand weighs about 1.35 tons per cubic yard.

The math: 400 sq ft × depth in feet ÷ 27 = cubic yards. One cubic yard of sand covers 324 sq ft at 1" · 162 sq ft at 2" · 108 sq ft at 3".

Use coarse washed sand (paver/concrete sand) for bases and leveling — play sand is too fine and holds water.
