Instant pre-calculated material estimates for common US residential project sizes before compaction buffer:

Typical US Project	Area	Depth	Volume	Weight	Store Bags
Medium Lawn Section (1,000 sq ft)	1,000 sq ft	1/4 inch	0.86 cu yd	1,550 lbs	24 bags (1 cu ft)

Cubic Yards = (Area Sq Ft × (0.25 ÷ 12)) ÷ 27

Topdressing lawns at a 1/4-inch depth requires precise calculation to avoid smothering existing turf blades.

The ideal topdressing mix for leveling bumpy lawns is 70% clean masonry sand and 30% organic compost.

At 1/4 inch depth, you need roughly 0.77 cubic yards (plus 10% waste = ~0.85 cu yd).
