How to Convert Oven Recipes to Air Fryer
Topsoil is sold by the cubic yard (bulk) or by the bag. Knowing your area and the depth of soil you need makes ordering easy.
The basic rule:
- Formula: Area (sq ft) × Depth (inches) / 12 = cubic feet. Divide by 27 for cubic yards
- Topsoil weighs approximately 2,200 lbs per cubic yard (1.1 tons). Wet soil can weigh up to 3,000 lbs/yd³
- A standard dump truck holds about 10 cubic yards. Half-ton pickups can carry about 1 cubic yard safely
Always order screened topsoil for gardens and lawns — it is free of rocks, roots, and debris. For filling large areas, unscreened fill-grade topsoil is cheaper. Mix in compost (25-30% by volume) for the best growing results.

Frequently Asked Questions
How much does a cubic yard of topsoil weigh?
Dry topsoil weighs about 2,200 lbs (1.1 tons) per cubic yard. Moist topsoil can weigh 2,500-3,000 lbs per yard. This matters for delivery and for knowing what your truck or trailer can handle — a half-ton pickup should carry no more than 1 cubic yard.
How much topsoil do I need for a new lawn?
For a new lawn, apply 4-6 inches of topsoil over the existing grade. A 1,000 sq ft lawn at 6 inches deep requires about 18.5 cubic yards (roughly 2 dump truck loads). Grade the soil so it slopes away from your house for drainage.
What is the difference between topsoil and garden soil?
Topsoil is the top layer of natural earth, screened to remove debris. Garden soil is topsoil blended with compost, peat, and other amendments for better plant growth. Use topsoil for filling and grading; use garden soil for planting beds and containers.
How many bags of topsoil are in a cubic yard?
A 40-lb bag of topsoil contains about 0.75 cubic feet. You need about 36 bags to equal one cubic yard. Bagged soil costs $3-$6 per bag ($108-$216 per yard) — far more expensive than bulk delivery at $20-$50 per yard.
When is the best time to add topsoil?
Spring and early fall are ideal for adding topsoil. The soil should be dry enough to work — not muddy or frozen. For new lawns, apply topsoil 4-6 weeks before seeding. Avoid spreading topsoil in heavy rain, as it will compact and may wash away.
How many truckloads do I need?
A standard dump truck holds 10-12 cubic yards. A tandem axle dump truck holds 14-16 yards. A pickup truck can carry about 1 cubic yard (1 ton). Use our calculator to get your cubic yard total, then divide by your truck capacity to estimate loads.
